TEST. (Cont)
c.
Connect low-pressure switch to dead weight gage tester or a calibrated pressure gage with a
source of hydraulic or pneumatic pressure.
d.
Apply 11 psi (78.85 kPa) to low-pressure switch as indicated by dead weight gage tester or
calibrated pressure gage.
(1)
If multimeter indicates infinite ohms, go to step e.
(2)
If multimeter indicates 0 ohm, calibrate low-pressure switch.
(3)
If low-pressure switch cannot be calibrated, disassemble low-pressure switch and replace faulty
components.
e.
Apply 10 psi (68.95 kPa) to low-pressure switch as indicated by dead weight gage tester or
calibrated pressure gage.
(1)
If multimeter indicates 0 ohm, test is complete. Disconnect multimeter and position cover
gasket (4), cover (3), and free end of retainer (5) on housing (7) and install four
lockwashers (2) and screws (1).
(2)
