Great little LCR meter
By S. Marum
You might be surprised at how non-ideal some of the electronic components you use really are. An ordinary digital voltmeter will tell you that your aluminum electrolytic is 4.7 uF, but the Extech 380193 will also tell you it has 2 ohms of series resistance -- a killer in the high current pulse generator I am designing. I got some pricey ceramic capacitors and found they have only 0.05 ohms resistance. Ahhh ... so that's why they cost 20x as much. How about that 0.05 ohm resistor used to sample current flow? Try measuring that with your standard DVM -- mine won't go below 0.3 ohms if I short the probes together. Plugging the resistor into the Extech shows it to be 0.047 ohms. Yes, this meter seems expensive at first glance, but try finding another LCR meter for anywhere near the price -- many cost 3 or 4 times as much. No, it's not perfect. Measurement frequencies are 120 Hz and 1000 Hz, a higher option would be nice. The keyboard is one of those rubber ones; sometimes I have to push pretty hard before the key registers. Still, if you need the component data an LCR meter will provide, the Extech 380193 is a pretty good deal.

Nice meter
By Cliff Harris
The quality of this meter is very good and the controls and display are easy to understand.This meter cannot measure DC resistance. Extech technical support advised me to get their LCR200, which does measure DCR, though it's not obvious from the description on Amazon or their own web site. It does spell it out in the user's manual, which is available for download on the Extech web site.

Good, full featured LCR Meter
By Brian Broggie
It's a very versatile LCR tester. I have used it to test very low-value inductors (1 uH) and it performs very well. For the engineers out there, it has several features that make this much more that a simple "go-no go" tester. For the price, you get a real fine piece of test equipment.
