Accuracy of calibration 1
Normally the pump does not have to be calibrated.
The pump can be calibrated if viscous feed chemicals are
used or extremely high accuracy is required.
Accuracy of calibration 2
Calibration will not be accurate if these conditions are not
adhered to:
–
do not allow the stroke length to fall below 30%.
–
The pump should perform a minimum of 200 strokes for
calibration.

precautions when performing the following calibration
instructions. Observe the safety data sheet for the feed
chemical!
