fat lot o' good being a member of this group did me!
swore an oath never to buy another nixie counter.
but decided to attend the fest over in york this morning and spotted this 5221a.
never would have touched it (honest!).....but had never seen one in a carry case before. (already have 2 each working 5221b's)
was about to put it back in its proper place when the guy snuck up behind me and whispered "5 bucks".
damit! i am only human after all.
had to wiggle the boards to get it counting. but now it won't stop.
only 5 digits and 1Mhz.
what is it goood for? aaaabsolutely nothin'!
but it sure is cute.
ps asta and i may both be sleeping in the garage if swmbo spots it.
What I like about the XJW01 is the fact that it can fully automatic or you operate manually. I find the auto mode is perfectly acceptable and the screen is illuminated and it displays 7 parameters about the item under test. You simply attach the kelvin clips to the part you want to test and it automatically detect if its a resistor, inductor or a capacitor and select the appropriate mode. The only think you need to do is select the frequency at which to test the capacitors at and thats a single button press that will scroll through the options of 100Hz, 1KHz or 7.8KHz which seems to fit in with most capacitor data sheets I've seen.
The Peak devices give a parameter at a time and you have to scroll through them to get to the one you want.
Of the 3 devices I have, I just did some tests on a known cap, resistor and an unknown inductor...
Transparent case Black case XJW01
10uF 10.32uF 10.23uF 9.74uF
1.3ohm ESR 0.84ohm ESR 1.39ohm ESR
0.6% V Loss 0.5 V Loss 0.79% V Loss
3.298K 3.261K 3.3K 3.296K
Unknown Inductor
Pulled from PCB .08mH .08mH .07mH
The XJW01 is the go to tester on the bench the other 2 are useful for given approx values in circuit or as portables and they also have the added advantage of testing diodes and transistors including MOSFETS and will correctly identify the pin outs and the hfe.
So in practise there is very little between the results they present but sheer speed of testing the XJW01 is the clear winner.
There is connection between the screen on the BNC and mains earth so they are floating and the leakage to ground is 1.2v and that maybe more RF induced then actual mains leakage as the case is plastic on mine but the newer ones are extruded alloy but are powered via a wall wart and / or batteries.
The Philips Lehrbriefe are only available second hand today AFAIK.
Abe Books has both parts as well, shipping from Germany. Seems pretty cheap. Hope that helps anyone looking for it.

Hot damn, you STOLE that!!! It looks showroom fresh! The one I got a few years ago looks like ten miles of bad road in comparison.
Sweet deal!

No CRO, Plasma DSO. 2Ch 40Ms/s 100MHz. Strange form factor like some early portable computers.

Okay... that's pretty awesome feedback actually. I see that the AL Shell version has external power; to me this is a plus, especially considering how many 3S/4S LiPos I have floating around.
But... I'm seeing the DE-5000 for $78.00 or $101 full bundle (TL-21 alligators & TL-22 Tweezers) on eBay right now... It's pretty highly regarded here on EEVBlog. Can you make a considered comparison between the DE-5000 and the XJW01?
[EDIT]
Hmmm... the spec sheet for the DE-5000 is pretty informative. 100Hz, 120Hz, 1KHz, 10KHz, 100KHz test frequencies. 20,000uF/2000 H capacity with all the usual test parameters, and AC Resistance at the above test frequencies. Spec sheet says the TL-21 alligators & TL-22 Tweezers are both 4-wire measurement connected at the clips/tweezers. Sort mode with multiple tolerance ranges, and optional serial IR out to PC. Accuracy 0.3% to 3.0% depending on range. All with a common 9V battery for power. That is pretty damned impressive.
Further investigation of that LCR-TC1 Color Component Tester reveal a LOT of functionality for a small price ($US22-26 shipped); the usual Mega328 graphic component ID, looks like LiPo battery power supply built-in (Micro-USB charging?), IR Detector/Decoder, with junction test voltage up to 4.5V so Darlington HFe should be pretty accurate, and zener regulating voltage up to 30V. Sonuvacrap! That is a genuine little gem right there, if the overall accuracy is as good as you suggest!
Hmmmm... it may be time for yet ANOTHER Mega328 tester in my arsenal.

Joking aside, PM me a snail mail address; I'll drop something in the post for you to tinker with. I'm currently sorting through a huge pile of just this sort of junk to archive or trash; I'm sure I have something appropriate. You need what, 300-500mA? IIRC, you said it also drives the LED panel, right?

I think that's the last of 'em.

What a shitty way to earn yourself a crust: by ripping people off. I hope Karma pops a cap in their arse... not as a HipHopism, I mean literally I hope they wind up with a large capacity electrolytic in their anal cavity when it gets hooked up backwards to the mains. Might take some arranging, but I hear Karma is very resourceful.
Shitty Ebay crooks are murder! They should get a jaggy nettle dragged across their foreskin!

Only been to London twice...actually not really. Heathrow to catch a connecting flight to Edinburgh and then return trip back across the pond.
Ah, decisions decisions.
Should I
- go out and get yet another Tek 2456, presuming it hasn't been sold, or
- stay in to try to claim reply 10000, and almost certainly miss
