    Can AAA lithium batteries be used in this device? Also, can rechargeable batteries be used in it? I don?t want to use alkaline AA batteries and wind up with a leak that damages an expensive device.

        Answer This Question

        The capacitance setting on the dial is between the temperature and frequency settings. The meter will auto-range to display the measurement in the most appropriate range. Please see the Instructions / Assembly document under Additional Resources From the Manufacturer for full instructions.

            Wmcksmith, how does it work without batteries if you are testing a receptacle that typically would not be outputting any power if it is being troubleshooted? I think you answered "no" too quickly and should correct it not to mislead anyone.

            This tester is not like the ones with 3 lights that you have to look on the chart to decipher the state of the wiring. This unit has an LCD display that tells you the state of the wiring in writting word. It requires batteries to operate.

              If it doesn’t light up the plug isn’t connected to power.

                  No batteries. Uses the power from the receptacle.

                    Yes. The testing device requires batteries.

                      Requires batteries  But Not complicated works very well very handy and my retired. Electrician friend was impressed by it. If you forget to turn off the batteries, it will shut itself off, so I wouldn’t let the batteries be a big concern.
