I. Introduction
A. Instrument Function Overview
The MS3500L data logger is designed to provide a continuous record of corrosive activity in remote
locations that are infrequently visited, such as cross-country pipelines, and unmanned production
platforms. However, this unit finds equal application in locations that are inconvenient or difficult to
access on a regular basis, such as refinery overheads, and flue-gas stacks.
The MS3500L is completely self-contained with the onboard battery system supplying the total power
requirement for operation. It can be used with any of Metal Samples’ LPR probes, or those of all other
major manufacturers. Once in place, it will automatically read the probe at customer-selected intervals
and store the resulting data in the unit’s onboard memory. The onboard memory will collect up to
3,000 data points before data download is required. With practical data collection intervals (1 - 2
hours), the unit may be unattended for several months between downloading operations.
An optical, infrared, RS232 communication link is provided for data download to either an IBM
compatible PC or Metal Samples’ MS1500L portable LPR data logger. Downloaded data may be
analyzed, reviewed, or reported by conventional spreadsheet, database, or mathematical software
packages.
The infrared communication link is an integral part of the intrinsically safe design of the MS3500L.
Optical instead of electrical, this unique feature permits data to be downloaded to an MS1500L while
still in the hazardous area.
Another unique feature of the MS3500L is the high level of onboard intelligence. The two-line, 20character lcd allows visual review of all historical data in memory and reads directly as “total metal loss”
and/or “average corrosion rate”. This is in contrast to other commercially available units that store and
display only the raw “resistance ratio” that requires additional manipulation to provide useful and
intelligible data.
The lcd screen, together with the 2-key membrane keypad, provides a user-friendly, interactive,
prompting system that is used for both system setup and data review. This makes the MS3500L the
most advanced unit of its type on the market.
By adding a 4-20mA communication facility, the MS3500L becomes an MS3510L. This allows
continuous transmission of data, via a 4-20mA loop, to a plant computer or central data logger, for
integration with other real-time process parameters. This data transmission can be accomplished
without disruption of the unit’s basic logging and data storage operations. The 4-20mA loop extends
the capabilities of the unit to include conventional, in-plant, real-time data communication.
The MS3500L unit uses a NEMA 4 (IP-65) enclosure, making it suitable for use in the most extreme of
outdoor conditions.

II. Installation
A. Enclosure & Mounting Details
The MS3500L enclosure is fabricated in carbon steel with a baked-on, high-build epoxy coating. The
unit has a hinged door that is secured, when shut, by screw-down clamps that discourage unauthorized
tampering. The enclosure is constructed to NEMA 4 (IP-65) weatherproof standards, making it
suitable for the most rigorous of outdoor environments.
The overall dimensions of the unit are 11½" (height), 9" (width), 4d" (depth), making it a convenient
size to mount even in the most confined of locations. For the best results, the instrument should be
mounted within ten feet of the probe location. To facilitate this, the unit has a versatile mounting flange
with four .31" diameter, mounting holes. Overall dimensions and mounting hole centers are shown in
Figure 1.
Figure 1. MS3500L Dimensions

B. Battery Installation
The MS3500L instrument uses six 1.5V, AA size batteries, connected in series, as a primary power
source. While any AA size battery can be used, Duracell or Procell Type MN1500 or PC1500
batteries are required to meet the intrinsic safety certification requirements. Since the MS3500L
operates in a low power consumption mode between readings, battery life will be a function of the
reading interval and measurement time cycle set by the user. At the most frequent reading interval (1
per hour), a minimum battery life of four months is to be expected. More practical intervals, such as
every 12 or 24 hours, will yield a battery life in excess of twelve months. Generally, to avoid
unexpected power drains, batteries should be replaced once every six months. In the instance of a low
reading interval (1 per 4 hours or less), three month battery replacement is advisable.
Batteries are mounted in the back of the MS3500L/MS3510L, behind the instrument screen and
keyboard panel. The batteries are accessed by loosening the two thumbscrews on the right side of the
panel, then swinging the hinged panel open to the left. Care should be used when opening and closing
the panel to ensure that the internal wiring is not pinched or damaged. Once the panel is opened,
batteries can be inserted or removed from the spring-loaded retainer as shown below.
Note: Battery replacement should only be performed after removing the MS3500L from
hazardous locations.

C. 4-20mA Loop Installation
The MS3510L is available with a 4-20mA communication outlet that allows continuous, real-time
integration of LPR corrosion data with other process parameters in the main plant computer. The 420mA outlet port is a 2-pin military connector (MIL 14S-9SF) on the base of the unit, marked 420mA. The mating connector for this outlet (ET0612) is supplied as part of the accessories for the
MS3510L unit. The positive lead of the communication loop should be connected to the “A” terminal
of the ET0612 mating connector, and the negative lead to the “B”. The loop can then be connected to
the 4-20mA instrument outlet.

The loop should be powered by 10-24 VDC. For hazardous applications, an appropriate Zener
barrier should be installed in the loop, or power should be supplied from an intrinsically safe repeater
power supply. Typical hazardous installation is shown on page 38.

D. Probe-Instrument Connection
The MS3500L can be mounted directly onto an LPR probe. However, in many instances it is either
inconvenient or undesirable to mount the instrument directly onto the probe. For these circumstances a
IN3500-4, ten-foot, extension cable is provided. The extension cable has integral connectors with a
guiding keyway to ensure correct pin alignment when attached. The female connector mates with the
probe, or probe adaptor, and the male connector mates with the central terminal on the base of the
MS3500L unit.
The length of the extension cable has been carefully determined so as to avoid excessive
signal noise. Longer extension cables should only be employed after consultation with Metal
Samples.
The extension cable provided will mate directly with any Metal Samples’ LPR probe or those of any
other major manufacturer, which use a standard six-pin connector. For probes which use a five-pin
connector instead of a six-pin connector, the IN1500L-5 (6 to 5 pin adaptor) is used.
Figure 4. Adapter Connection for 2-Electrode LPR Probe
The user may from time to time, encounter probes with a non-standard probe connection, especially if
the probes are of non-standard commercial variety. To account for this possibility an IN1500L-4, flying
lead, cable adaptor is available. This comprises a conventional instrument end connector, attached to a
cable with flying leads, terminated in alligator clips. This allows for individual terminations to be made to
any non-conventional probe, providing the probe connector pin-out is known. If the user is unfamiliar
with the pin-out on any particular probe, this can be established prior to probe installation by performing
a simple continuity check between the probe electrodes and the probe connector pins.

E. Data Download Connection
To download data from the MS3500L to a PC use the Optilink Cable and Serial Port Adaptor.
Note: Do NOT plug the phone jack on the end of the Optilink Cable directly into your PC's
modem.
If a serial port is unavailable on your PC and you wish to connect the MS3500L to your PC via a USB
port, you may use a serial to USB converter. This converter is not included with the instrument, but may
be purchased serparately at major electronics retailers.
To download data from the MS3500L to a MS1500L connect the Optilink Cable directly to the
MS1500L.
Detailed instructions of data downloading are given on p.16.

III. Setup and Operation
A. Main Menu Overview
Once the batteries are installed in the MS3500L/3510L, the instrument screen may be activated by
pressing either of the keys on the front panel. The company name “METAL SAMPLES” and software
version will appear, then after a few seconds will automatically change to the first of the function screens
that constitutes the main menu.
A series of nine function screens can be accessed simply by scrolling using KEY 1 on the instrument
keypad. Each of the nine function screens allows entry into a submenu to initiate an action such as
MEASURE PROBE or START DATA LOGGING; alternatively it allows input of data such as probe
identification or reading interval.
Each of the function screens and their submenus are fully explained later in the manual. The following
diagram shows the sequence of access to the twelve function screens:
8
As explained, each function screen gives access to a submenu, the purpose of which is briefly described
below:
MEASURE PROBE. This will override the normal interval of logging readings to allow
a spot check reading to be obtained on screen.
MEASURE METER PROVER. Used to test the instrument with the Meter Prover.
VIEW STORED DATA. Allows visual review of all readings logged.
START DATA LOGGING. Initiates the data logging process after input of appropriate
start-up data.
ENTER PROBE ID Allows input of probe type and reading interval. Together with "SET
TIME AND DATE". This constitutes initial start-up data.
SET READING INTERVAL. This allows the initial reading interval that is input under
"PROBE ID" to be changed without deleting stored data.
SET MEASUREMENT TIME. This allows the initial measurement (polarization) time that is
input under "PROBE ID" to be changed without deleting stored data.
SET TIME AND DATE. This constitutes the initial step of start-up data, allowing correct
setting of the “real time” clock.
UPLOAD TO MS1500L. This activates the download of stored data to the MS1500L or to
a personal computer.
UPLOAD TO PC. This activates the download of stored data to a personal computer.
SYSTEM SHUTDOWN. This will stop the logging process, and minimize power
consumption without deleting stored data.
TEST MODE. This allows a calibration check of the 4-20mA loop, and supplies instrument
trouble shooting data.

B. Program Setup
Having installed the batteries, the MS3500L is ready for start-up programming which compromises the
following sequence:
• SET TIME AND DATE
• ENTER PROBE ID
• START LOGGING
1.Set Time and Date
This operation is illustrated below:
The screen of the instrument is initially activated by pressing either key. The “SET TIME & DATE”
function screen is then accessed by scrolling through the main menu using KEY 1. KEY 2 allows entry
into the submenu, and the time and date setup screen will be shown. Each digit of the time, day, month,
and year is sequentially set using KEY 1 to select the appropriate digit, and KEY 2 to enter the digit and
move the next digit of the time and date sequence.
Once the final digit of the year is entered, using KEY 2, the screen will automatically change to the time/
date display screen. This screen shows the time and date as set up. KEY 2 will accept and store this
time and date. KEY 1 will reject this information. Either key will automatically return the user to the
“MEASURE PROBE” screen of the main menu. If the time and date has been rejected, scroll to the
“SET TIME & DATE” function screen, re-enter the submenu and make the necessary corrections. If
the time and date are correct, and the user has used KEY 2 to accept the information, scroll to the
“ENTER PROBE ID” function screen to continue with program setup.
Please note that the time and date, once set, should not require alteration except after battery
replacement. Should the user decide to change the time and date while probe data is stored in
memory, all data will be displaced in time and highly inconvenient to interpret.
10
2. Enter Probe ID
This function will allow the user to identify the particular probe type or installation location with a unique,
4-digit tag number. Additionally, it allows the selection of the desired measurement type. Finally, it allows
the user to select the data collection rate. The operational sequence is as follows:
Once the “ENTER PROBE ID” function screen is located on the main menu, KEY 2 will give access to
the submenu. The initial screen of the submenu allows deletion of any stored data. Normally there will
be no data stored, since any useful data set will have been previously downloaded. If no useful data is
stored in the unit, press KEY 1 which will delete all existing data and give access to the Probe ID
screen. If useful data is stored, use KEY 2 to return to the main menu and download existing
data (p. 19) prior to proceeding.
The Probe ID screen allows you to insert a 4-digit identification number for the probe and/or
monitoring location. Each digit is selected with KEY 1, and individually entered with KEY 2. When the
fourth digit of the ID number is entered, the screen will automatically change to the “measurement type”
selection screen.
The measurement ID screen allows the user to select the measurement type by using the “ARROW”
keys to scroll, and the “ENTER” key to select. The measurement types that are selectable are:
LPR3A:
3-electrode, linear polarization (corrosion rate)
using anodic polarizing current
LPR3C:
3-electrode, linear polarization (corrosion rate)
Using cathodic polarizing current
LPR2:
2-electrode, linear polarization (corrosion rate)
GALV:
2-electrode, zero-resistance, current measurement
POT.:
2-electrode potential measurement
11
Upon entry of the probe element ID, the screen will automatically change to the cycle time screen. This
allows the user to select the cycle time with which the probe will read. This can be set in increments
from one minute to 15 minutes. KEY 1 is used to increase cycle times, KEY 2 is used to enter the
selected cycle time. The reading frequency is next set on the screen as hours (two digits) and minutes
(two digits). The default reading is 1 per hour. Each digit is selected by a KEY 1 scroll, and individually
entered with KEY 2. Once the last minute digit is entered, the next screen will be displayed which
shows the reading frequency as entered, which can then be accepted (KEY 2) or rejected (KEY 1). If
accepted, the screen will revert to the “MEASURE PROBE” function screen, and the user can proceed
to the “START DATA LOGGING” function. If rejected, the screen will also revert to the “MEASURE
PROBE” function screen, but the user is now required to access the “PROBE ID” function and reset/
correct the probe ID, the element ID, and the reading frequency prior to commencing with the data
logging process.
3. Start Data Logging
This is the simple sequence of commands that sets the logging process in motion:
The submenu is entered from the “START DATA LOGGING” main menu function screen, using KEY
2. The first submenu screen is the “SYSTEM READY” screen, from which KEY 2 will start the logging
process and shut down the screen for power conservation. If, for any reason, the user does not wish to
commence logging, KEY 1 will allow escape to the “MEASURE PROBE” screen of the main menu.
Once logging is activated, it will continue until the user activates the system shutdown routine, or the
batteries discharge. In either event, all data collected to this point will be retained, but no additional data
will be collected. Entering a new probe ID will also stop the logging process and eliminate all existing
probe data from the memory. Prior to entering new probe ID, ensure that all useful data is
downloaded.
Should logging continue in an uninterrupted fashion until the memory capacity of the unit is full, additional data will sequentially overwrite the initial data points stored in memory.
The user should always set a download schedule of sufficient frequency so that no more than
3,100 readings are taken between download operations.
12
C. Measure Probe Function
The “MEASURE PROBE” function allows the user to make a spot-check probe reading at any time,
without constraint of the normal logging interval. The submenu sequence is illustrated below:
The first screen of the “MEASURE PROBE” submenu displays the probe I.D. number and
measurement type. KEY 1 exits to the main menu “MEASURE PROBE” function screen and KEY 2
will activate a measurement.
If KEY 2 is used to activate a measurement, the second submenu screen will be shown that displays the
probe I.D. and test mode, and a “PLEASE WAIT” notation. After approximately 5 minutes, the reading
will be complete and the third submenu screen will be automatically displayed. This screen will show
the current corrosion rate in MPY, and will give a KEY 1 EXIT option, and a KEY 2 ENTER (save)
option. KEY 1 will return the user to the “MEASURE PROBE” function screen, KEY 2 will save the
probe reading and automatically display the fourth submenu screen.
13
D. View Stored Data Functions
This facility allows all data stored in the MS3500L to be called up on the screen for review. The
submenu sequence is shown below:
After pressing either key to access the MS3500L screen, KEY 1 is used to scroll to the “VIEW
STORED DATA” function screen. KEY 2 is then used to enter the submenu.
Previous readings may be accessed sequentially using KEY 2. KEY 1 will exit the review screen, and
display metal loss (MILS) and average corrosion rate (MPY) for the reading dis-played when the exit
key is used. The metal loss/corrosion rate screen will display for approx-imately 30 seconds before
automatically returning to the “MEASURE PROBE” function screen.
The “VIEW STORED DATA” function may be used at anytime without disrupting normal logging.
14
E. Set Reading Interval Function
This function permits the reading interval to be changed at any time during logging without disrupting the
logging process or deleting the stored data. The operation sequence is as follows:
After any key is used to activate the screen, KEY 1 is used to scroll to the “SET READING INTERVAL” main function screen. KEY 2 then allows entry into the submenu.
The current reading interval is displayed as hours and minutes. Individual digits may be altered using
KEY 1, and entered using KEY 2. After the final hour digit is entered, the screen will automatically
change to a reading interval confirmation screen. The interval as entered is displayed. KEY 1 will exit
to the “MEASURE PROBE” main function screen without entering (saving) the new interval. KEY 2
will enter (save) the new reading interval, then automatically return to the “MEASURE PROBE” main
function screen, further logging takes place at the new reading interval.
15
F. Downloading Data
Data stored in the MS3500L/3510L unit may be downloaded, via the Opti-Link port, directly to a PC.
Alternatively, data may be downloaded to Metal Samples’ MS1500L Hand-Held Data Logger, and
subsequently transferred to a PC. Direct downloading is usually preferred in a control room or
laboratory environment. Where several MS3500L/3510L units are distributed in a field environment, the
data is most conveniently transferred via the MS1500L to a PC. The MS1500L will accept data from
as many as one hundred MS3500L/3510L units for subsequent transfer to a PC.

2. Upload to MS1500L
The user must first connect the IN3500-2 cable between the Optilink™ connector on the MS3500L
and the phone jack connection on the MS1500L.
Once the communication connection is made between the MS3500L and the MS1500L instruments,
switch on the MS1500L and select a probe ID that corresponds to the probe ID of the MS3500L in
question. The user must now scroll to the communication menu on the MS1500L and press enter.
The MS1500L communications submenu has the following screen sequence for MS3500L download
operations:
*Before executing this command, set MS3500L to “Waiting for Link Up” mode.
After selecting the MS3500L “DOWNLOAD” option on the MS1500L communications menu, the
communications mode should be selected on the MS3500L instrument. This is achieved by scrolling
through the main functions menu, using KEY 1, until the “UPLOAD TO MS1500L” screen is reached.
The submenu is accessed using KEY 2. The MS3500L screen will now display “WAITING FOR
LINK UP”, and a KEY 1 exit option. The MS3500L is now waiting for the download instruction from
the MS1500L. This instruction is given by pressing enter on the MS1500L unit. The MS1500L screen
will now display the probe ID and type for the MS3500L in question, plus an option to use “EXIT” to
abort the transfer. Data transfer is now in progress.
Upon completion of data transfer, the MS3500L screen will display “TRANSFER COMPLETE” and
the MS1500L screen will automatically exchange the “EXIT TO ABORT” option for “ENTER TO
CONTINUE” option. At this point the MS1500L can be disconnected, and the user may download
data from the next MS3500L or upload data from the MS1500L to the PC.
25
G. System Shutdown Function
This function allows the user to suspend the logging process for any period of time without data
loss. The menu screen sequence to operate the function is as shown below:
To activate the system shutdown function, the user should scroll through the main function screens using
KEY 1 until the “SYSTEM SHUTDOWN” function screen is reached. The user can now use KEY 2
to access the submenu. The screen will now ask for confirmation. KEY 2 will activate system
shutdown; KEY 1 will return the user to the main function screens. If KEY 2 is used to activate
“SYSTEM SHUTDOWN”, data logging will cease but all existing data will be retained in memory.
When the user wishes to reactivate the logging process, either key can be used to access the screen,
and KEY 1 will then resume the logging process.
H. Test Mode Function
The test mode function is used for factory trouble shooting of faulty instruments returned for repair and
in initial quality assessment of newly manufactured instruments. This function is not required for
normal instrument operation.

Appendix B - Derivation of Alloy Constant
The variation of the Stern Geary equation, relating the corrosion current icor, to the polarization resistance
E/ I is given by:

To convert the polarizing current to the conventional MPY (“MILS PER YEAR”) units of corrosion,
Faraday’s laws are applied as follows:

Faraday’s constant (coulombs)
working electrode surface area in cm2
equivalent weight of corroding metal (gms)
density of corroding metal (gms. cm-3)
corrosion rate (mpy)
28
Consequently, when the instrument calculates the corrosion rate (mpy) from the measured polarizing
current ( I), a means needs to be found whereby the instrument can “know” the appropriate value of
E/d, and perform the correct calculation of corrosion rate. This is achieved in the conventional, threeelectrode LPR measurement by varying the surface area of working electrode in proportion to the E/d
value of the metal/alloy in question, thus avoiding the need to program special correction factors into the
instrument for each and every alloy.
Unfortunately, the major producer of the two-electrode probe uses a constant surface area for the
working electrode, irrespective of the metal/alloy under examination. Thus a correction factor has to be
applied for each metal/alloy under consideration. This is, in fact, the alloy constant used for twoelectrode corrosion rate measurements in the MS1500L unit. The basic formula for derivation of the
correction factor is:
Ak
Ak
E
d
=
0.55 x E
d
............................ 6
= alloy constant
= equivalent weight of metal/alloy in question (gms)
= density of alloy in question (gms. cm-3)
For pure metals, if the appropriate alloy constant does not appear in the MS1500L memory already, the
user can apply equation 6 to calculate, and program, the appropriate alloy constant into the instrument
memory.
Difficulties arise when trying to work out the equivalent weight of alloys. This is approached by use of a
weighted average, assuming all major metallic constituents corrode in proportion to their weight percent
for the alloy in question. In general, metallic constituents present in amounts smaller than 1% are
disregarded for the purposes of this calculation. An example of this is given below for AISI 302
Stainless Steel.
