Perfect device very very good

Review for FNIRSI LCR-P1 transistor tester. I used two methods to verify the accuracy of this tester. First, by comparing the readings against my multi-meter, and second, by testing known value parts and comparing the readings. First test was with an ancient Germanium transistor. The tester identified the lead pin out, the polarity as PNP, the Vbe (base to emitter voltage) and hFE (current gain). The hFE was close to what the multi-meter read. As another test tried rotating the transistor one half turn and reinserting into the socket and it still identified the leads correctly. Next, resistor function was checked. Again, the readings were very close to what my Multi-meter read. Then Capacitance function was checked. The tester will read value and ESR (Equivalent series resistance). The values matched the multi-meter with some exceptions. It read a 2000 Pf mica capacitor as 1nF (1000 pf) that is a 50% error. Yet the Multi-meter read the correct value. Next inductance was checked. It will show the value and DC resistance of the inductor. In this case I was only able to verify the DC resistance against the multi-meter. Also tested the zener diode function. The zener voltage shown was very close to the rated value of the part. Finally, used tester to read the codes of various infrared remote controls. It could not read all remotes, not sure why. This tester does have a few quirks. When you first press the test button to wake up the unit it will show "unknown/No component/Or damaged" just press the button again and the test will proceed normally. Also the value sometimes shows as only one significant digit (1 nf) not high accuracy. One more note and this is not mentioned in the manual when charging the battery, the LED indicator will change from red to green when the battery is fully charged. To sum up, this is a well designed tester which combines several devices into one unit. The instruction manual is clear and well written. The only drawback is there is no USB power module included, but if you are like me you already have several of these lying around.

Facilidad/Versatilidad de uso para los entusiastas a la electrónica

Nice tool works well, quality item nice finish and rechargeable, also flying in Leeds and little PCB thank you very much

This thing works great multi use great for checking all kinds of electrical components easy to understand. Easy to use.
