4a. In the pump’s Seconds mode, select a maximum operating time that is greater than or equal to the injection time calculated in 3.
4b. Calculate the percentage the injection time is of the maximum operating time selected in 4a.
x% = injection time/max. operating time x 100
The injection time cannot be less than 10% of the pump’s maximum operating time.
Set the percentage.
