The analyzer can be used with any GLI 5-wire Differential
Technique pH or ORP sensor, or any conventional combi-
nation electrode. The analyzer will accept an NTC 300 ohm
thermistor, Pt 1000 RTD or Pt 100 RTD temperature com-
pensator element. Typically, one of these elements is built
into the pH or ORP sensor.
The MEASURE screen (normal display mode) can provide
different readouts of measured data. With the MEASURE
screen displayed, press
Õ
Õ
and
Ö
Ö
key
to show:
•
Measured pH (or ORP, if selected).
•
Measured temperature (
°
C or
°
F).
•
Analog Output 1 and 2 values (mA).
•
Measured pH (or ORP) and temperature.
For security, you can enable a passcode feature to restrict
access to configuration and calibration settings to author-
ized personnel only. See PART THREE, Section 3.6 for
details.
Four methods are available to calibrate the analyzer for pH.
See PART THREE, Section 4.2 for details. For ORP cali-
bration, refer to Section 4.3. Each analog output mA value
can also be calibrated (Section 4.4).
The analyzer provides two isolated analog outputs (1 and
2). Each output can be set to be 0-20 mA or 4-20 mA, and
assigned to represent one of these measurements:
•
Measured pH (or ORP).
•
Measured
temperature.
Parameter values can be entered to define the endpoints at
which the minimum and maximum analog output values are
desired (range expand). For analog output setup details,
refer to PART THREE, Section 3.4.
