volts and amps with CT!

I love Chinese spelling:

Accrancy:1%±2 words
Speed:2 per/second

WTH do those things mean?

For 12 bucks, even if it's inaccurate, it looks nice...lol

And, yeah, I bought a few AC volt/amp meters a few years ago for my home gen setup, liked them so well I bought a another one for my RV..

Got the 30A ones for $9 back then, now I see only 100A versions for a bit more..

I added extra wire length to the CT to allow for remote mounting the meter.

My RV since it stays plugged in 24/7 at home I put a small toggle switch nearby to turn the meter off when not needed.. Svaes unwanted wear and tear on the backlight since the backlight stays on as long as the meter has power.

I also see there is Three Phase versions which I suspect might be adaptable for a 50A shore connection (ignore L3) which would eliminate the need to buy two meters for that setup.

That one is 92 bucks from Dell City. A witch is about 5 bucks....

Under brand it says "does not apply"

so it's sensing line voltage and current, using nothing but a current transformer? that's pretty cool. how does that work exactly? voltage is a potential, so what's the other reference?

The schematic shows an AC power connection.

Came with my PI EMS. No need for a second meter.
