Zeroing Pressure Gauge

With the pressure system shut off and the pressure gauge in a vertical position, vent the gauge to the atmosphere by disconnecting the pressure line (A). Using the zero adjusting screw (B), zero the gauge by setting the indicating pointer exactly on the zero mark. Connect the lines and start up the pressure system.
