Calibration Pump With Oval Gear Meter (Ogm ); Preparation - Ecolab Elados EMP IV E60 Notice Technique

10.4.3 Calibration pump with oval gear meter (OGM
If a dongle plate and an oval gear meter are connected and the "oval gear meter" function
(see chapter 10.3.11) is activated, the oval gear meter pulse rate recorded is automatically
displayed at the end of the calibration process.
This is offset against the specified calibration value. A correlation thus occurs between the
oval gear meter pulses and the metered quantity.

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.
By activating the 'Menu/Exit' function, the running calibration can be interrupted.
NOTE
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
This quantity is then entered as the calibration value (in ml or l).

The volume of the measuring cylinder
should be 1/50 of the metering pump rate in
litres/h.
During this process, the suction tube 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.
