Schematic that shows a DPST switch and 2 voltage regulator.s
SRS SR620 frequency counter behaving erratically when powering up: the LEDs light up, but then it starts switching off and you can hear relays toggling all the time. When it does work, it seems to go bad again when you touch the power on/off button.
