## Description

FNIRSI LCR-P1 Transistor TesterFNIRSI LCR-P1 transistor tester can be used for the measurement and analysis of NPN, PNP, triode, MOS, field effect transistor (FET), diode, Zener diode, capacitor, resistor, inductor, battery, etc.FNIRSI LCR-P1 transistor detector supports the analysis of NEC infrared protocol code, so it can be used for the debugging and maintenance of remote control equipment.1.44 inch full -color screen, clearly visible, 300 mah battery, Type-c interface for charging and data transmission, firmware upgrade.The capacitance resistance esr tester automatically identifies undischarged capacitors and automatically discharges them at the moment of insertion and locking, effectively avoiding accidental burning.

Review: Transistor FET tester - Nice tool works well, quality item nice finish and rechargeable, also flying in Leeds and little PCB thank you very much
Review: Great gadget, especially if you're a newbie to the electronics world like me?. - As someone who's still learning everyday, this is a very useful little gadget. I wouldn't say I'm anything close to competent but I have managed to fix a couple of graphics cards and another board. This has been very useful as I've had to take components of other broken things. But not knowing what the capacitors and the resistors at the 0402 size are due to their very tiny size. This has been immensely useful. Now that said, it does have a lot of issues picking up 0402 resistors. You have to try multiple times with a few different things such as mosfets Dr. It can take a few tries to get the right reading. But even if all it did was tell me the capacitors that pays for itself so 5/5.

### ⭐⭐⭐⭐⭐ Transistor FET tester

### ⭐⭐⭐⭐ The FNIRSI LCR-P1 is a very nice tester, but has a few niggles
*by Y***A on 30 March 2026*

The good thing is that the FNIRSI LCR-P1 is easy to use, for classic componects, transistors, diodes, capacitors etc, you connect them to the ZIF Socket, if you need to test SMD components, the ZIF Socket lifts out and the SMD Component tester fits in it's place. When testing this device, It has given values close to that of other testers, so it is fairly accurate, so I'm confident to use this for component testing components from now on. A nice electronic component tester for the price, but it does have it's niggles. I would have seen a better, clearer manual, especially for the beginners in electronics, the x3 test hooks are a bit flimsy, I would have like to have seen a littler better quality and maybe fitted with a 1x3 Pin dupont connector instead of 1x1Pin dupont connectors and having to insert them indivudually in to the device. The latest firmware v1.0.9 was installed, but it's not properly explained in the manual how to update the device, there are some youtube videos that will help you update the firmware. I thought I would check to see if the software worked. Initially it wouldn't work at all as it couldn't find an actual com port, to solve this I did the following to create a virtual COM port in Windows 11. In the Settings, Go to Bluetooth & Devices >then Devices > More Bluetooth Settings > COM Ports and add an incoming port to force the software to detect a connection. If after the firmware update, the screen is blank, open the FNIRSI LCR-P1 and disconnect the battery, the reconnect the battery, this should force a hard reboot. Yashima
