The pump can also be operated in the calibrated state. In this case, the
corresponding continuous displays then indicate the metering volume or
the capacity directly.
Accuracy of the calibration
The calibration will not be accurate, if these conditions are
not adhered to:
–
Operate with at least 30 % stroke length.
–
The pump should operate at maximum frequency.
WARNING!
If the feed chemical is dangerous, take appropriate safety
precautions when executing the following calibration instruc‐
tions.
Observe the safety data sheet for the feed chemical!
1. Lead the suction hose into a measuring cylinder containing the feed
chemical - the discharge hose must be installed in a permanent
manner (operating pressure, ...!).
2. Prime using the feed chemical (simultaneously press the two
[arrow keys]
), should the suction hose be empty.
3. Record the level in the measuring cylinder.
4.

pressing the
[P/OK]
key.
9. Determine the required metering volume (difference initial volume -
residual volume).
