Regulator tester damage. Do not operate the regulator tester unless a test regulator is attached to the
tester inlet connection. Operating the regulator tester with an open inlet connection will contaminate the
flow orifice and cause the flow gauge to produce inaccurate readings. The only time the regulator tester
should be operated with an open inlet connection is when the calibration is being checked and this time
should be minimized
Perform the air flow performance test at the interval specified in the Unit PMCS table, after maintenance
as specified, or when equipment damage is suspected
If necessary, zero flow gauge (1) and pressure gauge (2) by turning adjusting screws (3) at the bottom front
of each gauge until indicator needles point to zero.
Ensure flow valve (4) is closed by turning it clockwise.
Damage to electrical equipment. Use only a grounded 110 volt AC 60 cycle electrical power source for the
regulator tester to avoid damaging internal electrical components
Plug electrical connection (5) into an electrical outlet.
Check the calibration of and leak test the regulator tester upon receipt and every 30 days or every 50
regulators tested, whichever comes first, or when inaccurate performance is suspected
Check the calibration of the regulator tester as follows:
Remove any adaptors from inlet connection (6).
Turn the regulator tester on by depressing on/off switch (7).
Open flow valve (4) until pressure gauge (2) reading is -3 inches of water.
The hand-written flow gauge value may differ from tester to tester.
