6.4.4.1 Calibration function combined probe (humidity/temperature), CAL
All humidity probes by WIKA are combined probes.
This means that besides the humidity sensor they also contain a temperature sensor.
Both measurement parameters are connected to the same measuring channel using one
probe connector. To calibrate both measurement parameters, humidity and temperature,
the measurement parameter
rH
(rel. humidity) must first be set (see chapter 6.4.2 “Probe
selection Prob”).
The instrument has 3 different calibration modes:
OFF
Standard characteristic curve
no probe-specific correction is performed
oP1
Calibration by code
The 2 x 4-digit code, clearly and visibly displayed on the handles of our probes
(
rH
= humidity and
P °C
= temperature), corresponds to a 2-point calibration
oP2
Physical calibration
Calibration with reference standards: 1-point, 2-point or 3-point calibration is
only possible for the measurement parameter
rH
humidity.
CAL = calibrate
