Hello TEA fellows,
last Thursday I've received a brand new DER EE DE-5000 which I've ordered in Japan via ebay mid of December.
It is a nice meter but one thing what annoys me is the so-called "backlight". A dim blue light which doesn't make
any difference between turning it on or not.
It came with the tweezer and this box with the crocos. I did a little teardown before I've turned it on and here are some photos:
I have some precision capacitors (100nF, 0,5%; 10nF, 0,3%; 1nF +/-5pF; 1µF, 5%) and a precise 10kOhm resistor, which I've built in 2016. Here is the link to the thread with some details:

(order of the measurements: 1nF, 10nF, 100nF, 1µF, 10kOhm)
And for comparison reasons, I did some more measurements with various meters.
Let's start with the Agilent U1252B:
(order of the measurements: 1nF, 100nF, 1µF, 10kOhm)
Next is the Brymen BM869s:
(order of the measurements: 1nF, 100nF, 1µF, 10kOhm)
Now the famous EEVBlog 121GW:
(order of the measurements: 1nF, 100nF, 1µF, 10kOhm)
This meter (EEVBlog BM235) is what I'm using, when I'm repairing stuff. I like it's size and handling and the backlight is not as ridiculus as with the BM869s:
(order of the measurements: 100nF, 1µF, 10kOhm - forgot to do the measuring with the 1nF
)
And the last one is my Schätz-O-Mat, a tester for transistors, diodes, LCR, whatever comes between the three crocos. I'd run the calibration procedure first before I did the measurements.
(order of the measurements: 100nF, 1µF, 10kOhm - forgot to do the measuring with the 1nF
)
I'm quite impressed about those russian capacitors. They are amazingly precise and are doing a good job. I'm planning to assemble a testbox for checking test gear on hamfests and those capacitors will surely go into this box.
Hope you've enjoyed this little comparison.
Best regards,
Mounty
