Condor MDR 2 pressure adjustment
by: Bill

This from their technical bulletin:

When the main pressure spring is adjusted, the cut-in and cut-out value of all
pressure switches change proportionally. In other words, the differential
pressure remains the same.

If the range between cut-in and cut-out value is to be increased, the differential pressure screw must be used.

When carrying out a differential pressure adjustment on the pressure switch
types MDR 1, MDR 11, MDR 2 and MDR 21 the cut-out pressure value changes and the cut-in pressure value remains constant.
