XJW01 Auto LCR meter review ($120 bench top LCR meter)
<< < (19/26) > >>
nctnico:
The VC8145 DMMs I have are spot on down to the nf range using long wires.
Specmaster:
As far as I know, mine are also pretty much spot when it comes to measuring the capacitance, but what's more important to me is the ESR values.
SteveSi:
Video here on how to use and what buttons do and what screen means, etc.

Hello,

I know that this thread is a bit old but I wanted to chime in and give you an opinion on the XJW01.
I own several LCR bridges and meters. I have the following GR units: 1650A, 1650B, 1656. I had a 1657 DigiBridge but sold it before I owned the XJW01. I have a couple of HP4260A's that I have restored and A HP4262A with the comparator option that has recently been calibrated as well as a Wayne-Kerr 4250 which is dead on and has become my favorite DigiBridge. The 4250 does 120Hz, 1KHz, 10KHz and 100KHz. The W-K is the one I use when I want the best precision and the only bench unit that has 100KHz.

I bought the XJW01 as it was very inexpensive and interesting and small. Once I got it I tore it apart and found much to my surprise that it was very well built and the soldering and parts placement was as good as any PCB assemblies I have seen as I have spent the last 40 years designing electronics for a living.

So I put the unit back together and proceeded to compare it against my W-K 4250 using the calibration resistors supplied with the XJW01. Attached is a spreadsheet that shows the results of that test.

I did also do some comparisons on various inductors and capacitors and found similar agreement between the two devices, although I did not take the time to record this I found that for all practical purposes the performance within the same selection of frequency ranges was virtually identical. I found that the indication at 7.8KHz to be virtually the same as the indication at 10KHz on my W-K. I do wish that it had 100KHz but the lack of that range does not take away from the performance or utility of the device. Maybe when I have the chance and the time I will add the capacitor and inductor test results to the spread sheet.

In short the XJW01 is a very good buy for the money. The only thing I would like to do is to find a source for the empty case that the XJW01 is built in to build a battery pack that would fit on the rear of the case. So far I have not been able to find one. If anyone knows of a source please let me know.

One further comment there is a fellow on the internet that has an instructional video on the XJW01 and he offers an English manual for 3 USD. I highly recommend that you purchase that as it explains in detail the button functions and goes through the calibration procedure (I did not alter the as received calibration in any of my testing but it is good to know that I have the correct procedure to do this if I needed to do so).

There are also extensive Chinese archives one can find on the web on the various designs of this LCR meter including code and PCB layouts but I have not been able to find this information on the latest version. If anyone finds it I would like to have this information.

All in all the XJW01 is one of the best Chinese products I have come across, definitely worth the cost of less than a meal for 6 at McDonalds!

Specmaster:
Which model of the XJW01 do you have, is the one as shown in my photo further up the page or is it the silver one that has a flat format? I'm glad that you seem to concur with me that it is a very worthwhile piece of kit yet so many here seem to dismiss it entirely out of hand, instead favouring the XE5000 which costs loads more but does have the higher test frequency. For my intended purposes, the frequencies it has are more than adequate as I'm more interested in the testing of electrolytics and tants on power rails as in my experience these are the ones that cause the most problems and those are not used at higher frequencies, which is where ceramics etc take over and as such are relatively inexpensive to actually substitute to see performance increases as a result.
