Temp Probe Adjustment
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 when the process temperature
is precisely measured using a cali-
brated reference thermometer! The
measurement error of the reference
thermometer should be less than
0.1 °C. Adjustment without precise
measurement might result in consid-
erable deviations of the measured
value display!
Sensor Monitor

measured-value processing.
