Great vid, Thanks!

Lots of questions about why LoZ was in DC mode in some parts of the video. This is normal when the voltage is zero. This meter auto-selects AC or DC. If the voltage is zero, it starts off in DC and switches to AC when it detects AC voltage.

AhhhhHA! Thankyou! I live off grid and have my own power station. Solar, generator, batteries and inverter. With an my old inverter I would get 90 volts on the ground even though no grounds were hooked up. Drove me nuts. Never tested if there was any current behind it but it never seemed to cause any issues. I thought maybe it was comming from utility transimission lines that are nearby and effecting my direct burial cable.

You just make a lamp holder with a filament lamp (old style lamp) connected with two wires about 1m long with leads at the end..This is 100% precise find Phase and Neutral easy..

For sure an incandescent bulb will knock down a ghost voltage in a heartbeat.

I read somewhere that it's possible to use a 3000 ohm resister and make an adapter to convert your regular non LoZ meter to operate in the same manner as a LoZ meter. Possible and if so, can you show how to make one? I have a couple meters with the LoZ feature but I also have a few without it and it would be great to have an adapter to detect ghost voltage. Thanks, enjoy your videos 👍😎🤠🇺🇲

Yes you can but you would want to use a thermistor instead of a resistor because a significant amount of heat is dissipated from the resistance across the leads when measuring higher voltages for extended periods of time. The thermistor should be a PTC type so that it's resistance increases as it warms up thereby reducing the amount of heat that It ultimately dissipates if left connected to the voltage source. I'll definitely consider making a video to that effect.

I don't have a loZ meter. I was troubleshooting wiring at my brothers house. The new LED lights in the Kitchen stay on, but are very dim when the switch is turned off. The house is very old and the wiring is messed up. The hot for the light stays hot. The neutral gets switched. We have no idea where the the how and neutral are spliced back. Would induction be enough to dimly light an LED bulb? We are at a loss.

Yes, induction or capacitive coupling could do it. Also, if you are using a dimer switch - many of them don't well support LED lighting.
