Airepair LCR-AR1Product Features
1. Compatible with SMD sockets, this device offers flexible support for various components. It allows for easy measurement of all types of surface-mount components without frequent socket changes, making testing more convenient and efficient.
2. Short-circuit test ports 1, 2, and 3, then press and hold the TEST button for 3 seconds to enter the self-calibration process. Regular calibration ensures that measurement data remains reliable at all times.
3. Supports NEC protocol infrared signal decoding, allowing you to read remote control codes and display waveforms—an essential feature for home appliance repair.
4. Switch to Auto mode, and the device automatically identifies component types. A short press of the TEST button starts the measurement, handling transistors, diodes, capacitors, inductors, and resistors with ease.
5. Press the button to manually switch to the desired measurement mode; the screen displays the corresponding icon in real time to meet specialized testing needs.
6. Suitable for product R&D, home appliance repair, educational experiments, scientific research testing, and other scenarios—a reliable tool for electronics engineers and hobbyists.Product Specifications
Model: LCR-AR1
Display: 1.9 inches
Battery Capacity: 300mAh
Charging Specifications: USB Type-C, 5V/1A
Dimensions: 62 x 90 x 32 mmProduct Description
The LCR-AR1 Transistor Tester is a high-precision, multifunctional electronic testing device designed specifically for electronic engineers, technicians, and electronics enthusiasts.
This device is designed to detect and analyze the performance and characteristics of semiconductor components such as transistors, diodes, triodes, and field-effect transistors (FETs). Equipped with a color screen, it supports multi-parameter measurement of various components, automatically identifies the type and pin configuration of the device under test, simplifies the operation process, and improves testing efficiency.Precautions
1. If a capacitor is measured without being discharged first, the device will discharge the capacitor upon insertion and locking, which may cause sparks. This feature is intended solely as a safeguard against forgetting to discharge the capacitor; for proper use, it is still recommended to manually discharge the capacitor before testing.
2. When not in use, the 123 locking interface remains in a conductive state; do not insert batteries directly.
3. If component parameters fall outside the test range, the results may indicate an incorrect component type.item list:

1. Portable Design: Features a 1.8-inch screen and a compact form factor. Includes a built-in battery monitoring function (0.1–4.5 V) and alerts users to recharge when the battery level drops below 3 V.
2. Self-Calibration Mechanism: To improve measurement accuracy, perform internal calibration by briefly touching the test probes together to trigger the “Please isolate probe” prompt.
3. Type-C Interface: Standard Type-C port with a built-in 300mAh battery. The indicator light turns green when fully charged; use a 5V/1A external power source for charging.
4. High-precision measurement ranges: Supports resistance measurement from 0.01 to 50 MΩ, capacitance from 25 pF to 100 μF, inductance from 0.01 mH to 20 H, Zener diode breakdown voltage from 0.01 to 4.5 V, and forward voltage drop of standard diodes from 0.01 to 30 V.
5. Multi-Function Component Identification and Measurement: Automatically detects and identifies various electronic components including NPN/PNP transistors, MOSFETs (NMOS/PMOS), IGBTs, JFETs, diodes, Zener diodes, thyristors (SCRs), resistors, capacitors, and inductors, and displays their key parameters.

Function Keys
Auto Power Off (Automatically shuts down after 30 seconds of inactivity)
Supports Chinese and English language switchingPrecautions
(1) After powering on, the device will automatically check the battery level and display it. When the battery voltage drops below 3.1 V, please recharge it promptly to prevent damage to the device;
(2) It is not recommended to use the device to measure battery voltage; the battery voltage must be below 4.5 V, otherwise the device may be damaged;
(3) If the parameters of the component being measured are outside the test range, the test results may indicate an incorrect component type;
(4) This product contains a lithium-ion battery. Do not expose it to fire to avoid danger; do not attempt to power on the device immediately after exposure, as this may damage internal components.
(5) During use, avoid subjecting the device to violent impacts, drops, or water exposure. If the device accidentally gets wet, allow it to dry completely before attempting to power it on; otherwise, internal components may be damaged.item list:
