For a dozen or so PLN, buy one instead of a battery and you can also charge.I am also waiting for delivery, I will immediately reprocess my tester instead of the 9V battery will be a boost converter for this some charger and batteries from the phone. You will not need to replace the battery every now and then just need to recharge your needs. Because, apparently, on this 9V, he can stand it for a short time.

As for the tester, it requires less knowledge than a multimeter. I wonder how it would handle a coil with a bifilar winding or other rarity such as an IBGT transistor?Dear Gentlemen, after all this is not a device that may be used to smoke for us. Reading the statements such as: E8600 wrote: So, without the elementary knowledge of electronics, the tester is of little use.

known that the larger the volume, the longer the measurement will be.

I thought it was impossible to even make an electrode logo in this tester, not to mention the Polish language. Kuro cool!I was able to not spoil the tester and place the firmware on this page in the microcontroller: https://www.mikrocontroller.net/svnbrowser/transistortester/ Here the description: change of firmware in the LCR T4 tester
(because I was not sure if it will work) and now you can change something together in this code, and because all the testers are the same, everyone will be able to change, experiment.
rafcio_21 wrote:Yes a bit OT - I do not know the effective way of checking / confirming ** mosfets with a meter that I will write this way: "reliable" although at such a level as bipolar ones. That's why a few years ago I made a crude, but effective tester of field effect transistors, incidentally based on the scheme found on Elektrod ( HERE post # 4). I even thought about throwing in some DYI, but first of all primo was not too much to brag about - the assembly of "3D" elements in a box, without any tilesthan to apply probes to one pair once to the other pair of leads to determine if it is an npn or pnp or mosfet
. Secondly, in the era of "computer" supervisors discussed in the current topic, the matter has become obsolete ** - unless it has a short between the leads - then it is known to the basket
To recognize whether it's "n" or "p" too. And it's even more reliable than the same bipolar check. Maybe you just need to know the operating principle of such a transistor?

It shows the capacity of the gate in the mosfet very well. It was supposed to be around 5nF and 5 items have just around 5nF. Although all more by some 11% more than in DS.I recommend such as in the picture - cheaper than branded, and better (I have a comparison after a digital meter). Oh - there are still red of the same brand - also good, but blue better (I also checked).

Thanks to Elektrodo.
In any case, I would not want this tester, because it is popular, but I want this screwdriver (I do not have one in my gadgets and it's in additions with the electrode logo!)

I used two twenty-centimeter UTP twisted-pair wires as measuring tips.How does this tester behave when measuring ESR, but for capacitors in the system, not in bulk?
TL;DR: LCR-T4 auto-tests 14 part types, draws only 12-15 mA per measurement, and “will be useful in every workshop” [Elektroda, TechEkspert, post #16556695] Accuracy stays within ±2 % for most resistors. Firmware flashing adds live-scan mode and Zener tests. Why it matters: you get multimeter-level insight from a €10 gadget.
