Will this detect presence/absence of power in electric company feed cable at meter on a house?

It should if it's just in jacket and not in a pipe. Make sure you test it on known powered wire first to make sure the batteries are good.

It will tell if there is voltage present. Just touch the outermost edge of both sides of the cable to make sure you have voltage on both phases.

This is a Voltage detector, It "will" detect voltage regardless of where it is used, However, it haslimitations, the lower voltage limit, and the Upper voltage limit.also, it is battery powered, so you (SHOULD) test it on a known LIVE source to test it,then use it on your item. It should be used often to gain confidence, as it could NOTwork, and you think it's OK to work on something, and it's STILL LIVE, but this detector,Did NOT indicate it is LIVE ! Just be Careful. You are trusting this with your LIFE !!!!

Yes it will test for power as well as continuity just make certain to read the directions to confirm the color and sound that goes with each.

You were thinking maybe the light is psychic and would know when the power has gone off without a wired connection?

No it will detect voltage but not low voltage If there is a power surge it will protect your electrical system in you RV.

YES and suggest a GFI circuit. Remember to reset the "clock portion" if you have power outages.

I believe it will function adequately as a stand-alone detector on battery. However, the wiring provides a means to integrate this unit with a whole-house, multi-zone (upstairs/downstairs or a moderately large floor plan) protection system.

If it has 2 prongs. The temperature controller really works best monitoring small confined spaces.

You don't test continuity on an energized circuit. You can test the voltage on any part of the circuit with this meter. Be safe.

Yup, sure does! You just have to be home to activate it since the meter only broadcasts for 4 mins. when a tech turns it on.

It will measure the kWh used by whatever is pluged in to it. It will also aggregate the total kWh used for a period of time. I used it for deciding how big of a ups I need for my nas and router.

I'm not sure, I use it for phone and Ethernet cables checking, but I would say no. This is an inexpensive device. Primarily for checking the quality of cable by placing device on one end and its remote terminator on the far end. To check live data you would need something more sophisticated.

Take a digital Volt meter and it will tell you if it is positive of negative.Don

It will monitor total wattage. But you will know how much each individual device consume once you turn it on.

No. It only responds to low-frequency AC and alternating magnetic fields. A smart meter would radiate much higher frequencies.

Yes this application should be fine just remember to limit the current through each meter to no more than 40 to 50 amps. I use one of these between my power supply and my name brand power strip with power pole connectors for my amateur radio staion and whatever else I work on. D Coffey

Yes , this meter will do this, plus it is capable of using for many other electrical measurements.I really like mine

My experience is that the sensor must be very close to the transmitted signal. My opinion is it would not work for cable behind wallboard, etc. Could be a help in sorting out cables you can touch.
