5
– 300 sec, default 30 sec
Used to flatten noisy signals.
The longer the filter time constant, the slower the
system reacts to changes in the measured value.

– 6000 sec, default 300 sec
During calibration, signal outputs and alarms are
deactivated. With
Hold Time after Calibration , this
period can be extended until stable values are
measured.
0.00
– 14.00 pH, default 7.00 pH
If the instrument is used
without pH sensor (Sen-
sors 5.1.2 pH Electrode without ), enter pH value
for pH compensation. Normally, this is a known,
stable pH value, or it is determined by means of a
pH meter such as CHEMATEST 25 from SWAN.

not displayed if the instrument is
