WELCOME
Welcome to the AMERICAN SIGMA InSight Data Analysis Software manual.
This book introduces you to InSight Software and gets you started quickly. It
provides information on installing and using the InSight as well as details on
how to program a SIGMA Data Logger to collect data.
For more information about InSight, see the following topic, “How to find the
information you need.”
For a quick look at using InSight Software see The Basics chapter.
The Getting Started chapter that follows takes you through installation and
setup.
DOS & MICROSOFT® WINDOWS®
OPERATING SYSTEM VERSIONS OF
INSIGHT®
This manual describes the operation of both the DOS-based and Windows®based operating system versions of InSight.
The display screens are nearly identical for both versions. Where differences do
exist, the information will be identified with “InSight for DOS operating
system” or “InSight for the Windows® operating system” labeling.
The two versions of InSight application software are identified as follows:
NAME
InSight 
InSight 
For the Windows® Operating
System
OPERATING SYSTEM
DOS-based operating
system application
Windows® 95 / 98 / NT
operating system
PART NUMBER
4973
5254
InSight® will run under Microsoft Windows® as a DOS application with some
degradation in performance. You may prefer to run InSight directly from a DOS
prompt (without Windows® operating system running at all) for maximum speed
or if you experience any problems while running under the Windows® operating
system.
InSight® for the Windows® operating system will run under Windows® 95,
Windows® 98, or Windows® NT operating systems; it will NOT run under
Windows® 3.1 or Windows® 3.11 operating systems.

THE BASICS
FUNCTIONAL OVERVIEW
InSight Software lets you program your data logger, then quickly retrieve,
summarize and print your logged data.
To do this...
• Program your data logger using the Remote Programming feature of
InSight Software (Models 950/960/970 can also be programmed directly
from the front panel). Use InSight’s ‘Program Templates’ to speed
programming chores. Program Templates store all programming steps in a
disk file, letting you re-use common programs as often as you wish, quickly
and easily.
Next, after your data has been logged...
• Bring the logged data into InSight Software by retrieving it from a SIGMA
data logger (via modem or direct RS232 connection).
Finally,
• Select Site Files or Open Database from the toolbar or database window to
view or print a graph or tabular summary report of your data. Or open an
existing site file from disk to analyze or report on. Site files are
automatically named and stored to your hard disk when retrieved from the
logger.
That’s about all there is to it. For details on how to perform each of these tasks
see the following chapter, Using InSight.
PROGRAMMING
SIGMA loggers are easily programmed to meet your specific needs.
"Programming" means answering simple questions regarding primary devices,
units of measure or other features you have chosen.
When you are done programming you must "run" (or execute) the program
selections you have made. SIGMA models 904, 910, 920, 930 and 940 are
always in a running state except for certain conditions shown below which
cause a Program Complete state: 910, 920, 930 and 940 — no main power for
longer than 3 hours or full slate memory. 904 — full slate memory or loss of
main battery power for 70 minutes or battery discharge to less than 2.8 volts for
70 minutes or more.
For SIGMA 950/960/970 loggers you may run a program, stop a program or
resume a currently halted program.
When a program is running the following items are activated (if enabled during
programming):
• Data Logging
• 4-20 mA outputs
• Sampler control
• Alarm checking
AS041 Rev. 10-1-99
InSight Data Analysis Software
7
When a program is Halted (950/960/970 only) the following occurs:
• Logging continues with the last logged value
• 4-20 mA outputs remain unchanged
• Sampler control is disabled
• Alarm checking is disabled
When a program is Program Complete or Ready to Start the following occurs:
• No data logging
• 4-20 mA outputs stay at last value
• No sampler interface
• No alarm checking
The program status changes to Program Complete when:
• A program has been halted for longer than three hours
• Complete in that logger.
• See 904 meter’s manual for meaning of Program Complete in that logger.
Other InSight Features
Other InSight features include:
• Modem Scheduling - Automate data collection by scheduling multiple
loggers for unattended data retrieval at any time of day or night.
• Flow Simulator - Lets you perform a wide range of open channel flow
calculations. You may select any primary device (including Area/Velocity)
and enter a water level value (and velocity value, if needed). InSight will
calculate the flow for you.
• Program Templates - Store commonly used logger program setups on disk
for re-use whenever you wish.
• Password Security - For American Sigma loggers that now have the
password security feature built in, InSight checks for security settings and
prompts for password entry when the user connects to the logger in InSight.
After the correct password is entered the user can then: perform all the
standard InSight functions, enable or disable password security, change the
password, and even retrieve an encrypted readout of the password for
decryption by American Sigma Technical Support in those cases where a
password has been forgotten.

AS041 Rev. 10-1-99

DATABASE FILES
InSight Data Analysis Software
9
Each time you retrieve data from a logger, a site file is created in the
\INSIGHT\DATA\ directory of your PC.
Tip: To merge files into a
database during data
transfer you must have
the Database Toolbar
open.
Tip: Data editing is
performed in the Site
Data menu. Open a site
file to see the Site Data
menu.
A site file contains the following information:
• Logger Channel Data (level, flow, etc.).
• All Programmed Settings in the logger.
• Current Status of the logger at time of data retrieval.
• Sample History (if connected to a wastewater sampler).
• Event Log history of logger operation.
In addition to the site file, if the database toolbar is open on the main menu,
the new data is automatically merged with existing data from the same logger
into a database file.
Each time you retrieve logger data, with the InSight database toolbar open, the
following files are created:
• A standard site file is created in the \INSIGHT\DATA\ directory in your PC.
• A database file is created in the \INSIGHT\DATA\MERGE\ directory of
your PC.
• An editable copy of the database file is created in the
\INSIGHT\DATA\EDIT\ directory.
If the database toolbar is open when a data transfer is initiated, the following
Site Database menu is displayed after the data has been transferred. This menu
lets you decide whether to add the new data to a database file, or save it as an
individual site file:
Checking the ⌧ Merge File Into Database box confirms that you want to
merge this new data with the existing site database. New data will be appended
only to the end of the existing database file, even if the files overlap.
AS041 Rev. 10-1-99
InSight Data Analysis Software
10
Tip: If you elect not to
merge during data
transfer, the files can
always be merged at a
later time by using the
database toolbar on the
main menu.
If the ⌧ Save Data As Site File selection is checked then the data is stored as
an individual site file (in the \INSIGHT\DATA directory) and the files are not
merged into a database.
SITE FILE NAMING CONVENTIONS
Site files are named with the date and time of data retrieval (as reported by the
logger) and contain the permanent logger serial number in the file extension if
there is one (older model data loggers may not have an embedded serial number
and so the extension is set to “000”).
Example site file name: 03251734.3BF
Date
Time Embedded Serial Number of the Meter
03/25 17:34 3BF
Note that a 24-hr time format is used, where 17:34 is equal to 5:34 PM, for
example.
Tip: It is important that
you use unique
Site ID numbers in all of
your data loggers so that
InSight can
automatically manage
your data and files for
you.
DATABASE FILE NAMING CONVENTIONS
Database file names are labeled with the Site ID number of the logger.
Example database file name: 00000001.000
If data from two different loggers with the same Site ID are imported into a
database, InSight increments the file extension by one digit. For example, say
the 00000950.000 database already exists (from the unit with Site ID#
00000950) and you import data from a second logger having the same Site ID
but different program settings. InSight would automatically create a file called
00000950.001 to show that the data is from two different meters.
To make your database file names unique and easily recognizable, make sure
your loggers are all programmed with different Site ID numbers.
Only data from loggers with the same Site ID and with the same data logging
settings (exact same channels logged at the same recording interval) can be
merged. If you replace one logger with another at the same site, make sure the
new logger is programmed exactly the same as the old logger (same channels
logged at the same recording interval) if you expect to merge the new data with
the old data.
Merged and edited data files are always stored one level below the original site
file directory, wherever that may be. For example if your data directory is called
\DATA, then all merged database files would be stored in \DATA\MERGE and
the editable copy of the database file is stored in the \DATA\EDIT directory.

Export To ASCII — InSight for DOS operating system (Only)
Creates a comma-delimited ASCII (text-only) file on disk and is a feature
provided in the event someone has a need for a comma-delimited text file. Note
that All logged readings are exported when this feature is used; however, you
may enter a start and end time.
InSight places the exported file into the \INSIGHT\DATA\TXT directory on
disk unless you select another location.
Menu items that are not currently available are displayed in a ‘grayed-out’
manner (shown in light gray instead of black lettering). This denotes that either
the related option is not installed on this logger or that another menu choice
must be enabled first before using this item.
Note:
For both the InSight for DOS operating system and InSight for the Windows®
operating system versions of InSight, the Report Generation menu provides
extensive control over report generation, automatically generates a report text
file, and provides a print button presented on the created report screen. (See
heading: Report Generation.)
AS041 Rev. 10-1-99
InSight Data Analysis Software
14
The Site file name is used as the default name for the exported data. The
\INSIGHT\DATA\TXT is the default directory where the file is placed unless
you pick another name or location. The three letter file name extension defaults
to “.TXT”, as shown below. If you wish, you may enter a new file name and/or
select a different path (disk drive and/or directory) for the exported file.
Comma Delimited File Format
In this example we have elected not to include the Program Settings, Events or
Sample History. We only want to export the logged readings for use in a
spreadsheet. The example below shows the exported file if viewed with a word
processor:
"Date","Time","Rain (in.)","Level (in.)","Velocity (fps)","Channel 5
(volts)","Flow (gpm)"
"04/APR/96","13:05",0.00,5.070,1.88, 266.00
"04/APR/96","13:10",0.02,5.073,1.83, 259.02
"04/APR/96","13:15",0.00,5.077,1.87, 266.00
The “quotes” signify text fields. Entries without quotes signify numeric fields.
Each field is separated by a comma delimiter. The comma helps a spreadsheet
program determine how to place data into columns. Shown below is the same
file when opened with Microsoft Excel 5.0.

The Open selection from the Site menu provides several data analysis and
reporting functions. After selecting the desired file from the list, InSight opens
the Site Data Menu (below). Note that selecting the Site Files button from the
toolbar (shown above) is the same as opening the Site menu.
Site Information
The top section of the Site Data menu displays the logger program settings as
well as status information taken at the moment the data was retrieved:
Click on the desired button to show the associated information in the scrolling
text window to the right of the buttons.
AS041 Rev. 10-1-99
InSight Data Analysis Software

The choices are:
• Settings - list of programmed settings in the logger at time of data retrieval.
• Events - time and date stamped list of significant events occurring in the
logger (see Event Log in the Diagnostics section of the Remote
Programming chapter for details).
• Current Status - real-time ‘snapshot’ of all activity in the logger at the time
of data retrieval.
• General Info. - Software revisions and other pertinent information related to
this site file.
Graphs and Reports
The bottom half of the Analysis... menu is shown below. This is where you
generate tabular reports and graphs. Each choice is described in the following
section.
AS041 Rev. 10-1-99
InSight Data Analysis Software

Graph Data
The Graph Setup menu is shown below. The interface is similar to Windows®
notebook ‘tabs’ feature.
Plots Tab
Select up to two plots, plus
rainfall, from the pulldown lists of available
channels.
Enter your own scaling for
the graph or click here to
let InSight scale the graph
for you.
Select a graph type by
clicking here.
Click here to display
the graph.
Plot Selection
Select the channel of data for plot one and plot two. You may select Not
Displayed if you wish to hide one or both of the plotted lines. Rainfall is plotted
as a bar graph along the bottom of the graph screen and may be displayed or not
displayed.
Graph Scaling
InSight scales the Y-axis of the graph automatically if Auto-scale is selected.
When Auto-scale is not selected you may enter your own scaling in the boxes
provided for Minimum and Maximum. Rainfall is always auto-scaled.
The X-axis is scaled automatically to logical increments and initially displays
the entire data range but may be expanded and contracted while viewing the
graph.
Graph Types
InSight provides two graph styles, Line Plot and Scatter Plot.
Line Plots
Line plots provide a dynamic visual representation of your data. You may zoom
in for a closer look, and pan forward or backward in time to locate the
information you need.

Channels Tab
Rename the channels to
provide a better description.
Modify the Units for any of the
recorded channels from the
logger.
Units
The ‘Units’ pull down windows allow you to modify the units for each available
channel to suit your needs. Click the arrow and select the desired unit from the
list. This allows you to record the data using one format and display it using a
different unit. After exiting and returning to the file at a later date, the units will
be reset to their original settings as recorded by the logger as a default starting
point.
Labels
The ‘labels’ column allow you to rename the recorded channel from the
instrument to more descriptive name. Notice above that Channel 5 has been
renamed to Battery which in this case makes more sense for reporting and
graphing purposes. Once the channels have been renamed, they remain renamed
until changed at a later date by the user.

Scatter Plot
Scatter plots are an important component of flow survey data analysis. They
provide a feel for the accuracy of the data by assessing the performance of the
logger and the suitability of the flow monitoring site. Careful analysis of scatter
plots (which is beyond the scope of this manual) yields a wealth of information
about the effects of overflows, backwater conditions and tidal influences on the
flows in sewers. The example below illustrates a typical scatter plot of level (yaxis) vs. Velocity (x-axis).
Scatter plots must contain at least two channels of data (typically Level vs.
Velocity). Scaling is automatic and all available data is used when generating a
scatter plot.

Printing Graphs
For InSight for the DOS operating system and InSight for the Windows®
operating system versions of InSight, printing an InSight graph to a printer or
plotter consists of selecting the Print button at the top of the graph window.
This opens a Print menu. The print menu presented differs between two versions
of InSight as indicated below.
Print Screens — InSight for DOS operating system (Only)
In the DOS-based version of InSight, the Print button presents the printer
configuration menu shown below. The DOS-based print function requires that a
printer is connected to the parallel or serial port of the PC and provides options
for selecting the port and, in the case of the serial port, its configuration. The
user must select from an extensive, yet limited, list of printer types (drivers). In
the somewhat rare event that the printer or emulation the user desires is not
listed, and additional “Print to file” capability can be selected. (See heading:
Printing Graph to File.)

Averaging Interval
Select an interval for your data to be averaged across. For instance, you may
record your data in one minute increments in the logger but that would display
1440 lines of logged readings on your report should you choose to include them.
An alternative to that would be to select perhaps a sixty minute averaging
interval to condense the displayed readings. Each one minute recorded reading
would be averaged for each sixty minute interval and displayed as a single
reading for that hour thus giving you only 24 logged readings for a day report.
This allows you to record the data at a higher resolution for accuracy without
printing sheet after sheet of recorded data in your report.
Average Forward / Backward
Select whether to average your readings forward or backward. The direction
chosen governs whether the readings recorded before or after the averaging
interval will be used to calculate that specific averaging point.. Consider this
example, if you recorded data in one minute increments, and selected a fifteen
minute averaging interval, the following would occur depending on choice:
• Averaged Forward : Data is averaged on even increments per hour, 12:15,
12:30, 12:45 etc.…The data points recorded between 12:01 and 12:15
would be averaged and the result would be used to signify the 12:00
reading. Readings recorded from 12:16 to 12:30 would be averaged and the
result would be used to signify the 12:15 reading and so on.
• Averaged Backward : Data is averaged on even increments per hour, 12:15,
12:30, 12:45 etc.…The data points recorded between 12:01 and 12:15
would be averaged and the result would be used to signify the 12:15
reading. Readings recorded from 12:16 to 12:30 would be averaged and the
result would be used to signify the 12:30 reading and so on.
Start of Day / End of Day
The definition of a ‘day’ can now be defined by the user. If your usual reporting
period consists of your shift, for instance, you can tell InSight to only report on
data within that period. For example, the start of day could be 8am and the end
of day could be 5pm. In this case, any data from 5:01pm to 7:59am will be
ignored and excluded from the report.
Note : The period of time chosen for the ‘End of Day’ cannot be past
midnight of the current day. In other words, a day cannot be defined as 8am
to 8am for example. 8am to 11:30pm would be acceptable.

• Enter the desired value to add, subtract or replace the data in the selected
range.
• Select the desired time / date range to apply your edits to.
• Select the Add, Subtract or Set button or press Cancel to quit without
making any changes.
How Flow Calculations are Performed
Flows are calculated each time a report or graph is created. Therefore, if you
edit a level or velocity file and then create a report or view a graph of the edited
flow data, then the flow data is recalculated to reflect edits you made.
How Changes to a Logger Program Affect Merged Database Files.
If you make a programming change in the logger (other then those affecting the
data logging channels) then merge this new data with a previously stored
database, only the program settings from the most recent merged file apply to
the database.

Security Function
American Sigma loggers which have a password security function (see list
below) execute a security sequence whenever a connection is initiated with the
logger. How or whether the user is allowed access to a fully functional
“Connected to (logger name)” menu screen is determined by the security status
(secured or unsecured) of the meter and other factors as described in the
paragraphs which follow.
Password Security Connect Operations
Operations under this heading assume the use of the current password-capable
versions of InSight and logger. For information on various combinations of
password capable and nonpassword-capable versions of InSight and loggers one
might encounter in the field, see the heading “Possible InSight - Logger
Combinations” at the end of this section.
After clicking OK in the “Connected To Logger” screen or clicking “DIAL
(F7)” button in “Connect Via Modem” screen, the security feature will function
as follows:
Unsecured Logger (Password disabled)
If the password of the logger was previously unsecured (disabled) via InSight,
InSight checks for the security status of the meter, verifies the unsecured state
and presents a fully functional “Connected To [logger]” screen.
Secured Logger (Password enabled)
If the password was previously secured (enabled) in InSight, InSight presents a
password entry screen with a blinking screen cursor in the password entry box.
Enter the eight-character numeric password and click OK. The password must
be eight numeric characters long ( no more, no less). A series of asterisks
display as the user enters the password numbers.
NOTE
The default password (as shipped from the factory) is eight zeros
(00000000). All loggers are shipped from the factory in the unsecured
condition, i.e., password entry not needed to connect with InSight
software. Only numeric characters (0 - 9) are acceptable.
The password entry screen which displays when a connection to InSight is
initiated with a secured logger is depicted below.
AS041 Rev. 10-1-99
InSight Data Analysis Software
46
Password Entry Results
Correct Password Entry
Entry of the correct password will present a fully functional “Connected To
[logger]” menu screen. This is the major menu screen from which interaction
with the logger in InSight is initiated. In addition to command buttons which
allow the user to Retrieve Logged Data, view Current Status, perform Remote
Programming and Diagnostics, a Security button is provided to allow the user to
enable or disable the password security and to change the password used. See
heading “SECURITY” latter in this manual for instructions on enabling,
disabling, and changing the password security of a logger.
CAUTION
If the connection to a secured (password-enabled) logger is broken
by any means other than the Return (disconnect) command in the
“Connected...” screen or completion of a Speed Group function, that
logger will remain UNsecured until communication is re-established
and the logger is Secured again.
Incorrect Password Entry
Entry of an incorrect password will cause the “Invalid Entry!” error screen to
display. Click OK to acknowledge the failed entry and present the password
entry screen again. After three incorrect password entries, InSight will present a
screen which shows an encrypted version of the password (see heading below).
Recovering Forgotten Password
If a password is lost or forgotten or a typographical error while setting the
password inadvertently creates an unknown password, the logger is not
hopelessly locked forever. A feature is provided which presents an encrypted
password anytime three incorrect passwords are entered one after another while
attempting to connect to the logger. An “Invalid Entry!” error screen follows
each entry. After the third “Invalid Entry!” error screen, the encrypted password
is displayed. This encrypted password is not useable as a password until
decrypted into a numerical password by American Sigma Technical Support
Department.
The procedure for recovering a password is as follows:
1) In the password entry screen enter an incorrect password (or nothing) in the
password entry box three times, each time clicking OK when the “Invalid
Entry!” error screen is displayed.
2) After the third entry, the encrypted password code is displayed. Call
American Sigma Technical Support and report the encrypted code.
3) Technical Support can decode the encrypted password readout and provide
the actual numerical password.

AS041 Rev. 10-1-99
InSight Data Analysis Software
52
Alarms
Alarms can be programmed to activate based on certain conditions (high water
level, low battery power, etc.). When an alarm is tripped an action is initiated
(report via modem, dial a pager, set a relay, or trigger a sampler).
There are two types of alarms:
• Channel Alarms
• System Alarms
Channel Alarms look for trip points to be reached (either high or low
or both) before initiating an action (Such as closing a relay when the
water level exceeds 24” or drops below 4").
System Alarms initiate an action when a trouble condition occurs.
(such as closing a relay when the memory is full).
Channel Alarms
Channel alarms may be configured for all available data channels. Channel
Alarms activate when a user definable high and\or low set point is reached.
Double-Click an
item to Modify it.
(or use the Tab
and Arrow keys
then the Space Bar
to select it)
To program a channel alarm you must:
1. Select the method of reporting the alarm. Alarms may be reported via
modem (pager) or relay contacts (if so equipped).
2. Map the alarm to the desired channel (level, flow, pH, etc.) and condition
(low, high, or rate of change).

Enter the desired set-point and deadband for the alarm condition. Note that
the units of measure shown reflect the settings you make in the Data Log
menu.
Enter the desired Deadband value (see Deadband, following this section,
for more details)
InSight Data Analysis Software
54
Deadband
After entering the set-point you may enter a "Deadband" value. This deadband
is the area between alarm "turn on" and "turn off". The purpose of setting a
Deadband is to eliminate alarm relay chatter which may occur if the turn-on and
turn-off values are too close together. Small fluctuations occurring when the
reading is at or near the trip point can toggle an alarm relay on and off very
rapidly.
Alarm ‘On’ at
7.00 pH
In the pH example below, the alarm is set to a 7.00 pH High Alarm and the
Deadband is set to .10 pH. When the pH reached 7.00 (upper dashed line), the
high pH alarm tripped, but the alarm did not turn back off until the pH fell
below 6.90 pH. This difference is the Deadband setting and should be set
according to the variation characteristics of the item being measured.
Alarm ‘Off’ at 6.9 pH
Deadband
Example of a HIGH 7.00 pH alarm with 0.10 pH deadband.
Multiple alarms may be enabled at one time. You may also assign individual
alarm conditions to individual relays or assign all alarms to the same relay.
Note: Rainfall and Flow Rate of Change alarms are HIGH set point
conditions; they take no deadband; and they are time dependent. You must
log rainfall to use an alarm on a rainfall condition; likewise, you must log
flow in order to implement an alarm on a flow rate of change.

System Alarms
To program a System Alarm you must check the box that corresponds to the
desired response to each alarm condition (see below). You may send the alarm
to a pager, via modem, or set one of four relays (depending on which options
are installed in the logger).

within the logger. This does not apply to your PC’s communication settings
which are set when connecting to a logger using InSight or other support
software.
When an alarm condition reports via modem there are two ways to deliver the
alarm message to the recipient:
• Direct Reporting to PC via modem.
• Pager Notification via pager service.

Tip: Modem Reporting
requires that the logger
be programmed to
report alarms via
modem.
Modem Reporting to a PC
Modem Reporting lets you set up your PC as a type of data logger ‘answering
machine’. The PC waits for a logger to call in via modem and report an alarm
condition. The PC displays the alarm message in the Modem Reporting window
before it hangs up the phone and waits for another logger to call in.
Check your modem settings before hitting the OK button below.
Once the OK button is pressed, the modem is set to answer incoming calls.
Each alarm message is displayed in a scrolling window as shown below.
At any time you may Print or Save to disk the contents of the modem reporting
window.
Use this feature to check on alarm conditions that occurred overnight or when
you are away from your desk.
AS041 Rev. 10-1-99
InSight Data Analysis Software

Pager Reporting
The pager is implemented by using the modem, so the setup of the pager is done
through the setup of the modem. Pager reporting utilizes the industry standard
TAP protocol (Telelocator Alphanumeric Protocol) to deliver information to up
to three alphanumeric pagers. The logger dials your paging service provider
and passes the alarm code, site ID and up to three pager phone numbers to the
service provider’s PC automatically. The service provider’s PC then sends the
alarm code and site ID to all enabled pagers.
Alarm Code, Site ID,
and up to 3 pager #’s

Up to 3
Pagers
To enable the pager option:
1. Enter the phone number of the paging service provider.
2. Enter how many pagers you wish to call when an alarm occurs. The data
logger supports up to 3 pagers.
3. Enter up to three pager phone numbers.
NOTE: When contracting with your local pager service provider you must let
them know that the SIGMA loggers conform to the “TAP” paging standard.
With this information they will be able to configure their equipment to work
with the SIGMA logger.
When the logger calls the paging service during an alarm condition, it will
include in the transmission a Pager Alarm Code number which corresponds to a
specific alarm condition (see chart on the following page).

Data Log
SIGMA data logger’s can record more than 100,000 readings taken from
multiple sensors and other data channels and store them in solid state, battery
backed memory for later viewing and retrieval.
From this menu you may select the input channels you wish to log, how often
you want them logged (logging interval), units of measure, and how to treat the
memory when it becomes full (slate or wrap).
Note: The Data Log menu style may vary depending on the model of the data
logger to which you are connected.

Memory Setup
Click on the radio button that corresponds to the desired memory mode.
Memory can be configured in one of two ways, Slate or Wrap.
Slate Memory Mode
Slate Memory Mode causes logging to stop when memory becomes full. The
flow meter continues to operate but no additional data is logged. This mode is
best if you don't want to discard any of the logged data from the beginning of
the logging period.
Wrap memory mode
Wrap mode removes old data and recycles the memory for reuse. This means
that when memory becomes full, the oldest reading is discarded each time a new
reading is taken in. When memory becomes full, the flow meter continues to
operate AND log data. This mode is best if you are interested in the most recent
data.

Flow Setup
Flow Units
Select the desired flow rate unit of measure from the pull-down list.
Total Flow Units
Select the desired unit of measure for total flow from the pull-down list. The
flow totalizer is a series of up to three numeric counters in the 900\950\960\970
loggers which display the total flow being measured by the flow meter. All
software totalizers are set to zero upon program start and all share the same unit
of measure and scaling factor.
Totalizer Scaling
Select the desired scaling for the internal flow totalizers from the pull-down list.
Scaling multipliers are provided to allow you to tailor the totalizer response to
meet the requirements of the application. High flow rates may require an
increased scaling factor if the totalizer increments at an unreasonably high rate
during peak flow periods.
Interval - Single (904\910\920\930\940 only)
Select the desired interval between data readings from the pull-down list. These
loggers wake up once per interval, take a reading of each channel, store those
readings in memory , then go back to sleep until the next interval. This method
provides the best battery performance and longest memory capacity when used
with longer intervals (greater than 10 minutes).
Interval - Multiple (900\950\960\970 only)
InSight supports the use of multiple recording intervals for these loggers. Select
the desired interval for each channel from the pull down lists.
Extended Power (900\950\960 only)
If Extended Power is enabled, you must also select the desired logging interval
from the pull-down list. If Extended Power is not enabled then you may select
individual logging intervals for each channel.
Extended Power Enabled (900\950\960 only)
With Extended Power enabled, these loggers wake up once per interval, take a
reading of each channel, store those readings in memory, then go back to sleep
until the next interval.
AS041 Rev. 10-1-99
InSight Data Analysis Software
62
Extended Power Disabled (900\950\960 only)
With Extended Power disabled , these loggers wake up once per minute, take a
reading of each channel, store those readings in memory , then go back to sleep
until the next minute. Once per interval all stored readings are averaged or
summed and stored in memory. Longer intervals in this mode provide greater
memory storage but do not help much in conserving battery power.
A\C Power Considerations (900\950\960\970 only)
If an A\C power supply is installed, these loggers stay awake at all times, taking
readings approximately every second and logging an average every minute in a
temporary area of memory. At the end of the logging interval, the minute by
minute readings are then averaged over the period of the recording interval and
stored in memory. This mode provides the fastest response to quickly changing
events in the flow stream especially when output signals from the logger are
controlling external devices (4-20mA current loop for example).
Logging Intervals and Logger Memory
Longer logging intervals means longer total recording time is available. It also
means lower resolution since more averaging is done at higher logging intervals.
The key is to pick the shortest logging interval possible while still making data
collection convenient. If you can only get to the site once per month to collect
data, then you should pick a logging interval which almost fills memory over
the course of one month.
For example: If the logger is equipped with 128K of RAM memory and only
one channel is logged, then a 2 minute logging interval would take 24 days to
completely fill the available memory (see chart below). If, on the other hand,
you were to pick a 1 minute logging interval, the memory would become full
after 12 days.
Note: The 900\910\950\960\970 loggers have 128K of RAM standard and
512K as an option. The 920\930\940 loggers all come with 512K of RAM. See
904’s manual for similar table data.

Inputs
Each input may be logged or not logged. You may also select the unit of
measure and the logging interval for each input.
Level \ Flow Logging (900MAX\950\960\970 only)
Level and Flow are considered a single input channel. The flow values are
calculated whenever they are requested for display. The flow logging interval
applies whenever flow is displayed. The logging interval is always the same for
level and flow.
Analog Inputs (900MAX\950\960\970 only)
The configuration for these inputs requires on-site connection of a DC voltage
or current meter for proper setup. Configuration must be performed using the
front panel controls of the logger. No provision has been made in InSight
software for remote setup of these channels. Refer to the Operating and
Maintenance manual for your 900MAX Sampler or 950\960\970 Flow Meter for
details.

Level Sensor (910\920\930\940)
Loggers that support multiple concurrent sensors (920\930\940) require that you
designate one of the sensors as the Level 1 Sensor. If you only use one sensor,
you must designate it as the ‘Level 1Sensor’. If you use two sensors, designate
one as Level 1 and the other as Level 2.
Designate the first level sensor
as ‘Level 1’.
(Make sure the matching
velocity sensor is also selected
as the Velocity 1, if used).
Designate any remaining
sensors as Level 2 and Level 3.
Level Sensor menu (typical) for SIGMA 910\920\930\940 data loggers.
With a secondary sensor installed as a backup (in the unlikely event that a
primary sensor fails while in service), it is a simple matter to swap the
secondary sensor in place of the failed one without removing the logger from
the manhole. This could eliminate any unnecessary (and expensive) confined
space entry.

Designate the sensor priority from the pull-down list for each available sensor.
Note: The Level Sensor menu style may vary depending on the model of the
data logger to which you are connected. If only one level sensor is installed in
the logger it is automatically designated Level 1.

Deadband
For ultrasonic sensors you must also select a deadband value. Typically,
deadband is the minimum distance from the ultrasonic sensor to the target.
SIGMA data loggers are equipped with an adjustable deadband feature to help
prevent false echoes from tops of channel walls, ladder rungs, shelves, etc. (see
drawing below). A user selectable range is defined which is invisible to the
flow meter. Only objects beyond the deadband value can be detected.

(set to ignore the tops of channel walls)
Note: Care must be taken not to extend the deadband to where it meets or
overlaps the highest expected level in the channel. Whenever possible, a gap
of at least 2” (5.08 cm) should be left between the invisible range and the
highest expected water level.
Important: The adjustable deadband distance must be greater than the
minimum deadband of the sensor (See chart below).

The SIGMA 900, 950 and 960 loggers are available with several level sensor
options (bubbler, submerged probe, ultrasonic, all three), however these loggers
can only use one level sensor at a time.
Level Sensor menu for SIGMA 950\960 data loggers
From this menu you may configure the current level sensor for your

Bubbler (950 only)
• Bubble Rate - select the bubble rate from a scale of 0-10 that represents
approximately 1-5 bubbles per second. One bubble per second is
usually sufficient and saves battery life with fewer compressor cycles.
• You may also enable an optional Air Purge of the bubbler line on a
regular basis to help keep the end of the bubble tube free of silt or other
buildup. Keep in mind that air purges will reduce battery life for
loggers running on DC power.
Ultrasonic - enter the desired deadband. This must be equal to or greater
than the sensor minimum deadband (see chart above).
Submerged Transducer - Enter the sensor orientation (for when the sensor
is installed), either horizontal or vertical.

and/or modify it.
Primary device setup includes:
• Area-velocity - pipe diameter and unit of measure.
• Flumes - flume size.
• Manning Equation - conduit size, slope, roughness and unit of measure.
• None (level only) - No primary device installed. Flow is not displayed or
logged.
• Nozzle (California Pipe) - nozzle size.
• Power Equation (Q = K1Hn1 ± K2Hn2 ) - user entered variables K1, K2, n1,
n2
• Head vs. Flow Table - User entered look up table of up to 100 pairs of head
and flow values.
• Level vs. Area Table - User entered look up table of up to 100 pairs of level
and area values.

Head\Flow and Level\Area Tables require you to enter a ‘look-up’ table (shown
below). The logger directly measures the value in the left column and looks up
the associated value in the right column of the table. Values falling in-between
the data in the table are interpolated by the logger automatically.
In the Head\Flow table example below, the level reading of 1.5 inches (half way
between 1 and 2 inches) would return a flow value of 7.5 GPM (half way
between 5 and 10 gpm).
Click the Modify button (above) to enter or make changes to the Head\Flow
table (shown below).
Click the Next button after each pair of points has been entered. Select Done

Sampler Pacing
Sampler pacing provides a flow-proportional pulse output signal to an external
wastewater sampler such as a SIGMA 900 Sampler. This option requires
connection of a cable between the loggers ‘Sampler’ receptacle and a
wastewater sampler. Typically this is done by enabling the ‘external level
control’ feature on the sampler. See your logger and sampler manuals for
details concerning signal descriptions and cables.
When the Sampler Pacing signal is enabled you must select a trigger value and
flow unit of measure.
Note: For Sampler Pacing you must also program the sampler to accept an
‘External’ flow signal interval (see your sampler manual for details).

Site Description
The Site Description helps you to identify your data by entering a description of
the site and an identification number. These items are used to identify a specific
logger with a specific site. InSight and VISION software utilize this information
to automatically place data into the proper database during data retrieval.
Note: It is important that you give each logger a site ID number that is
unique to each site so that InSight and\or VISION software can place new
data with previously stored data automatically in the PC database.

Stormwater
The Stormwater menu shown below lets you start an attached wastewater
sampler when the trigger values have been reached. This feature is designed to
assist you in conforming to the EPA’s NPDES (National Pollutant Discharge
Elimination System) permit program. When the trigger values are reached a
signal is sent to an attached wastewater sampler telling it to start its sampling
program.
This option requires connection of a cable between the loggers ‘Sampler’
receptacle and a wastewater sampler. Typically this is done by enabling the
‘external level control’ feature on the sampler. See your logger and sampler
manuals for details concerning signal descriptions and cables.
Note: For Stormwater you must connect the logger to an external
wastewater sampler programmed to accept a ‘level-start’ signal (see your
sampler manual for details).
AS041 Rev. 10-1-99

74
Velocity Sensor
Loggers that support multiple concurrent sensors (920\930\940) require that you
designate one of the sensors as Velocity 1. If you only use one sensor, you must
designate it as ‘Velocity 1’. If you use two sensors, designate one as the
Velocity 1 and the other as Velocity 2.
Designate the first and secondary sensors from the pull-down lists for each
available sensor (shown below).
Designate the first velocity
sensor as Velocity 1
(Make sure the matching
level sensor is also selected
as Level 1, if used).
Designate any remaining
sensors as Velocity 2 and
Velocity 3.
With a secondary sensor installed as a backup (in the unlikely event that a
primary sensor fails while in service), it is a simple matter to swap another
sensor in place of the failed one without removing the logger from the manhole.
This could eliminate any unnecessary (and expensive) confined space entry.
Note: The Velocity Sensor menu style may vary depending on the model of the
data logger to which you are connected. If only one velocity sensor is
installed in the logger it is automatically designated as the Primary Sensor.
Overcoming Site Problems
Some sites may be difficult to monitor due to poor site conditions (see your
logger manual for details). The direction, as well as the speed of the particles in
the flow stream contribute to the signal received by the velocity sensor. If
turbulence near the measurement point is excessive, it may be difficult for the
sensor to determine the average velocity of the stream. SIGMA loggers provide
several unique features to help deal with these problem sites.
Velocity Direction.
There are three choices:
• Upstream (normal)
• Downstream
• Always Positive
AS041 Rev. 10-1-99
InSight Data Analysis Software
75
Upstream (normal)
This choice is for average sites with fairly consistent velocities, and low to
medium turbulence. The flow stream should ideally travel relatively straight
through the site with no drops or turns near the measurement point. Mount the
sensor in the pipe, facing into the flow, where the flow stream enters the
measurement area.
Downstream
This choice allows you to locate the sensor on the downstream side of the
measurement point (where the flow stream exits the site), aiming the sensor in
the downstream direction rather than the normal, upstream direction. This
option is useful in sites where there is more than a single flow stream entering a
site and it is desired to measure the combined flow of all streams at a single exit
point.
AS041 Rev. 10-1-99
InSight Data Analysis Software
76
Mounting the sensor ‘backwards’ in this manner (see below) causes the velocity
direction readings to be the opposite of actual stream flow. By selecting the
Downstream choice, the logger electronically reverses the measured signal to
show actual flow direction.
Always Positive
Extreme turbulence conditions can make it difficult to detect proper flow
direction due to the mixing action of very turbulent water. Reflecting particles
in the flow stream (particularly near the surface of the stream) may be traveling
in several different directions at once, even though the bulk of the stream is
moving in the same general direction. The velocity magnitude is generally
consistent in these cases, however reflections coming from the particles moving
in a positive direction (same direction as the flow stream), are so mixed up with
those coming from particles moving in a negative direction (opposite direction
as flow stream) that determining actual direction is difficult.
Note: selecting Always Positive, causes all readings to be logged as positive,
regardless of the measured signal direction. This choice should not be
selected for sites where negative flows normally occur, such as with tidal
effects on ocean outfalls.
AS041 Rev. 10-1-99
InSight Data Analysis Software
77
Velocity Cutoff \ Velocity Default
Velocity Cutoff compensates for difficulty encountered at sites with very low
velocities and extremely clean water. This combination of unique conditions is
difficult because; the clean water may contain very few reflecting particles, and
extremely low velocities usually mean little or no turbulence to add entrained air
bubbles to the flow stream (which also make good reflecting targets).
Rather than report erratic velocities, the Velocity Cutoff allows you to enter a
default velocity value which is used when the Velocity Cutoff set-point is
reached. The logger holds the default value whenever the velocity is at or below
the cutoff value.
Velocity Signal Strength
The velocity probe must be installed in the flow stream and be connected to the
logger in order for this diagnostic to work. Velocity signal strength allows you
to view a ‘real time’ signal directly from the velocity probe. It shows you the
current velocity Signal Strength (percentage of Doppler signal returning to the
probe). Use this diagnostic to determine whether or not you have the probe
mounted for optimal velocity measurement. The closer to 100% the Signal
Strength is, the more stable the velocity reading will be. If the signal is lower
then 50% it may be due to improper installation of the probe or lack of
particulate in the flow stream to reflect the Doppler Signal.
See your logger manual for details on proper site selection and sensor
installation.

Set Time & Date
This operation lets you set the real-time clock in the logger. You may set the
clock to any time you wish or you may automatically synchronize the loggers
clock with the clock in the your computer.
Note that this operation causes all logged data points to be permanently
cleared from the logger memory. Make sure you download the logged data
before proceeding.
Enter the new logger time and date or let InSight use the time from the PC. The
current time and date from the logger and your PC are displayed for your
reference (see below).
Select the Program button to place the new time and date into the logger, or
press Cancel to abort the process. Logged data is not cleared if the Cancel
button is selected.

Toggle Sample Enable Line
This choice lets you toggle (enable) the Sampler Start signal in the logger. This
signal appears on Pin D of the Sampler receptacle. It is used to enable a
sampling program on a Sigma wastewater sampler or equivalent.
This line is normally allowed to float and is switched to ground for 65 seconds
when toggled.
Calibrate Level
Level calibration procedures in this section pertain to the SIGMA 904, 910, 920,
930 and 940 loggers only. Level sensor calibration for the SIGMA 900MAX,
950 960, and 970 are performed via the front panel of the logger. See the
appropriate logger manual for complete calibration instructions.
Note: Previous calibration adjustments are discarded by the logger each
time a calibration is started. Do not return to this screen to check the
calibration, instead use the status screen to display real-time values from
the sensor.
Submerged Velocity Probe Level Calibration
Submerged Velocity Probe calibration requires a bucket with at least six inches
(16 cm) of water and a ruler.
Calibration of the submerged velocity probe characterizes the logger electronics
to the unique characteristics of each individual probe. In addition, the
calibration compensates for any drift in the output of the sensor which may
occur over long periods of time as the materials in the sensor age (one year or
greater).
The submerged velocity probe is a pressure transducer containing a stainless
steel diaphragm. As the water pressure increases, (with increasing head in the
flow stream) the diaphragm is deflected, or pushed, against a solid state device
called a strain gauge. The strain gauge converts the pressure against the
diaphragm to a voltage. As the head (level) in the flow stream increases so does
the voltage coming from the submerged velocity probe. The voltage is read by
the microprocessor in the logger at a regular interval and is converted to a
number which represents the level in the flow stream. The level reading can
then be converted by the logger to a flow rate based on a primary device
formula or readings of the velocity circuitry.
To assure optimum accuracy, re-calibration should be performed approximately
once per year, when changing to a different submerged velocity probe or when
changing a probe to a different flow meter.

face down on a
flat surface
then press OK
Step 2 - Remove Air Bubbles
Place the probe upside down in the bucket of water and tap gently to remove
any air bubbles from under the plate. If these bubbles are not removed you may
receive false readings from the sensor during calibration.

Step 3 - Submerge Probe To A Known Depth
Place the probe under at least six inches (16 cm) of water in a horizontal
orientation, as shown below. Make sure the water surface is calm and the probe
is stable and not moving around. Then press OK to continue.

Measure the depth of water from the bottom of the bucket to the surface of the
water (‘D’ above) and enter the new value ( as shown below). Click on the
Enter New Value box, then enter the new value. The real-time reading from the
sensor is displayed on top for reference. Press the OK key to continue.
This completes the calibration of the Submerged Velocity Probe.
Note: Always adjust the level reading when re-installing the flow meter
following a calibration.

83
Ultrasonic Level Calibration
Level calibration procedures in this section pertain to the SIGMA 910, 920, 930
and 940 loggers only. Level sensor calibration for the SIGMA 900MAX, 950
960, and 970 are performed via the front panel of the logger. See the manual
for your 900MAX, 950 or 960\970 for complete calibration instructions.
Note: Previous calibration adjustments are discarded by the logger each
time a calibration is started. Do not return to this screen to check the
calibration, instead use the status screen to display real-time values from
the sensor.
Calibration should be performed each time the sensor is installed at a new site or
whenever a sensor is moved to a different logger. Calibration of the ultrasonic
sensor includes calibrating the temperature probe inside the sensor body. From
this menu you may also match the current ultrasonic sensor reading to the water
level in the flow stream using one of two methods, Liquid Depth or Sensor
Height, which are described in the following section.
Enter the new temperature value in the box provided (in degrees Celsius) by
clicking on the Enter New Value box and typing (see important note below).
Note: Temperature Time Constant
The speed of sound in air varies with the temperature of the air. The
ultrasonic sensor is equipped with temperature compensation to help
eliminate the effects of temperature variation under normal site conditions.
The time constant of the ultrasonic transducer is 100 minutes. The
transducer temperature must be equal to the ambient air temperature at
the site prior to calibration for optimum results. The sensor takes one
AS041 Rev. 10-1-99
InSight Data Analysis Software
84
hundred minutes to come to total equilibrium with the surrounding air
temperature.
Level calibration requires entry of either the liquid depth or the sensor height.
Each method has it’s advantages and disadvantages so selection of the proper
method will depend upon the site conditions.
Liquid Depth
This choice requires you to enter the water level or depth of liquid which is
contributing to flow. In a round pipe the entire depth typically contributes to
flow. In a weir, only the depth which is flowing over the weir plate contributes
to flow. Note: This is the same as using the Level Adjust choice in the
Remote Programming menu.
Liquid Depth calibration is only used when:
1. There is access to the primary device for a physical measurement of the
liquid depth, AND,
2. Water is flowing during installation of the flow meter (channel is not dry).
Selecting the Liquid Depth method will prompt you to make sure the sensor has
stabilized for at least two minutes before entering the new water level.
The Level Adjust menu (below) displays the current level reading in the top of
the window for your reference. Enter the new level in the box provided at the
bottom of the window.

value (make sure you enter the value in the units shown). Press the OK button
when done or Cancel to abort the process.
Sensor Height
This choice requires you to enter the distance between the face of the ultrasonic
sensor and the zero flow point in the primary device. The zero flow point in a
primary device is the level at which flow ceases. In a round pipe the zero flow
point would typically be the invert or bottom of the pipe. In a V-notch weir the
zero flow point would correspond to when the liquid behind the weir is level
with the bottom of the ‘V’ (There would still be liquid behind the weir plate but
it would not be contributing to flow).
Sensor Height calibration is used when:
1. Access to the primary device is difficult (such as confined space entry in a
manhole), or
2. When there is no liquid flowing during installation of the flow meter (the
channel is dry).
Selecting Sensor Height prompts you to enter the distance from the face of the
transducer to the zero flow point of the primary device. In a dry pipe the zero
flow distance is the distance from the face of the sensor to the bottom of the
pipe.
The current distance to the nearest target (Liquid Distance) is shown at the top
of the window for your reference. Enter the new Zero Flow Distance in the box
provided.
Note: Always re-check the Level Adjust when re-installing the flow meter
following a calibration.

Adjust Level
Setting the Water Level
Take a physical measurement of the water level and enter the new level number
using the Level Adjust menu shown above. The Current Level reading is
downloaded from the logger and displayed every few seconds for your reference
(menu controls are disabled during this period of time).
To set the water level, measure from the surface of the water to the top of the
pipe (‘A’ in Drawing above), then subtract this from the pipe diameter (‘B’ in
Drawing) to get the water level in the pipe (‘C’ in Drawing).
This method causes no disturbance to the flow stream which might otherwise
effect the measurement (and it keeps the tape measure or ruler out of the “stuff”
where it will stay clean).
Repeat this procedure for all installed level sensors.

DTUs and Password Security
As indicated in the screen above, any logger which has been secured (locked)
with a password cannot transfer data to a DTU until the logger is unsecured via
InSight. During an attempt to download data to a DTU from a password-locked
logger, ERROR 52 Code may display on the DTU. In this instance, the code
merely indicates a password-secured logger rather than a “flash memory
corruption” usually associated with this error code. DTUs, themselves, cannot
be locked (secured) with a password.
Unsecure Logger
Clicking the Unsecure Logger button will present a brief “Checking Security
Clearance” message and then the “Connected to... [logger]” screen. The logger
is now unsecured and will not require a password entry to access the
“Connected to...” screen the next time a connection is initiated in InSight.

Connected to a Rain Logger
The Rain Logger is a battery powered solid state data logger that is used in
conjunction with an AMERICAN SIGMA Tipping Bucket Data Logging Rain
Gauge. When mated with a SIGMA Rain Reader, the Rain Logger transfers
data optically into the Rain Reader and simultaneously via RS232 cable into
your PC.
Note: This battery is for
temporary use in the
field to power the Rain
Reader when A/C power
is not available (when
using a laptop computer
for example). Always
disconnect this battery
when not in use to
conserve battery life.
To connect a Rain Logger to your PC:
1. Install the Rain Reader and Rain Logger into the alignment tray as shown
above.
2. Connect the A\C wall mount power supply to the Rain Reader (or use the
temporary 9 volt battery if A\C power is not available).
3. Connect the Rain Reader RS232 cable to your PC’s COM port.
4. Select the proper COM port for use with your PC (shown below). Note: the
Rain Logger baud rate is permanently set to 4800 baud and so the baud rate

SCHEDULING
The Scheduling function in the Advanced menu allows a user to schedule when
InSight will call a specific logger at a specific phone number at a specific time
and day of the week and download the data from the logger. The logger being
called must have a modem installed. Moreover, InSight must remain running on
the PC after the Begin button is clicked.
The number of meters that may be scheduled at one time depends on the total
time required to collect data from each meter and the frequency of data retrieval.
There is no limit within InSight on the number of scheduled retrievals.
Click once on an
item to delete it
from the schedule.

Scheduling and Security
When a user adds a logger to the schedule via the “Add” button and screen (see
below), a text box is provided on that screen for entering the password which
was set for the particular logger. The user must know and enter the password
for each logger being scheduled.
If a particular logger is not password secured (locked), do not enter anything in
the password text box.

scheduling entry.
If a password for a (secured) logger was not entered or entered incorrectly in the
Scheduling Add screen, an error code similar to the screen depicted below will
display when the logger is called and the connection prevented by the password
security feature. The incorrect password that the logger received is listed
between the parentheses at the end of the error code. If no password was

ARCHIVING DATA
Archiving creates a spare copy of your data for use in the event of failure or
loss of the original. This essential precaution is often neglected by computer
users until the first time they experience a disk crash or accidentally delete the
only copy of the file they have been working on for the last six months.
STORE ARCHIVED DATA OFF-SITE
Ideally the backup copies should be kept at a different site or in a fire safe since,
though your hardware may be insured against fire, the data on it is almost
certainly not insured and not easily replaced.
INCREMENTAL BACKUP
A copy of all files which have changed since the date of some previous backup
is called an Incremental Backup. The first backup of your data should include
all files. Call this level 1. The next backup, level 2, would include only those
files which have changed since the level 1 backup. Together the level 1 and
level 2 backups will include the latest version of every file. Level 2 backups are
also considerably less time consuming since they contain fewer files.
BACKUP DEVICES AND PROCEDURES
Backup device technology changes rapidly. Choices include floppy disk, tape
cartridge, optical disk, recordable CD ROM, etc. Consult your computer vendor
for the best backup solution for you. Your backup software includes valuable
tips on procedures for archiving files.
The important thing is to have at least one spare copy of all your important data.
Hard disk drives all crash eventually, but even more common is accidentally
deleting that file you worked on for the last six months. Be prepared and you’ll
be back to work in no time.

If you have trouble transferring data from a logger, go through the following
checklist to find the source of the problem:
1. Make sure you are using the correct cable. Remove all adapters and
extension cables and try again.
2. Make sure the logger is turned on and has sufficient power.
3. Double check that the baud rates of the logger, PC and\or DTU all match.
4. Try a different COM port (since they are seldom labeled it can be difficult
to tell which COM port is which sometimes).
5. Quit Windows® if it is running and try again from the DOS prompt. Do not
click on a DOS icon to get to DOS, make sure Windows® is completely
closed.
6. If you have an older PC, lower the BAUD rate on the PC and on the logger
and try again (see COM Ports and UARTS below for details).
7. If your PC uses power management use LAPTOP.BAT to start InSight (see
Power Management below for details).
8. “Boot Clean” and try again (see Booting Clean below for details).
9. Try a different logger, if possible, to see if the problem resides in the
logger.
10. Try a different PC, if possible, to see if the problem resides in the computer.
11. Make sure you are using the latest versions of software. Visit the American
Sigma Internet Home Page (www.americansigma.com) or BBS (716-7981216) for the latest updates. Contact the factory for details.
BOOTING CLEAN — INSIGHT FOR THE WINDOWS® OPERATING
SYSTEM (ONLY)
To boot clean means to start the computer without loading the system startup
files AUTOEXEC.BAT and CONFIG.SYS. Since these files often load mouse,
network, CDROM, and other driver software, these options will not be available
when you boot clean. If one of these drivers is interfering with the operation of
InSight then booting clean will allow InSight to work correctly. Once you
determine if booting clean corrects your problem then you should contact your
PC administrator for details on modifying the startup files for compatibility with
InSight.

POWER MANAGEMENT — INSIGHT FOR THE DOS OPERATING
SYSTEM (ONLY)
Most laptop computers and many newer desktop computers have power
management features that conserve battery power and save energy. In some
cases this power management software interrupts the operation of DOS based
programs which use the PC’s COM port.
If you have trouble transferring data using a PC with power management then
you should start InSight by using the LAPTOP.BAT file instead of the
INSIGHT.EXE file as in the following procedure:
To start InSight from DOS:
1. Change to the C:\INSIGHT directory by typing CD\INSIGHT at the C:>
prompt (Note: this assumes you installed the program into the C:\INSIGHT
directory. If not, then substitute the appropriate drive letter and directory).
2. Type LAPTOP then press ENTER to start the program.
To start the program from Windows® 3.1 or 3.11:
1. From Windows® File Manager, select the FILE menu.
2. Click on the word RUN…
3. Type C:\INSIGHT\LAPTOP then click on OK to start the program.
To start the program from Windows® '95:
1. Click on the START button.
2. Click on RUN…
3. Type C:\INSIGHT\LAPTOP then click on OK to start the program.
This procedure temporarily disables all power management features in your PC
while InSight runs. Power management is then restored to its previous state
when you exit InSight.
COM PORTS AND UARTS
UART Chips. The heart of any serial port is the Universal Asynchronous
Receiver\Transmitter (UART) chip. This chip completely controls breaking the
native parallel data within the PC into serial format, and later converting serial
data back into the parallel format.
There are several different types of UART chips on the market. The original PC
and XT used the 8250 UART, which is still used in many low-price serial cards
on the market. In the PC\AT (or other systems based on at least an 80286), the
16450 UART is used. The only difference between these chips is their
suitability for high-speed communications. The 16450 is better suited for highspeed communications than the 8250; otherwise, both chips appear identical to
most software.
The 16550 UART was the first serial chip used in the PS\2 line. This chip could
function as the earlier 16450 and 8250 chips, but it also included a 16-byte
buffer which aided in faster communications. Unfortunately, the 16550 also
had a few bugs, particularly in the buffer area. These were corrected with the
release of the 16550A UART, which is used in all high-performance serial
ports.
Because the 16550A is a faster, more reliable chip than its predecessors, it is
best to look for serial ports that use it. If you are in doubt about which chip you
AS041 Rev. 10-1-99
InSight Data Analysis Software
111
have in your system, you can use the Microsoft MSD program (provided with
Windows® or DOS 6) to determine the type of UART you have.
How this relates to the SIGMA logger data transfer.
If you are having trouble downloading from a DTU-I and you are sure the COM
port setting is correct, (and if you are sure the COM port works at all) then try
downloading from the logger directly to a PC (PN1727 cable) using a slower
baud rate such as 4800 or 2400 (set BOTH the PC AND the logger to the same
baud rate). If this works OK then try increasing the baud rate back to 19,200
baud. If it fails at the higher baud rate then you need to upgrade your PC serial
port. Note that the age of the PC does not necessarily tell you if you have a
faster serial port UART. Many new PC’s still ship with the slower serial ports.
Use the MSD program to tell for sure.

The last version of the 8250 fixes bugs from the previous two versions. The interrupt
enable bug in the original 8250, expected by the PC and XT ROM BIOS software, has
been put back into this chip, making the 8250B the most desirable chip for any nonAT serial port application. The 8250B chip may work in an AT under DOS, but does
not run properly at 9600 bps.
16450
IBM selected the higher-speed version of the 8250 for the AT. Because this chip has
fixed the interrupt enable bug mentioned earlier, the 16450 does not operate properly
in many PC or XT systems, because they expect this bug to be present. OS\2 requires
this chip as a minimum, or the serial ports will not function properly. It also adds a
scratch-pad register as the highest register. The 16450 is used primarily in AT
systems because of its increase in throughput over the 8250B.
16550A
This chip is a faster 16450 with a built-in 16-character Transmit and Receive FIFO
(first in, first out) buffer that works. It also allows multiple DMA channel access.
You should install this chip in your AT system serial port cards if you do any serious
communications at 9600 bps or higher. If your communications program makes use
of the FIFO, which most will today, it can greatly increase communications speed and
eliminate lost characters and data at the higher speeds.

SYNCHRONIZED TIME CLOCKS
It is important that the logger clock be set correctly and that it is in agreement
with the PC’s internal system clock. This makes comparison of data sets
consistent and more accurate. See Remote Programming \ Set Time and Date,
for details on synchronizing your PC clock with those in your data loggers.
Greenwich Mean Time (GMT)
Data readings are always taken with respect to time. Thus all observations have
a corresponding time, and that time is reported along with the measurement. By
convention, weather scientists use the twenty four hour clock, and use one time
zone, Greenwich Mean Time (GMT). This time is also known as Universal
Time (UTC). To convert to local time, we must know the time difference
between GMT and local time for both standard time and summertime (daylight
savings time). Not all states use daylight savings time in the summer.

Select COM Port
This selection box selects which serial COM port the PC
will use to connect to the meter. This is the COM port
the meter connects to via the RS-232 Safety Barrier.
Select Baud Rate
Sigma meters are shipped from the factory with the
baud rate set to 19, 200. This is also the default baud
rate setting of the utility.
If for any reason the meter’s baud rate was set to some
other baud rate with InSight® or VISION® software, the
utility software will not connect until the baud rate in
the utility is set to the same baud rate as the meter. A
dialog box will appear indicating an error, if a connection can not be established.
Available baud rates are 19200, 9600, 4800, 2400,
1200.
Get Current Modbus Address
Clicking this button retrieves the Modbus address that
is currently in the meter. If the utility software is not
communicating with the meter, “unknown” is displayed
in this box. If the address is changed in the Set Modbus Address box below it, the Get Current Address box
updates to display the new address.
Set Modbus Address
To change the meter’s Modbus address, enter the new
address in the Set Modbus Address box and click the
button above it.
Valid meter addresses are 0 to 247. Leading zeros are
not required for one- or two-digit numbers.
