evaporation rate = 1ml/min

ow rate = 1ml/min

[ml/min] = a single number (int or oat) representing the desired ow rate

[min or *] = the number of minutes to run or (*) indenitely

A negative value for ml/min = reverse

DC,? reports maximum possible ow rate

The maximum ow rate is determinded after calibration.

If the owrate entered is to fast the EZO-PMP

will send and error.
