3-9. EMERGENCY BREATHING APPARATUS (EBA) MAINTENANCE INSTRUCTIONS. (CONT)
CAUTION
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
NOTE
Perform the static pressure test at the interval specified in the Unit PMCS table, after maintenance as
specified, or when equipment damage is suspected
a.
If necessary, zero flow gauge (1) and pressure gauge (2) by turning adjusting screws (3) at the bottom front of
each gauge until the indicator needles point to zero
b.
Ensure flow valve (4) is closed by turning it clockwise
CAUTION
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
c.
Plug electrical connection (5) into an electrical outlet
NOTE
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
d.
Check the calibration of the regulator tester as follows:
(1)
Remove any adaptors from inlet connection (6)
(2)
Turn the regulator tester on by depressing on/off switch (7)
(3)
Open flow valve (4) until pressure gauge (2) reading is -3 inches of water.
