M703E Calibrator Operator’s Manual
Theory of Operation
9.2.5. POWER SUPPLY AND CIRCUIT BREAKER
The M703E calibrator operates in two main AC power ranges: 100-120 VAC and 220-240 VAC (both ± 10%)
between 47 and 63 Hz. A 5 ampere circuit breaker is built into the ON/OFF switch. In case of a wiring fault or
incorrect supply power, the circuit breaker will automatically turn off the calibrator.
between 47 and 63 Hz. A 5 ampere circuit breaker is built into the ON/OFF switch. In case of a wiring fault or
incorrect supply power, the circuit breaker will automatically turn off the calibrator.
NOTE:
The M703E calibrator is equipped with a universal power supply that allows it to accept any AC power
configuration, within the limits specified in Table 2-2.
CAUTION
Should the power circuit breaker trip correct the condition causing this situation before
turning the calibrator back on.
