Adjusting the temp probe
This function allows you to compen-
sated for the individual temperature
probe tolerance and the influence of
the lead resistances to increase accu-
racy of temperature measurement.
Adjustment may only be carried out
after the process temperature has been
precisely measured using a calibrated
reference thermometer!
The measurement error of the refer-
ence thermometer should be less than
0.1 °C. Adjustment without precise
measurement might result in consider-
able deviations of the measured value
display!
Sensor monitor
During maintenance, the sensor
monitor allows validation of the
sensor by immersing it in a known
solution, for example, and checking
the values measured.
