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

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
