Replacing the Humidity Absorber

The instrument continuously measures the humidity and tempera-
ture inside the turbidimeter housing and calculates the dew point
based on these values. The dew point gives an indication of wheth-
er the humidity absorber still has sufficient capacity to prevent con-
densation inside the housing.
The dew point is visible in menu <Diagnostics>/<Sensors>/<Mis-
cellaneous>.
The user is automatically prompted to replace the humidity absorb-
er when the dew point exceeds the following limits:
 If the dew point is 3 °C or higher, maintenance message E068
"Replace absorber" appears. The instrument continues to
measure normally, but the humidity absorber should be re-
placed as soon as possible.
 If the dew point is 5 °C or higher, error message E006 "Ab-
sorber exhausted" appears. The instrument stops measuring
and the humidity absorber must be replaced immediately.
CAUTION
If the humidity absorber is not replaced in time, condensa-
tion may occur inside the housing.
This condensation can lead to incorrect measurements and
failure of the instrument.
 Replace the humidity absorber when prompted.
NOTICE: The color indicator of the humidity absorber is
no longer relevant for newer instruments with dew point
calculation.
