Code 10
*T.SENS
Selection of the temperature compensation sensor. The default selection is the
PT1000 sensor, which gives excellent precision with the two wire connections
used. The other options give the flexibility to use a very wide range of other
conductivity/resistivity sensors.
The temperature sensors for the applicable conductivity sensors are as follows.
According to the conductivity sensor used, select the appropriate temperature
sensor.
* SC210G ......
PB36NTC
* SC211G ......
Pt1000
* SC8SG ........
Pt1000
* SC4A, SC4AJ
Pt1000
Code 11
*T.UNIT
Celcius or Farenheit temperature scales can be selected to suit user preference.
Code 12
*T.ADJ
With the process temperature sensor at a stable known temperature, the tem-
perature reading is adjusted in the main display to correspond. The calibration
is a zero adjustment to allow for the cable resistance, which will obviously vary
with length.
The normal method is to immerse the sensor in a vessel with water in it,
measure the temperature with an accurate thermometer, and adjust the reading
for agreement.
