12. 2-point (optionally 3-point) calibration
To do so: Calibration equipment (art.no.10072) and calibration ampoules (humidity
standards art.no.10005) required. The device, the calibration equipment and the humi-
dity standards must have a temperature between 20.0 °C and 26.0 °C. It is recommen-
ded to store the device, the calibration equipment and the calibration ampoules in a
room with little temperature fluctuation for 24 hours.
12.1 Assembling the calibration equipment
1. Insert the first sealing ring
(1) (figure 64 ) into the up-
per part of the calibration
equipment (figure
65 ).
2. Insert the sword sensor
into the upper part of the
calibration equipment (figure
66 ).
3. Insert the second sealing ring (2) (figure 64 ) into the
upper part of the calibration equipment (figure 67 ).
4. Put the textile pad in the lower part (figure 68 )
and carefully pour the humidity standard onto
the pad, beginning with the humidity standard
of 35 % relative humidity.
5. Put the third sealing ring (4) (figure 64 ) onto
the lower part (figure 69 ), then put the alumi-
nium disc (3) onto it (figure 64 ).
6. Carefully place the upper part together with
the RH5 or RH5.1 sword probe on the lower
part (figure
70 ).
7. Recommendation: First screw the lower part
lying on the table counterclockwise into the
upper part and lift it straight to complete the
screwing.
» Take care to lift the RH5 or RH5.1 device with
calibration equipment straight up and not to
tilt or turn it over. Otherwise the sensor may
be damaged.
