Note!
The hardness of the water is not significant, since the adjustment takes place using pure water – with-
out the addition of the indicator. The accuracy of the measurement is not dependent on this adjust-
ment either, since the measurement is based on the recognition of a colour change (indicator transi-
tion). For each measurement a blank value i.e. a measurement without indicator is conducted. During
the addition of the indicator, the relative alteration in brightness within the measuring chamber is the
basis for the measurement of the colour change.
For the electrical measurement, however, a minimum brightness is required. The calibration value
must therefore lie over 50 %. Otherwise, the error message "Blank value too low" occurs on meas-
urement.

If you get the unit delivered it is calibrated optimal. Different water components and tolerances during
the production the indicator may require that the units needs to calibrated after delivering to get opti-
mal display results. Therefore it is possible to enter shift values and correction factors in program step
3.1 to calibrate the absorption diagram. It is also possible to determine and adopt the shift value
automatically in service step 3. The correction factor can only be determined with help of a known
water sample.

sensible. Repeat the measurement some times. During this process differences of +/- 50 units might
be possible. Choose an average value. This adjustment should be carried out after the unit is already
some days in use and not after the very first start of the unit.
Test of the output relays
Using the
"KEY"
key, you can activate the key function
"TEST"
for the
"F3"
key in the output setting
of the analyser (no analysis sequence). Press the key function
"TEST".
After approx. 4 seconds, the
analyser switches into the test setting.

In this setting, you can select the 3 output relays consecutively via the
"
"
key and activate and deac-
tivate them with the "TEST" key. In programme step 5.4, it is determined whether, when activated, the
relay concerned is in the operative or inoperative state..
You quit the test setting by pressing the "END" key. The test mode is automatically exited 2 minutes af-
ter the last operation.
After quitting the test function, the relays are switched back into their states before the test.
ATTENTION! Bear in mind the possible consequences of an activation: e.g. error mes-
sage in the central control room, start of a regeneration, shutdown of a boiler plant etc.
Therefore, the testing of the operational capability of the output relays should only be performed by
trained staff.
