Measurement:
Note the operating pressure indicated on the pressure switch.
Allow fan to run.
Once fan begins to run increase the pressure via
the syringe to that indicated on the pressure switch.
Sparking should then be observed through the sight glass.
Note:
If sparking is not observed it is permissible to increase the pressure by 50%.
100 Pascals = 1mbar / 50 Pascals = 0.5mbar
