I know lots of formulas relating to electricity and electronics........including Watts Law. But what does that have to do with my device that makes it easier to take various measurements???

I put together a real simple device that lets you easily measure Voltage, Current and Resistance of the device in question. Comes in real handy for anything you want to test, up to 15 amps in my case.

i don't really follow what the purpose is . . . . .?



i'm fond of clamp meters, and easiest way to do this is to remove the panel cover or the device you're connecting to and measure V and I.

i have a meter specifically for VD that shows the % under FLC, and current droop, and measures CB open times.

I have another meter for R.



I wouldn't use anything that leaves terminals exposed unless you have someone to stand watch until the device is safely removed/installed (learned that the hard way).

AGAIN, that is the point..........not having to remove anything to test VIR............just like the 40 dollar Kill-A-Watt device, except this one was 5 bucks. And I left an area FOR A CLAMP ON METER IF NEEDED.

All some of us have been saying is that there are numerous devices on the market, some cheap and some expensive, that can do exactly what you have mentioned, including clamp-on readers that incorporate full-fucntion multimeters, plus thermometers.

I Have ALL that stuff, this is just an additional tool that was about 5 bucks to make.
