Variable
The theoretical value moved with one complete rotation of the pump is 0.6944 cc,
measured with water at an approximate temperature of 25 °C.
Dispensing 1 cc of product requires 576.05346 steps of a pump’s stepper motor. This
is the value programmed in the software as being the standard” calibration value.
