– Switching between the metering modes means that the diaphragm
metering pump must be re-calibrated!
The calibration symbol C! is displayed on the display of the operating level.
– Once the automatic [Calibration]
has been correctly carried out, the symbol
C! is hidden in the operating level again!
– The table values displayed for the max. stroke frequency (max. metering
capacity) are dependent on the pump size and calibration.
– The details about the suction stroke and metering stroke times are
theoretical values. They may vary according to calibration tolerances,
suction line lengths, back-pressure, etc.
