temperatures and humidities are constantly measured the housing should not
be exposed to direct sunlight or heat radiation.
3.4 Humidity measurements
Humidity measurements are activated when the ± key in the Singal menu
is repeatedly pressed until the text “Humidity” appears with the unit of
measurement “%”. The ENTER key confirms the selected measuring mode
and returns to the display. The diffusion aperture on the rear of the housing
should not be obstructed. The humidity sensor is a laser-trimmed, capacitive
sensor element with chip-integrated signal processing. It can be retrofitted or
replaced by the user as well (order no. 7203) after the two calibration values
Zero offset (here 0.833 V, Figure 6) and Slope (here 31.31 mV) have been
entered under the Setup menu.
Figure 3.3 – Position of the humidity sensor when the battery compartment
cover is removed.
The slope value taken from the provided calibration record must be rounded
off to two decimal places (here 31.311 mV —> 31.31 mV).
