When running a calibration dose it should be run in the duty configuration and
with the duty fluid. The program will run the pump for up to four minutes or you can
Stop it sooner, however the longer you allow it to run the better. The minimum run
time should be 15 seconds or 10 revolutions of the rotor. You can enter the value
of the calibration run in ml. On completion of the procedure the screen will
confirm the calibration figures and will also confirm the selection as well as
displaying the maximum allowable rpm.
