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.
WARNING!
If the feed chemical is dangerous, take appropriate safety
precautions when performing the following calibration
instructions. Observe the safety data sheet for the feed
