Am i right that this meter clamp can only read up to 40 amp ac. I need one just like this but goe...

Asked by PopaBear September 8, 2020
2
Answers

It is rated for 400 amps but if you use a line splitter to measure a corded appliance it multiplies the reading 10X and so would max out at 400 amps which would indicate 40 actual amps. But for straight line readings it should read up to 400 amps.

Well made with useful features. Easy to read outputs and well laid out controls. Should include a line splitter for reading AMPS from appliances and devices and would have liked that the case be a bit larger to accommodate accessories such as the splitter. Overall though a good buy and recommended.
