Recently I just bought a used DOS pump from a friend. After read through instructions to calibrate both pumps...both came out good 3 times...right on the scale.
When i go program to dose 40ml, it only dose 20ml, 1 time with 15ml.
I try too many times, no expectations meet. Also I noticed when it's on, the pump runs slower speed than when it was in calibration, probably haft of a speed.
What do I do wrong?
Need some guidance please.
