The CAL-segment and the small 2 on the left indicates
to the user that oP2 is activated.
1.4.4.1 Calibration function of the combination
probe (humidity/temperature) [CAL]
Each humidity probe is a combination probe.
That means that beside the humidity sensor these
probes also contain a temperature sensor. Both
measurement values are plugged in the same
channel over one probe. Before the calibrating of both
measurement values (humidity and temperature)
the calibrated measurement value must be adjusted at
the menu item Prob (Probe selection 1.4.2).
The instruments offer three calibration options:
1) [OFF]:Standard characteristic curve (no specific
probes correction will be carried out)
2) [OP1]:Calibration by code (2 x four digit code) is
equivalent to a 2-point calibration
The code is marked clearly by a label on each stan-
dard probe/rH = humidity & P°C = temperature.
3) [OP2]:Calibration by physical standard references (1-
point, 2-point or 3-point calibration) is only for the
measurement value rH humidity possible
CAL = calibration
Push [ENTER/MENUE] to calibrate the instrument with
sensor. Use the up and down keys [
] to
select CAL. Push again [ENTER/MENUE]. On the
left corner of the display appears a small 1, which indi-
cates the selected channel. For changing the channel
use the up and down keys [
] . Push [ENTER/
MENUE] to confirm.
With the up and down keys [
] you can now choose
between rH for calibration of humidity and P°C for cali-
bration of temperature.
Use the up and down keys [
] to select the request-
ed calibration option. Push [ENTER/MENUE] to confirm.
