Principles of Operation Teledyne API – Model T700 Dynamic Dilution Calibrator
290
10.3.7. POWER SUPPLY AND CIRCUIT BREAKER
The T700 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.
WARNING
The T700 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.
Should the power circuit breaker trip correct the condition causing this situation before
turning the calibrator back on.
