5-3-2. Temperature measuring functions

Code 10 *T.SENS

Selection of the temperature compensation sensor. The default selection is

the Pt1000 Ohm 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.

Code 11 *T.UNIT

Celsius or Fahrenheit temperature scales can be selected to suit user

preference.

Code 12 *T.ADJ

With the process temperature sensor at a stable known temperature, the

temperature 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.
