LC100-A LC-100A Digital LCD High Precision Inductance Capacitance L C Meter Accuracy 1%

I got this to measure inductance on copper tubing work coils used in a 1000 Watt ZVS heater circuit to anneal rifle cartridge brass. Getting the inductance right is critical to the circuit operating with efficiency and not over heating the components too much.Unlike cheaper options on another site (***y) this device actually works. With Amazon you can actually send back if it doesn't. It cost twice as much here, but hey it's still pretty cheap and it works and the other didn't. So it's worth it.I can't completely vouch for accuracy but it seems to be pretty good. Testing some open air coils appears to produce accurate measurements that reasonably match the values produced from formulas.Be sure to follow the reset procedure to zero it each time. I do not think it retains any zero when powered off. For inductance you short the leads and then hold the red zero button until it says "ok". (or some versions of firmware might say "saved"). For capacitance measurements you leave the leads open circuit and do the same.My coils I'm measuring are around .8 to 1.5 uH. It does seem to be sensitive to how the leads are oriented.I notice some drift as well. Initial measurement on one coil was 1.53uH. Leaving it connected for a while (15-20 min or so) it drifted down to 1.42uH. Short the leads & reset zero, then it measures 1.53uH again.So as long as you're diligent about the zero reset for every measurement, it seems to be pretty good.I also tested with a small value capacitor. Marked value was 0.1uF. Measured value was 101.5nF. Put it in Hi C mode and measured value was 0.09uF. Though I don't need it for that, seems like it's decently accurate on capacitance as well.

This meter makes it easy to get a good value on winding coils for ham radio. The accuracy is good enough that what you make will work. I have not tested it against a higher priced unit, but it works well enough for me.

This is a great accurate product, but I gave it one short of 5 stars because no instructions are supplied, which can lead to getting bad readings.Goggle for the instructions and you will find them on mpja.com.You can get bad readings if you do not zero the meter properly.YOU MUST ZERO BY HOLDING DOWN THE BUTTON FOR SEVERAL SECONDS UNTIL THE DISPLAY READS "DATA STORED".Only then will the meter read faultlessly.Having no instructions, I just momentarily pressed the zero button, thinking it was all good, but while a 0.1uF capacitor read correctly as 0.095uF, a 4.7uF capacitor read as 1.45uF. When I figured out you had to hold down the zero key for a while, I got great readings, and the 4.7uF read as 4.5uF.Cannot comment on the durability of this device as I have only had it a day, but I will be definitely keeping it as a valuable tool, now that I know how to use it properly.

This LC meter is actually better than they claim. It can measure very small values of capacitance and inductance beyond advertised numbers. It is also much simpler to use than the manual describes. The accuracy is very good. If you need a good LC meter, especially one that can measure very small values, this is hard to beat at 10 times the price. Highly recommended.

I need to measure inductance in the range of 10-50 microHenrys. I first got one of the popular 'Proster' LC meters. As an accuracy check I bought two 5% inductors, one at 16 uH and one at 27 uH. The readings from the Proster were; 16 read as 21.6, 27 read as 31.7. So inaccurate as to be useless for my purposes.So I got the LC100-A device hoping for more accurate readings. Much better results: 16 read as 16.36, 27 read as 25.49. So the Proster meter was a waste of money, since the LC100-A is about the same price and clearly works much better, at least on inductances (haven't tried the cap measurements yet). Note that this meter is supplied without a case or power supply, i.e. 'bare bones'. However is can be used as is, and can be powered from any USB charger. All in all I am very happy with this gadget. Don't forget to rezero often for best accuracy!

Disliked= No instructions, very finicky. I may spend more money for a larger device if it is more reliable. I had to wrap wire around the clip leads to get a reading. I think that the leads are part of an RF circuit, so their proximity to each other affects readings. Maybe the leads should be shielded?Liked= It sometimes works and I get pretty accurate reading on most marked inductors. It was cheap $$.

I have been using the L/C meter for a few days now and let me tell you, it is spot on! It is accurate and fast. Might be the best $28 dollars I have ever spent

I design and prototype RF devices, and I find this handy little thing quite useful. Surprising accuracy.
