10.4.3.1 Preparation
Fig. 10.57 Calibration /pump with oval gear meter (OGM
PLUS
): Preparation
Connect pump ready for operation on pressure side
(see chapter
7 “Installing the device”).
Fill a suitable measuring cylinder
and insert the suction line.
NOTE
The volume of the measuring cylinder should be 1/50 of the metering pump rate in litres/h.
During this process, the suction line must not change its position.
The calibration of the metering pump is only valid for the currently set stroke length setting.
After changing the stroke length, the calibration must be performed again.
10.4.3.2 Calibration / Start
Fig. 10.58 Calibration / Start
to : The pump runs 122 strokes (ca. 1 min).
The strokes are counted down from 122 to 0.
The oval gear meter pulses (OGM pulses) are counted upwards from 0.
NOTE
By activating the 'Menu/Exit’ function, the running calibration can be interrupted.
If the OGM pulses are not displayed, check all the connections to the pump!
to : After the running process, the amount removed from the measuring cylinder
(see chapter
10.4.2.1 “Preparation”) must be read off.
This quantity is then entered as the calibration value (in ml or l).

During the calibration process, the oval gear pulses
determined appear on the display.
