Features:
1. Compact construction enables comfortable one-handed testing, making frequent use effortless and helping prevent fatigue during extended tasks.
2. Equipped with four gear options, this tester streamlines diagnostics by removing the need for swapping additional components when switching between test modes.
3. Includes an indicator light on the test board: a flashing component light means the optocoupler under test operates as expected for straightforward confirmation.
4. Integrated charging automatically pauses once complete, thanks to the internal protection board, ensuring safe and maintained battery performance without a charging indicator light.
5. Features a built-in battery and a dual-use type-c interface, allowing convenient recharging and extended operation time with low power usage, no external power supply required.
6. Designed for broad application, suitable for analyzing a variety of electronic components including 4-pin and 6-pin optocouplers, triodes, 431 elements, IGBT power transistors, MOS transistors, thyristor modules, and capable of generating pulse square wave signals for versatile testing scenarios.
