Review on DROK Multimeter Voltmeter Transformer Two Wires by Jason Hinrichs

I tested this with a Klein CL700 clamp meter and found that even at the minimum current setting the meter was consistently a little too high, maybe as much as 10%. That's fine for my application, which uses it to monitor generator load, but you have to know that you get what you pay for with this meter. Because of the size, I was able to widen a regular dimmer wall plate a bit and easily fit this meter in the hole. The pictures are not very clear, but the voltage and current adjustment potentiometers are INSIDE the back of the unit. To access them you have to remove the back cover.
