タの電源回路。 In the pressure tester power supply circuit that supplies power from the battery to the pressure tester electronic circuit via the main switch, there is a latching relay installed between the main switch and the pressure tester electronic circuit, and a winding that turns on the latching relay. A latching relay closing circuit that flows a current for a predetermined period of time after the main switch is turned on, and a latching relay that flows a current through a winding that monitors the pressure generated by the pressure tester and turns off the latching relay for a certain period of time when the pressure tester is not in use. A power supply circuit for a pressure tester, comprising a cutoff circuit.
