MICRO AMP TEST METER LESS ENCLOSURE
(DUAL SCALE-PROTECTIVE CIRCUIT)
The MICRO AMP TEST METER may be used to adjust the flame and position the flame sensor for
maximum signal strength The METER allows reading the flame signal strength from both ultra-violet
scanners and flame rods (See PROTECTOFIER Service Manual PSM-1187) The 0-200μA
scale Is used when using the P-C II. P-C II W, or P-C II WRA ultra-violet scanners The 0-50μA scale
Is used when using a flame rod The factory-installed Jumper on the METER between terminals A&B
should be removed when a flame rod Is used in order to utilize the 0 to 50μA scale
The METER includes a protective circuit to guard against damaging the METER should the wire
leading to the signal source be accidentally grounded (or should the flame rod be grounded) The
METER also includes a needle dampening circuit which allows easier reading of the METER with
the fluctuating signal of a U-V scanner
A test plug assembly (optional) may be used with nng tong terminals connected to the studs of the
METER The test plug Is plugged directly In the "μA TEST" Jack on the PROTECTOFIER chassis
