Overtravel Adjustment Prior to returning the pressure switch to service, it is necessary to perform overtravel calibration as follows:  Connect the pressure switch to a suitable controllable pressure source. Apply pressure to a value above the adjustable range. (This ensures maximum piston travel.) Do not exceed overrange.  Connect a continuity tester, ohmmeter or test light to the C-common and NO-Normally Open contacts.
