7 CALIBRATION AND ADJUSTMENT PROCESS
HUMOR 20
The special construction of the measuring chamber allows the calibration and
adjustment of a wide variety of measurement value sensors. From sensor probes
with a diameter of 8 - 25.5 mm
as well as those for compact (room) transmitters, data loggers, etc. with max.
dimensions 100 x 85 x 40 mm

Compact room transmitter

With the use of the Plexiglas cover of the measuring chamber included in the scope
of supply, the HUMOR 20 can also be used for the calibration and adjustment of
room devices.
Due to thermal coupling with the outside, additional measurement errors are to be
considered depending on the used humidity and the position of the specimen in the
measuring chamber. (see data sheet)
1. Apply supply voltage.
2. Position specimen in the measuring chamber.
3. Insert O-ring in the groove provided in the measuring chamber.
4. Pass connection cable through the threaded joint of the Plexiglas cover.
5. Place cover and fasten both knurled nuts tight.
6. Connect specimen to the supply connections of the HUMOR 20
(24V DC) or to an external power supply section.
7. Apply output signal of the specimen to the internal measurement
inputs of HUMOR 20 (Unit1 RH, Unit2 RH).
8. Select the measuring range according to the output signal of the
specimen. Additionally the temperture of the measuring chamber can be
displayed by selecting it with the measuring range switch.
9. Wait through stabilization time (ca. 20 min.).
10. Select the desired humidity - desired value with the controller.
11. Compare the values shown on the display with the output signal of the
measurement transmitter.
