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. ## Features - Transistor Capacitor Tester: FNIRSI LCR-P1 transistor tester can be used for the measurement and analysis of patch component, NPN, PNP, triode, MOS, field effect transistor (FET), diode, Zener diode, capacitor, resistor, inductor, battery, etc - Friendly Design: The design of the replaceable patch seat enables measurement of both tiny precision components and high-power devices. 1.44 inch full-color screen, 300 mah battery, Type-c interface for charging and data transmission, firmware upgrade - Anti-burn protection mechanism: The capacitance resistance esr tester automatically identifies undischarged capacitors and automatically discharges them at the moment of insertion and locking, effectively avoiding accidental burning - NEC Infrared Waveform: 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, and provides users with comprehensive detection and analysis - Intelligent automatic identification: Capacer tester intelligent automatic detection of component pins definition and parameters, and can quickly identify its models and specifications, thereby greatly improving the efficiency of work ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DDBPWYP8 | | Best Sellers Rank | 52,078 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 24 in Capacitance & Resistance Meters | | Brand | FNIRSI | | Colour | Black | | Compatible Devices | Electronic devices with components like NPN, PNP, triode, MOS, FET, diode, Zener diode, capacitor, resistor, inductor, battery, and devices using NEC infrared protocol | | Customer Reviews | 4.3 out of 5 stars 782 Reviews | | Included Components | LCR-P1 *1; Patch test board *1; Test hook *3; Data line *1; Manual *1; Box *1 | | Item Dimensions | 8.1 x 6.5 x 2.5 centimetres | | Item Weight | 77 g | | Item dimensions L x W x H | 8.1 x 6.5 x 2.5 centimetres | | Item weight | 77 g | | Manufacturer | FNIRSI | | Manufacturer Part Number | LCR-P1 | | Measurement Type | LCR Meter | | Model Number | LCR-P1 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | CE | | Style | Transistor Tester | | Style Name | Transistor Tester | | Upper Temperature Rating | 40 Degrees Celsius | ## Product Details - **Brand:** FNIRSI - **Colour:** Black - **Item weight:** 0.17 Pounds - **Power source:** Battery Powered - **Style:** Transistor Tester ## Images ![FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter - Image 1](https://m.media-amazon.com/images/I/71vBeoBwVCL.jpg) ![FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter - Image 2](https://m.media-amazon.com/images/I/81dfU8x7cjL.jpg) ![FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter - Image 3](https://m.media-amazon.com/images/I/81xDqaoTXYL.jpg) ![FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter - Image 4](https://m.media-amazon.com/images/I/81WVKws6OCL.jpg) ![FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter - Image 5](https://m.media-amazon.com/images/I/81QvStnZ9dL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Transistor FET tester *by D***N on 22 November 2025* Nice tool works well, quality item nice finish and rechargeable, also flying in Leeds and little PCB thank you very much ### ⭐⭐⭐⭐⭐ Great gadget, especially if you're a newbie to the electronics world like me?. *by A***N on 25 August 2025* As someone who's still learning everyday, this is a very useful little gadget.

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.
