CONDENSED OPERATING INSTRUCTIONS
This manual contains details for all operating aspects of the instrument. The following condensed in-
structions are provided to assist you in getting the instrument started up and operating as quickly as
possible. These condensed instructions only pertain to basic conductivity measurement opera-
tion. To measure % concentration or TDS, or to use specific features of the instrument, refer to the
appropriate sections in this manual for instructions.
A. CONNECTING SENSOR/CONFIGURING TEMPERATURE ELEMENT TYPE
1. After properly mounting the transmitter (PART TWO, Section 2), connect the GLI electrodeless
conductivity sensor, matching wire colors to terminals as indicated:
Sensor Wire Colors Connect To TB2
White Terminal 1
Blue Terminal 2
#LEARTerminal 3

Terminal UNUSED
'REEN4ERMINAL
2. The transmitter is factory-set for automatic temperature compensation using the Pt 1000 ohm tem-
perature element built into GLI electrodeless conductivity sensors. If you want fixed MANUAL
temperature compensation, change the temperature element type to “MANUAL” and enter a tem-
perature. For details, see PART THREE, Section 3.2, subheading “Select TEMP ELEMENT Type.”
B. CONNECTING DC POWER
Refer to PART TWO, Section 3.2, 3.3, 3.4, or 3.5 to connect DC power to the transmitter.
C. CALIBRATING THE TRANSMITTER
The transmitter must be calibrated so that measured values will correspond to actual process values.
Preferably, use the “COND CAL” calibration method to enter the known value of a properly prepared
conductivity reference solution. (To calibrate with a sample of the process, use the “SAMPLE CAL”
method to enter its known value determined by laboratory analysis or a comparison reading.)
Calibration Tip! Each electrodeless conductivity sensor has a unique zero point and span. Conse-
quently, when calibrating a sensor for the first time, always zero it according to step 1. Zeroing
provides the best possible measuring accuracy.
NOTE: An in-progress calibration can always be aborted by pressing the ESC key. After the
“ABORT: YES?” screen appears, do one of the following:
•
Press ENTER key to abort. After the “CONFIRM ACTIVE?” screen appears, press ENTER
key again to return the analog output to its active state (MEASURE screen appears).
•
Use

zeroing, the analog output is automatically “held” at the last measured value.)
H. After the “ZERO: CONFIRM CAL OK” screen appears, press ENTER key to end zeroing.
I. After the “ZERO: CONFIRM ACTIVE?” screen appears, press ENTER key to return the
analog output to its active state (MEASURE screen appears).
2. Prepare a reference solution that has a conductivity value within the measuring range that you
set for the transmitter. For best accuracy, the value of the solution should be near the typical
measured process value. For details on preparing a solution, refer to step 1 and TABLE E in
PART THREE, Section 4.3, subsection “COND CAL Method.”
3. Thoroughly rinse the clean sensor in de-ionized water. Then immerse the sensor in the prepared
reference solution. Important: Allow the sensor and solution temperatures to equalize. De-
pending on their temperature differences, this may take up to 30 minutes.
NOTE: Suspend the sensor to prevent it from touching the container. Simply laying it into the
container will produce calibration error.
Calibration Tip! If the “COND CAL: CONFIRM FAILURE?” screen appears at any time during
calibration, press ENTER key to confirm. Then, use the

confirm. This active screen appears showing the measured reference solu-
tion value.
10. Wait for the reading to stabilize which may take up to 30 minutes. Then press ENTER key. The
“PLEASE WAIT” screen may appear if the reading is still too unstable. After the reading has sta-
bilized, this static screen appears showing the “last-measured” value.
11. Use arrow keys to adjust the “last-measured” value to exactly match the known value of the ref-
erence solution, and press ENTER key to it and complete calibration (“CONFIRM CAL OK?”
screen appears).
12. Re-install the sensor into the process.
13. Press ENTER key to display the active measurement reading on the “CONFIRM ACTIVE?” out-
put status screen. When the reading corresponds to the actual typical process value, press
ENTER key again to return the analog output to its active state (MEASURE screen appears).

Analog Output
The transmitter can be used with any GLI Model 3700E-series
electrodeless conductivity sensor. These sensors have a
built-in Pt 1000 RTD temperature compensator element.
The MEASURE screen (normal display mode) can provide
different readouts of measured data. With the MEASURE
screen displayed, press
Õ
Õ
or
Ö
Ö
key to show:
•Measured conductivity, % concentration or TDS
•Measured temperature (°C or °F)
•Measured conductivity, % concentration or TDS and temperature
•Measured analog output value (mA)
•Uncompensated conductivity corresponding to concentration read-
out (only shown when transmitter is set to measure concentration)
For security, you can enable a passcode feature to restrict ac-
cess to configuration and calibration settings to authorized
personnel only. See PART THREE, Section 3.5 for details.
Because each sensor has a unique zero point and span,
always ZERO the sensor in air when calibrating it for the
first time (PART THREE, Section 4.2). Depending on the
configured measurement (conductivity, % concentration or
TDS), different methods are available for calibrating sensor
span (see Section 4.3, 4.4 or 4.5 respectively). The analog
output loop can also be calibrated (Section 4.6).
The transmitter’s isolated 4-20 mA analog output can be
assigned to represent one of these:
•Measured conductivity, % concentration or TDS
•Measured temperature.
Parameter values can be entered to define the endpoints at
which the 4 mA and 20 mA analog output values are de-
sired (range expand). For analog output setup details, see
PART THREE, Section 3.4.
