"...First of all it is TRMS. It tests AC/DC voltage to 1000V and AC/DC amps to 600A, and also handles millivolts...." Read more

"...I found the meter would "drift" a lot and not stay zero'd. It would sometimes drift as much as 0.2A and I was having to constantly re-zero it...." Read more

"...This one seems accurate at the DC amperage readings - but I cannot emphasize enough... READ THE MANUAL...." Read more

"...Happy to report that it measures capacitance accurately :)The only thing I’ll criticize is the case...." Read more

27 customers mention15 positive12 negative

Customers are mixed about the readability of the electric circuit testing device. Some mention that the display is good and easy to read, while others say that it doesn't give good readings at all. The numbers jump around and never settle in on an accurate reading.

Not good for ohming sensors
4 Stars
Not good for ohming sensors
I really like this meter. How it looks how it feels when you grip it - Checks alot of boxes for me. But if you're ohming anything out besides an element or coil under 100 ohms it's a bust. Pretty tired of seeing OL and having to break out the Fluke.
