XJW01 Auto LCR meter review ($120 bench top LCR meter)
<< < (13/26) > >>
buildafriend:
I just purchased a new one of these XJW01 meters. It came in a pretty robust metal case and seems to have gotten cheaper. It has undergone "some" evolution but seems to display the same things on the screen as what I've seen online. I got it for $80 including shipping. I want to thank you all for sharing this information. This is not a normal approach for finding technical information on a product. It seems to be somewhat scattered about and being translated in many different languages. I was about to throw the manual up here via google translate for everyone but Wh1sper beat me to it. Thanks Wh1sper and the OP :D

Okay soo..  :popcorn: there's a menu button. If you hold it down It says:
LCR Set Options
Exit: X   Ver:5.5
There is no X button :palm: So restart it via the power switch and pretend I don't need to check that. Thanks for the options  :-//

I see my set of shielded probes, that's nice. Maybe a little bit long for testing in low pF ranges but still pretty nice. The BNC jacks are labelled as follows -
Lc Lp Hp Hc

Lc = Loading capacitor? Inductive Capacitive? Left Channel? Low?
Lp = Plate Load? Inductive Plate?
Hc = Henries passive? Hot? .. You get it. What the heck do these mean?
Hc = ?

I plug the black clip leads into the left, and red into the right. With no attention to polarity or what is signal or ground and then put a 10K R between the clip leads. It works. I swap some leads on one probe. It works. I get a reading near 10K.. Okay that looks correct

Then there's a whole range of other buttons. It seems like each button has a quick press function followed by a press and hold function.

Okay so here's a description of each button. As far as I can tell, the auto function does a lot. But sometimes I'm not getting all the info I want like what the impedance of what a given coil is.. How do I view ESR? What is this 2.7Mohm thing? Okay the buttons descriptions -

RNG / *image of gears* ( this button is blue )

Zero / *recycle logo-ish image with 2 arrows going in a circle* ( this button is red )

Hand / Aut ( this button is blue )

CLR / *recycle logo-ish image with 3 arrows going in a circle* ( all buttons from here down are green )

S *dot* P / ESR

QTY / +/- %

Freq / *picture of sine wave*

What do all of these buttons do????
Yansi:
You should probably dig more into how these things work. The lead length does not matter (in theory of course) - thats why they are four of them!  Two force ones (carrying current, that would be the two outer jacks noted as "c", and two voltage sense ones noted as "p". "c" might stand for current, not sure what "p" might be. L is just the Low voltage side where the I/V converter is and the H is  the high side where the source is.

Each probe has two BNCs. They are both connected to the same probe, making a kelvin point at the jaw.  It does not matter, where each BNC goes, as far as one probe has connected both L jacks and the other probe both H jacks.

Please do your homework a bit more thoroughly, before bitching about things the manufacturer is not responsible for.

Can't say much about the user interface though.
Specmaster:
Yes, the manual could be a lot clearer, but I have one and have found it to be incredibly accurate, although I can't vouch for the inductance ranges though.
Yansi:
That is the sole purpose of a proper 4-wire impedance bridge - to be accurate means of impedance measurement.  >:D

Even this cheap Chinese meter is miles ahead, of what a common two-wire measurement using your other (multi)meter can provide.

Inductance measurement should be "accurate enough" too. Not sure where the limits are of this Chinese one are either.

Bitching? There's no bitching here man  ;D

I'm just trying to learn this tool! Now at least I have some terms to look up. Thanks for the replies guys. Any more helpful information is invited.
