7.2 Check calibration
In check calibration, the calibration value is calculated
by reading the consumption of chemical in a specific
period and comparing this with the number of dosing
strokes performed in the same period.
This calibration method is very accurate and
especially suitable for check calibration after long
periods of operation or if direct calibration is
impossible. The calibration can for instance be
carried out when the chemical tank is replaced or
filled.
To carry out a check calibration, proceed as follows:
1. Stop the pump by pressing the
2. Read the counter and note the number of dosing
strokes, see section Counters.
3. Read and note the quantity in the chemical tank.
4. Start the pump by pressing the
it run for at least 1 hour. The longer the pump is
operating, the more accurate the calibration will
be.
5. Stop the pump by pressing the
6. Read the counter and note the number of dosing
strokes, see section Counters.
7. Read and note the quantity in the chemical tank.
8. Calculate the dosed quantity in ml and the number
of dosing strokes performed during the operating
period.
9. Calculate the calibration value as follows: (dosed
quantity in ml/dosing strokes) x 100.
10. Set the calculated value in the calibration menu.
