hi
procedure for calibration of pressure switch

for the pressur eswitch some set point is given for eg:
10 psi
so when we apply pressure to the pressur eswitch it should
get activated for that set point
the result sheet is written as

set point pre calibration post calibration
activation 10 psi 24 psi 10 psi
deactivation 30 psi 12 psi

the pressure switch adjustment is by some abjustment screw
or knob or according to the adjustment given in the preesur
eswithch.
