2in1 22mm AC50-500V 0-100A Amp Voltmeter Ammeter Voltage Current Meter With CT Au23

this doesn't make much sense. current transformer connects. but how does it measure voltage?

what is the lowest current that counts

Can I use this on a hoverboard to know the battery status?

Will this work on 12v dc system?

if I'm powering this from the load side of a relay will the constant on/off of power cause any problems? i'm trying to monitor a small motor.

I let a main cable pass trough the coil, but doesn't work at all. Leds don't light. What i'm doing wrong?

I tried to connect it and it does not work . can you please show how to connect it

Is it measure DC voltage and current?

As soon as I connect two back screws to 235V AC, it work for 5 sec and stop.What I done wrong ?

Can I make the wire between the ct and display longer?

What are the dimensions of the coil?

Does the current transformer for ampere measurement come together or is it sold separately?

how accurate is this???

does it also measure three-phase current?

received gauge, no wiring diagram with it. two screws on back under blue cover labeled 1X and 2X, which one is the positive side?

quel câble doit passer dans l'anneau ? + ou -. puis je rallonger le câble sans distorsion du résultat ? faut-il absolument que le câble fasse des tours de l'anneau, car mon câble est rigide, câble d'un moteur de 3000w de trottinette ? merci

I need only voltage, no need to measure current, so can I use this product.

Please send me a drawing how to connect this to the electric wiring .
