The transmitter can be used with any GLI Model 3400-
series contacting 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, resistivity or TDS
•
Measured temperature (
°
C or
°
F)
•
Measured conductivity, resistivity or TDS, and temperature
•
Measured analog output value (mA).
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.
It is highly recommended to calibrate the transmitter using
GLI’s simple DRY-CAL method, which eliminates the need
to prepare a reference solution. However, the transmitter
can be traditionally “wet” calibrated. For calibration details,
refer to PART THREE, Sections 4.2 and 4.3 or 4.4. The analog
output loop can also be calibrated (Section 4.4).
The transmitter’s isolated 4-20 mA analog output can be
assigned to represent one of these measurements:
•
Measured conductivity, resistivity 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 output setup details, see PART
THREE, Section 3.4.
NOTE:
During calibration, the analog output is automati-
cally held at the last measured value and, upon
completion, returned to its active state.
