LOGGING DATA MANAGER (CL520-LGM)
The CL520-LGM (LOGMAN) program is used to manage the data coming from the CL520 series memory. The data can
be viewed, saved on disk, printed and exported to be used with the most common spreadsheets.
The program presents a list of options selectable in a simple way, by pressing the appropriate number on the keyboard.
Also those who are not familiar with personal computer will find the use of this program easily achievable
When using the program, the CL520 series has to be connected to the PC by a serial cable, supplied as a standard
accessory with the software package.
The communication port to be used is COM1. This port is generally located on the backside of the PC and it's marked
with a label.
If, for any reason, your hardware is different, and you find it difficult to identify the PORT, refer to the handbook of your
PC.
Type on DOS command line: LOGMAN/? in order to obtain info on how to modify hardware parameters.
In order to use LOGMAN from the supplied disk, you just need to:
a)
Insert the diskette in the disk unit.
b)
Select the disk unit (generally speaking, they are A or B)
c)
Type LOGMAN to execute the program.
2.1
Installation
OMEGA strongly recommends to copy LOGMAN on the hard disk to grant the user an higher speed and larger storage
memory. To set-up the computer for demo program run the following procedure:
Turn your computer “On” and create a new directory on your Hard disk:
C>MD LOGMAN
Enter in the new directory:
C>CD LOGMAN
Insert the disk into the floppy driver and copy programs in a new directory.
C>COPY A:LOGMAN.EXE
C>COPY A:*.LOG
C>COPY A:COURB.FON
Now you can run the program:
C>LOGMAN
2.2

This option allows to load data previously stored on disk. Only files with a .LOG suffix will be loaded, it won't be possible
to load .TXT files.
From the main menu, select “Load data from File” function pressing the <2> key. When this option has been selected, a
file name is asked; simply type in the name of the file where you stored the data and, by pressing <ENTER>, they will be
loaded.
NOTE:
2.3
TO LOAD A NEW FILE MEANS TO COMPLETELY DELETE THE ONE ALREADY PRESENT IN MEMORY, THEREFORE BE CAREFUL TO
SAVE IT BEFORE LOADING.
Display Data
This option allows to examine the logged data, whether they're coming from the CL520 series or from the disk. From the
main menu, select “Display data” function pressing the <3> key.
All the data will be displayed on the screen as it follows:

The calculation will be executed on the whole batch of data.
From the main menu, select “Display MIN, MAX and AVG values” function pressing the <4> key.
2.5
Save Data on Disk
This option allows to save the data in the memory of the instrument into a disk.
From the main menu, select “Save data to File” function pressing the <5> key.
The program will ask for a filename, to which the suffix .LOG will be coupled to identify it as a file that can be used by
LOGMAN.
8
If on the disk that filename is already existing, a warning message will appear asking if the existing file has to be deleted
or the filename has to be changed.
2.6
Saving Data in Paradox(TM) or Excel(TM) Formats
The options 6 and 7 allow to save data in formats different from the LOGMAN one.
The available formats are referred to the most common database and spreadsheet: PARADOX (BORLAND) and EXCEL
(MICROSOFT). With these packages it will be possible to manage the data in a really complete way.
The files will have a .TXT suffix that identifies them as text files.
NOTE: TO SAVE DATA IN THIS FORMAT DO NOT SUBSTITUTE THE .LOG FILES. THE .LOG DATA FILE SHOULD BE CREATED ANYWAY.
2.7
Data Printing
This option allows to obtain an hard copy of the data in memory on a printer. From the main menu, select “Print data”
function pressing the <8> key. When selected, the operator will be asked to set-up the printer for operation. When the
system is ready, data will be printed.
2.8

LINEARIZATION DATA MANAGER (CL520-SLS)
As the CL520 series doesn't cover the whole range of sensors (thermocouple or resistance thermometers), but the main
ones, OMEGA gives the user a possibility of creating its own sensor linearizations and to use them with the CL520
series.
With CL520-SLS (LINMAN) it is possible to enter °C/signal points for the thermocouples and °C/signal for the Rtd and
also is possible to enter eng. unit/signal points.
LINMAN will provide the linearization by interpolating the inserted points. In this way, downloading data into CL520
series, it will be possible, by selecting Pt X ot Tc X, to use the special linearized sensor both in simulation and
measurement.
The program structure is the same as LOGMAN, with a list of options that are enabled by pressing the appropriate
number on the keyboard.
Type LINMAN/? on DOS command line to obtain info on parameter modifying.
3.1
Installation
OMEGA strongly recommends to copy LOGMAN on the hard disk to grant the user an higher speed and larger storage
memory. To set-up the computer for demo program run the following procedure:
Turn your computer “On” and create a new directory on your Hard disk:
C>MD LINMAN
Enter in the new directory:
C>CD LINMAN
Insert the disk into the floppy driver and copy programs in a new directory.
C>COPY A:LINMAN.EXE
C>COPY A:*.LIN
Now you can run the program:
C>LINMAN
3.2
Create Linearization Data
This is the option that allows the user the creation of a dedicated linearization by typing some values that will be
interpolated by the software linearization polynoms.
11
The program will ask for some important pieces of information that will be used to define the kind of sensor to be
linearized:
NORMAL DATA or
R0, A, B, C constants:
This option chooses between entering known points (and this is valid both for Tc and
Rtd) or mathematical constants that will be used in the Rtd linearization polynoms.
When data entering has been selected, other information will be asked:
if the ‘constant’ option is selected, the R0, A, B and C values must be typed in; if the
‘normal data’ is the choice selected, then this procedure has to be followed.
When the “Create by normal data” is selected, the procedure will ask the following information:
Tc X or Rtd X:
This option is selected if the sensor to be linearized is a thermocouple or a resistance
thermometer. The difference is in the Rj compensation, that will be considered only for
the thermocouples.
NORMAL / SPECIAL:
If NORMAL is selected, the instrument will use the linearization in a normal mode, i.e.
with °C, °F or K eng. units; if special is selected the instrument will use the eng. unit
specified later and will not perform any convers and no Rj compensation for Tc.
DESCRIPTION:
It is possible to enter four characters here to define the type of sensor.
By pressing the <Alt> key, and then typing 144 or 135 on the numerical keyboard Pt or
Tc character will appear on the CL520 series display.
mVL / mVH / V / mA / Ohm /
kOhm / Hz / pulse :
The sensor signal type to be linearized.
Eng. Unit
(only SPECIAL mode):
This procedure selects the technical unit that is going to be used in the values to be
linearized.
OFFSET (only for Rtd):
The offset value of the sensor must be typed in.
DP max FOR °C, °F & K:
The maximum number of decimal places (dp) has to be selected here.
CREATE NEGATIVE
SEGMENT:
With this option the values to be considered for the linearization are typed in. The first
value is the start of the segment expressed in the formerly defined technical unit, the
second is its relative value in degrees. The other values are the other known points of
the segment. To end data input, type "last". This option will consider all the negative
values.
CREATE POSITIVE
SEGMENT:
This option is the same as above, but the values have to be positive.
LIMITS in °C:
This option asks for the low and high temperature working limit.
An example can be useful to understand how the whole procedure works:
"Tc P" linearization with points:
-4 mV
-2 mV
0 mV
10 mV
20 mV

with one decimal point.
From the main page menu, select the "Create/Edit linearization data" option pressing the <1> key. Select the "Create by
normal data" option and insert the data as shown in the following figure:
When the last required datum is inserted, the program will present the page to input the negative data segment. When
the last segment data is inserted, write ‘last’ to finish.
When the last required datum is inserted, the program will present the page to input the positive data segment. When the
last segment data is inserted, write ‘last’ to finish.
At this point the program will show the sensor working limits page input:
13
When the last datum is inserted, the procedure will show the main menu.
It is possible to save the data using the “Save data to file” option and then to download it in the CL520 series using the
“Send data to CL520 series” option.
3.3
Load Data from File
This option allows to load in the PC memory disk-stored linearization files. The program will ask for the directory where
the file and the filename are located. It's not possible to load files with a suffix different than .LIN.
In order to have a list of the available files, use the “List .LIN and .RAW files” option.
3.4
Display Data
When a linearization has been loaded or edited, it's possible to study it using this option, that enables the user to look at
all the parameters needed for its linearization.
Use the <F1> key to show the next page.
14
3.5
Save Data on File
This option transfers the linearization data stored into the PC memory to the disk.
The file will be a .LIN type file, and it will possible to recall it with the option “Load data from file”.
3.6
Send Data to calibrator
Once the linearization parameters have been inserted and checked, it's time to linearize them and send them to the
calibrator.
When this option is selected, it will be asked what kind of linearization is needed. There are three possibilities:
LINEAR:
POLYNOMIAL:
SPLINE:
The linearization is obtained with a linear interpolation of the values.
The linearization is obtained with an interpolation derived from a polynom, definable in this option.
The linearization is obtained using the spline mathematical function on the defined values.
When the linearization is complete, the raw data (it means data that can be used directly by the CL520 series, after all
the calculations), are transferred to the MicroCal by the serial interface. The calibrator has to be connected, as described
in LOGMAN chapter, to the communication port of the PC.
A file is then saved on disk, with the .RAW suffix and the identification defined when creating the linearization.
3.7
Send Raw Data to calibrator
This option asks for a raw data filename. When this name is typed, LINMAN will load the file from disk, and then it will
transfer data on the CL520 series.
This option is particularly useful when lots of special sensors are used, and a library of them is present on disk.
15
3.8
Print Data
When this option is selected it will be necessary to have the printer correctly set, as all the linearization data will be sent
to the printer to get an hard copy of them.
3.9
List .LIN and .RAW Files
When selected, this option asks for a directory where to look for the files with a .LIN or .RAW suffix.
When the directory has been selected, that files will be listed as when the command DIR is used from the DOS
command line.
3.10
Remove Data from PC Memory or from calibrator
These two options are used to delete a previous linearization on the PC or on the calibrator.
When old one is deleted, a new one can be inserted.
IMPORTANT:
ALWAYS SAVE DATA BEFORE DELETING THEM FROM THE PC MEMORY !
OTHERWISE THEY WILL BE LOST.
3.11
Exit from the Program
When this option is selected, the program ends and the system returns to the previous application.
The same effect can be obtained by pressing the <F10> key.
NOTE: ALL DATA WILL BE LOST.

CALIBRATION PROCEDURE MANAGER (CL520-CPS)
Standard Agencies and Quality Auditors require the collection, organization and analysis of traceability documents.
CL520-CPS (CALPMAN) is able to transfer a selection of calibration routines from a PC to the internal memory of the
instrument in order to simplify field calibrations selecting the suitable tag number.
When a plant has a large number of process instruments, checks and field calibrations are really important in order to
keep the compliance with ISO 9000 requirements.
OMEGA with CALPMAN, coupled with the powerful CL520 series calibrator, grants the possibility to keep these
instruments under control.
The calibration data for the required instruments can be stored into the CL520 series memory following the instructions
detailed in this manual.
The data of each calibration procedure can be stored together with the name of the TAG, with engineering units, process
info, calibration points and a two allowed levels of error.
The calibrator can be used as a generator or as a recorder or both; its input and output terminals can be used to
generate, receive and compare inf.
After the calibration check, CL520 series will indicate if the checked instrument is within its specifications or if it has to be
verified; and a decision can be made by the plant technicians. The status of every instrument before and after its
calibration can be recorded and recalled later.
Benefits to be gained from this system are:
•
•
•
Optimisation of the Maintenance period. By keeping a record of the time required between necessary adjustments,
the optimum maintenance period can be determined.
Print of the Report of Calibration. A calibration report can be printed for each TAG.
Aid in maintenance planning. Data can be used to analyse the time and cost required for instrument calibrations and
can aid in planning manpower, specifying supplier, etc.
ATTENTION
THE CL520-CPS (CALPMAN) VER. 4.000 CAN RUNNING ONLY WITH CL520 SERIES FIRMWARE VERSION 4.000 ORTHE
FOLLOWING ONE. THE TAG SET-UP FILES OF CL520-CPS V. 4 ARE NOT COMPATIBLE WITH THE PREVIOUS VERSION.
THE CL520-CPS VER. 4 IS ABLE TO UPGRADE THE OLD TAG SETUP AND THE RESULTS FILES: MAKE A COPY OF THE OLDER ONES IF
YOU NEED TO USE THE OLD VERSION AGAIN.
Test and calibration data can be memory stored and downloaded to a PC to document the calibration activity that allows
to build a quality control chart/data bank from a single calibration sheet to a detailed historical report.
Each instrument, called “Tag”, to be calibrated/inspected is identified by 16 alphanumeric characters.
Three additional lines of 16 characters are available for a more detailed description of the instrument to be calibrated. A
typical example is shown below :
Tag
= Pressure Trx 128
Auxiliary information
= High temp trap
Area n.21T68
Stafford Station
The overall capabilities of the combination between CL520 series + CALPMAN software are the following :
−
CL520 series can store up to 50 Tags
−
Each Tag can be tested in different calibration steps (Test Point)
−
Each Tag can be identified with an alphanumeric code of 16 characters
−
Plant location/Plant section can be identified with three additional lines every 16 alphanumeric characters
−
The Operator/Inspector’s name can be written with up to 16 alphanumeric characters
−
The Test procedure can be prepared in a PC and downloaded into a CL520 series when required
−
The Test procedure can be eventually directly loaded on the field and downloaded into the PC
−
Direct test of analog / digital signal and pressure indicators
−
Direct test of Signal and Pressure Transmitters with comparison between input and electrical signal output
−
Direct test of Pressure Transmitters at actual programmed test points or with an automatic calculation of
actual errors with inlet pressure in an acceptable deviation band from the Test Point level.

This area contains the main information for the current Tag.
TAG (NAME) :
This is the name of the TAG. With this name the tag will be managed both from CL520 series and
the disk;
DESC(RIPTION) :
In this lines a description of the instrument under test can be typed in;
MODE :
This option allows to select the way the calibrator has to work:
CALIBRATOR OUT :
CALIBRATOR IN :
CALIBRATOR IN/OUT :
STEP TIME :
CL520 series generates a signal. This function is used to calibrate
and test signal indicators, recorders, etc.
CL520 series reads a signal. This function is used to calibrate and
test signal generators (eg. Tc, Rtd, etc.)
The calibrator generates a signal and reads another one
simultaneously. This function is used to calibrate and test signal Trx.
Sets the time between one step and the next one. Note that a null time indicates a manual selection of
the step in CL520 series;
Type area :
In this area it is possible to select the type of signal to be generated, measured or both of them according to the selected
"MODE" option. For every particular type of signal, other pieces of information have to be typed in.
In the following figure, for example, are shown the Tc output parameters : the Tc type, the temperature scale, the
engineering unit, decimal numbers, the compensation type.
20
In the following figure, for example, are shown the X input parameters : the electrical signal type, the scale type (linear or
square), the low and high values of the electrical signal, the lowX and highX value of the engineering scaled unit, the
engineering scaled unit and decimal numbers.
AVG, WEIGHT : This parameter permits to set the average weight to program the digital low pass filter. This parameter,
if it isn’t set on zero, allows measurements of an unstable input signal. See par. 8.10 in CL520 series
instruction manual.
Accuracy area :
In this area it is possible to set the error parameters of the instrument to be checked.
REVERSE ERR(OR) :
Activating this function, the resultant error has the sign changed.
The error can be checked in two ways:
SPAN:
The error is calculated on the instrument range : In this case, the low scale
and full scale values of the instrument to be checked have to be typed in.
READING :
The error is calculated on the instrument reading
In both cases, four values are to be inserted :
WARN(ING) :
If the error of the instrument should exceed the WARNING value, CALPMAN
considers the instrument calibrated. Anyway it is equally suggested to check
it. The values to be specified are BAND % and OFFSET:
WARNING = ± (BAND% WARN + OFFSET WARN)
If the error is comprised within the WARNING band, set in by the above
formula, CL520 series will mark the measure with a WARN message.
21
FAIL :
If the instrument error exceeds the FAIL value, CALPMAN will consider the
instrument out of calibration. The values to be inserted are BAND % and
OFFSET, using the same formula:
FAIL = ± (BAND% FAIL + OFFSET FAIL)
If the error is in the fail band, or higher than it, CL520 series will mark the
measure with a FAIL message.
Step area :
This option allows to set the steps value for programming the calibration procedure.
Example
The following example will be useful for a better understanding:
Tag name: "EE1234"
Descr. : It is a Tc indicator with accuracy ±(1% of rdg +1°C)

When a tag is running, you'll have to set it in different ways according to the calibration mode:
CALIBRATOR OUT:
type in the value read on the target instrument, and press <STO> to confirm the
value.
CALIBRATOR IN, InP or IN/OUT: wait for the read value to be stable, then press <STO>.
CALIBRATOR InP/IN:
wait for the read value to be stable and in the reference band, then press <STO> (the
<STO> key lits only if the measured value is in the reference band).
You'll see that the reported value will be comprised between two parentheses:
If the parentheses appear inverted on the display (green into a black square), it means that the value is in the WARN
band. If, instead, the whole value is inverted, it is a FAIL value.
23
A normal displayed value is accepted as correct (OK value).
Once the process is ended, CL520 series will go back to the tag description page, and the BEFORE mark will report the
results: WARN, FAIL or OK.
It's now that a decision has to be made:
•
•
if the result is OK, the procedure can be ended, if the result is warn a check is suggested,
if it is a Fail message, the instrument has to be recalibrate.
It is possible to repeat or to jump a calibration step pressing the <Shift>+<5> and <Shift>+<0> keys.
When the checking operations on the instrument has been completed, it's possible to start with the AFTER (calibration)
procedure.
Note: The calibration data will not be saved if some calibration step was jumped. Anyway a warning message will
appear on the display.
To begin the AFTER calibration procedure press the <ENTER> key and the <5> key then press the <RUN> key to begin
the calibration procedure.
The AFTER procedure works in the same way as the BEFORE one.
