IMPORTANT SAFETY INFORMATION
This analyzer is compliant with safety standards as outlined in:
FMRC Class Numbers 3600, 3611, and 3810 (U.S.A.)
CSA C22.2 No. 142 and C22.2 No. 213 (Canada)
EN 61010-1 (European Community)
Please read and observe the following:
•Opening the analyzer door exposes you to line power voltage, if present, at terminals on TB2 and TB3
inside the enclosure. This may be hazardous. Always remove line power before entering this area in
the analyzer. However, the analyzer door assembly contains only low voltage and is completely safe
to handle.
•Wiring or repairs should only be performed by qualified personnel and only to an unpowered analyzer.
•Whenever it appears that analyzer safety is questionable, disable the analyzer to ensure against any
unintended operation. For example, an unsafe condition is likely when:
1) The analyzer appears visibly damaged.
2) The analyzer fails to operate properly or provide the intended measurements.
3) The analyzer has been stored for long periods at temperatures above 158°F (70°C).
•This analyzer must be installed by specially trained personnel in accordance with relevant local codes
and instructions contained in this operating instruction manual. Observe the analyzer’s technical
specifications and input ratings. If one line of the line power mains is not neutral, use a double-pole
mains switch to disconnect the analyzer.

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 resistivity, TDS or a calculated Sensor A and B measurement, or to use specific
features of the instrument, refer to the appropriate sections in this manual for instructions.
A. CONNECTING SENSOR(S)/CONFIGURING TEMPERATURE ELEMENT(S)
1. After properly mounting the analyzer (PART TWO, Section 2), connect the GLI enhanced per-
formance contacting conductivity sensor(s), matching wire colors to terminals as indicated:

2. The analyzer is factory-set for use with the Pt 1000 ohm temperature element built into GLI en-
hanced performance contacting conductivity sensors. When using a sensor brand with a different
temperature element, or for fixed MANUAL temperature compensation, you must change the
temperature element type (see PART THREE, Section 4.2, subheading “Select TEMP
ELEMENT Type”).
B. CONNECTING LINE POWER
Important: Follow the instructions in PART TWO, Section 3.5 to connect line power to the analyzer.
C. ADJUSTING DISPLAY CONTRAST
Ambient lighting conditions may make it necessary to adjust display contrast to improve visibility.
With the MEASURE screen displayed, press and hold the ENTER key and simultaneously press the
×
×
or
Ø
Ø
key until attaining the desired contrast.
D. CALIBRATING THE ANALYZER
The analyzer must be calibrated so that measured values will correspond to actual process values. It
can be traditionally “wet”calibrated. However, since measured conductivity is greatly affected by
small changes in temperature, GLI strongly recommends using its DRY-CAL method for highest
measuring accuracy of conductivity and temperature. Besides, DRY-CAL is actually a normal part of

CONDENSED OPERATING INSTRUCTIONS
D. CALIBRATING THE ANALYZER -- (continued)
configuring the sensor characteristics during initial startup, and DRY-CAL eliminates the need for
conductivity reference solutions. This method also automatically sets the analyzer measuring
range to match the inherent range of the sensor’s cell constant. For more details about the benefits
of DRY-CAL, refer to the “Calibration Tip!”in PART THREE, Section 5.1.
NOTE: DRY-CAL eliminates the need for periodic re-calibration! The only requirement, depending
on the application, may be to periodically clean the sensor. Only when the sensor is re-
placed is it necessary to perform a new DRY-CAL calibration.
Calibration Tip! Each contacting conductivity sensor has a unique zero point and offset. Conse-
quently, when calibrating a sensor for the first time, always zero it according to step 1. Zeroing
provides the best possible measuring accuracy, and eliminates any discrepancy between Sensor A
and B measurement channels.
DRY-CAL calibration, routinely attained while configuring the analyzer for sensor characteristics, re-
quires entry of the sensor’s GLI-certified “CELL K”value and temperature “T FACTOR”which are
unique to each sensor. When using two sensors, enter each unique set of values using respective
sensor menu screens.
1. Zero the sensor if it is being calibrated for the first time. If not, disregard this step and perform
steps 2 through 14.
Zeroing Tip! If at any time during zeroing, the “ZERO: CONFIRM FAILURE?”screen appears,
press ENTER key to confirm. Then, use the
×

or
Ø
Ø
key to select between “CAL: EXIT”or
“CAL: REPEAT”and do one of the following:
•With the “ZERO? (CAL: EXIT)”screen selected, press ENTER key. After the “ZERO:
CONFIRM ACTIVE?”screen appears, press ENTER key to return the analog outputs and
relays to their active states (MEASURE screen appears).
•With the “ZERO?: (CAL: REPEAT)”screen selected, press ENTER key to repeat zeroing.
A. Make sure that the sensor is dry before zeroing.

To change the display format of the MEASURE screen (for example, from 0-2000 µS/cm to 0.000-2.000
mS/cm), refer to PART THREE, Section 4.2, subheading “Select DISPLAY FORMAT.”
NOTE: If the values you intend to measure are above the analyzer’s set measuring range (not its
selected display format), use a different sensor that has the appropriate nominal cell con-
stant. For a listing of sensor cell constants and their inherent measuring ranges, see Table A
in PART THREE, Section 4.2, subheading “Select DISPLAY FORMAT.”
E. COMPLETING ANALYZER CONFIGURATION
To further configure the analyzer to your application requirements, use the appropriate CONFIGURE
screens to make selections and “key in”values. Refer to PART THREE, Section 4 for complete con-
figuration details.
