GLI tests each sensor to provide a unique, certified tem-
perature T FACTOR because:
•
Temperature greatly affects conductivity measurement
accuracy.
•
The inherent ohm value of the Pt 1000 RTD temperature
element varies slightly from sensor to sensor, affecting
temperature measurement accuracy.
By entering the sensor’s unique T FACTOR, you enable the
transmitter to provide the highest possible measuring accu-
racy for both temperature and conductivity.

SPECIAL CASE -- ALTERED SENSOR CABLE LENGTH
(only for sensors with Pt 1000 temperature element*)
Changing the standard 20 ft. (6 m) sensor cable length, by
shortening it or adding an interconnect cable, affects tempera-
ture measuring accuracy. The GLI-certified T FACTOR is based
on standard cable length. To compensate for altered cable
length measuring error, change the certified T FACTOR entry:
