How do I test the voltage output from my resistance soldering power unit?
You can do this quite easily, using your always handy, multi-meter, with the function dial set to read AC voltage. Disconnect the handpiece from the power unit, to allow access to the output receptacles or bolts. Make sure the power unit is plugged into the footswitch and the footswitch is plugged into an active AC power outlet. Do not actuate the footswitch just yet! Turn the power unit on and turn the voltage control knob to the maximum setting. Place the multi-meter test probes into the output receptacles or onto the output bolts on the front of the power unit. With AC voltage there is no positive, or negative current to be concerned about. Actuate the footswitch and check the reading on the multi-meter to verify the power unit’s output. Adjust the voltage control knob to confirm power unit’s ability to control voltage.
