1.4.4.1 Calibration function of the combination
probe (humidity/temperature) [CAL]
Each humidity probe of Dostmann electronic is a
combination probe. That means that beside the
humidity sensor these probes also contain a tempe-
rature sensor. Both measurement values are plug-
ged 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
indicates 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 choo-
se between rH for calibration of humidity and P°C for
calibration of temperature.
Use the up and down keys [
] to select the reque-
sted calibration option. Push [ENTER/MENUE] to
confirm.
