I didn't pay for or expect a professional quality meter when I bought this one to replace one which had gotten run over. But I was a bit disappointed. Although the meter does what it says it will, the refresh rate, especially on RPM makes it all but useless. Also the auto ranging takes forever to settle down. The case is cheap and too small for the meter and accessories and the alligator clips are completely useless. On the other hand, it is a fair meter for the weekend warrior or casual car restorer like myself. Don't think I would buy another.

Not overly impressed!! the software doesn't work not sure if it's defective or outdated contacted OTC going to be over month to get a replacement, the hook for PC most laptops don't have so unless your going to drag a desktop around you shop you can't use this function.

I don't know what it is but I've never seen a digital meter with a functional Dwell function, this being yet another. Maybe it hooks up differently than my cheap analog dwell meter that does work.
The RPM pick-up and function is useless as well; it's very erratic and incomprehensible.
It seems as though the 'refresh rate' or 'sampling rate' of this meter is very slow, (seen during RPM function?). During starter voltage drop testing I find myself having to 'hold crank' an extra second or two than what I'm used to otherwise I get no reading, both min/max or standard readout.
I didn't like the 'auto-off' feature at first but I found that, during amperage draw testing, the circuit stays intact when it shuts off. A button press turns it back on.

This is 'out of the box' function. I have not done any research or user manual reading to see if better performance can be achieved.

over priced, what else can I say? It does all the basic functions you would expect of even a cheap multimeter, but it doesn't do a very good job at the more automotive specific ones that it lists.

I bought this as a inexpensive option to more expensive Multimeters and found that it works great. The software is very helpful as well at the probe. Would recommend for a first meter.
