Indicator type
Through different indicators,
different
measurement
ranges can be determined.
There are 5 indicator types
available. With the help of the "NEXT" key, select the indicator used in the in-
strument.

Physical unit of water hardness
Using the "NEXT" key, choose
the unit in which the water
hardness is to be displayed:
°dH, °E, °F, ppm CaCO
3
,
gpg or mmol/ltr.
Correction factor
The displayed value is influ-
enced by component toler-
ances. Also the chemical
colour reaction is influenced
e.g. by non-hardness-ions. That’s why it may be necessary to adjust the saved
absorption diagram to get an optimal result. So it is possible to change the zero
point of the absorption diagram due entering a shift value (+/- 400 units) and
to change the steepness due entering of a correction factor (0,30 – 2,00).
It is also possible to enter the shift value automatically with help of a 0° water
sample in step ‘service setting 3’. The correction factor needs to be determined
empirically with help of a known water sample.
shift value: positive value = higher water hardness
correction factor: higher than 1,0 = higher water hardness
Limit value of the water hardness
Determine the value of the
limit at which a message is to
occur when the water hard-
ness is over- or underrun (see
programme step 1.5).

Attention: The limit value of the water hardness is dependent on the choice of
the indicator type and the water hardness. Check the limit value of the water
hardness if you have changed programme step 1.1 or 1.2. If a recorder is used,
the scale in programme step 8.2 must also be re-assessed.
Limit value monitoring
It can be laid down whether the signalisation of the
limit monitoring occurs in the event of an underrun
