3) Connect pressure hoses, fittings & pumps (if required) to the
pressure instrument to be checked.
4) Move the switch on the Pressure Module to PSI and press the
E-Z Dial knob on the 820-ELITE.
5) Press and hold the e E-Z DIAL KNOB for 1 second to 'Zero'
the pressure. The word "TARE" appears on the display indicating
that all measurements are relative to the pressure measured
when the calibrator was zeroed.
Pressure readings appear on the display of the 820-ELITE and
are constantly updated.
The PIE 820-ELITE measures the pressure and constantly
updates the display with the current reading. Move the
EZ-CHECK switch
q to MAX to see the highest reading and to
MIN to see the lowest reading. Press and hold the knob e for 2
seconds to clear the MAX and MIN readings.
