In this setting it is possible to switch the metering (dosing) pump on and off in order to pump indicator into
the measuring chamber. Further functions are not activated.
This procedure is necessary if air exists in the connecting hoses between the indicator bottle and the measur-
ing chamber. This means: always on commissioning and after the hoses are replaced. Owing to the low de-
livery rate of the metering pump, this procedure takes approx. 120 seconds if the hoses are empty.
Move the cursor with the aid of the

key under Y for Yes or N for No, in order to switch the pump on or
off.
Note:
On refilling the indicator after a display that the indicator is deficient, this procedure need not be initiated, since the instrument stops the
automatic analysis sequence in good time.

A calibration is necessary after electronic components in the control unit are replaced and after the replace-
ment of the transmitter or receiver sensor of the optical measuring section (gauge length).
After cleaning the measuring section or the sensors, the setting should be checked and corrected if neces-
sary.
If, using the

key, you move the cursor under Y for "Yes", the measuring chamber is first of all rinsed
(flushed) and filled with clear water. This procedure lasts about 20 seconds and can be repeated as opften
as desired by switching back temporarily to "No".
After this, a display appears in the range from 0-121%.
