Extech 380941 High Resolution Mini 200A AC/DC Clamp Meter - Professional Electrical Testing Tool for HVAC, Automotive & Industrial Use

I did not have a clamp meter for home use previously but have used current clamps in the past at work for measuring inrush currents and current draws on power supplies which were done using multi-thousand dollar Tektronix equipment. And while I haven't compared this clamp meter to a reference like that there are videos of others doing similar things on youtube that show how accurate these little meters are. This one is set apart from most others in that it will measure DC current and temperature which not all clamp meters will do and I wanted an all-in-one solution to replace my circa 1980's Micronta true RMS multi-meter.It is nicely built with a solid feel and a good albeit single line display. Ergonomically it has nice graphics with good legend contrast except for one area. The rotary switch. While the action of the switch has great feel with firm detents for each position and a nice knurled and rubberized outer ring it has a position indicator that is a short pointer bar recessed into the top of the green part of the switch. It is very difficult to tell what it is pointing to unless you have good light. I'm sure Extech decided that the tooling and manufacturing cost of having of a double-shot version with a high contrast indicator would be too much for the price point they were shooting for on this meter. As compromises go this is a good one in my view.Functionally the meter has everything one is likely to need and for home use its accuracy is more than adequate. AC voltage and current readings are true RMS with crest factor adjustment percentages listed in the manual for those who want to measure non-sinusoidal waveforms and who care about such things.I had an issue recently with my heat pump. The service technician had a Fluke clamp meter and I though this would be a good opportunity to compare the Extech to the much more expensive Fluke. So we measured the current of the compressor motor and both meters read essentially the same (within a 100mA of each other) on a 12A reading. We did some voltage readings as well and found those to be virtually identical. Not bad!Over the last couple of months since I received the Extech MA445 I've measured precision resistors, film caps, temps, line frequency, diode drops and tried out the NCV function. Everything works accurately and as advertised. Couldn't ask for anything more considering the very reasonable cost.
