PORTABLE OPERATION CHECKER

PROBLEM TO BE SOLVED: To provide a portable operation checker which can be carried around and is capable of checking, as required, operation of electric circuits or devices that operate on high voltage.SOLUTION: A portable operation checker includes a portable exterior casing which houses a power supply unit, an AC generator having an AC generation circuit which uses a battery as a power supply, and a booster circuit which boosts voltage generated by the AC generation circuit to obtain check voltage for checking an electric circuit or device that operates on high voltage. When in use, the check voltage is obtained by boosting the voltage generated by the AC generation circuit with the battery power supply using the booster circuit. The check voltage is applied to an electric circuit or device that operates on high voltage to check the operation thereof.
