ONE-POINT RH-CALIBRATION
The accuracy is recommended to be
checked at least once a year; the interval
depends on the operating conditions and
the required accuracy of the
measurement. The transmitter calibration
can be conveniently checked with the
HMI41 or HM70 indicator equipped with
an appropriate probe and optional
calibration cable. If adjustment is
needed, use the one-point calibration
potentiometer. If you prefer to calibrate
the HMD60U/Y transmitters against
saturated salt solutions, use LiCl (11
%RH) and NaCl (75 %RH) solutions.
REPLACEMENT OF THE HUMICAP
SENSOR AND THE FILTER
Remove the damaged sensor and insert a
new one. Recalibrate the transmitter.
Replace a dirty filter (membrane or
sintered) to ensure a maximum lifetime
and a fast response for the sensor. Do not
attempt to clean the filter.
