Features: 1. Resistance test: Use the F button to select the resistance measurement mode. When the load is overload, the 'ol symbol is displayed on the LCD screen. 2. Lighting diode component test: Easily detect the built -in diodes, and can also test the product test on the board. It is light and convenient. 3. Automatic shutdown button battery life: Use 1 CR3032 button battery. After starting in 20 minutes, automatically shut down more power! 4. Capacity test: Select the capacitor measurement mode, and contact the capacitors on both sides of the capacitor in the circuit board. 5. Data keeping key: When pressing the function key, the instrument stops refresh the test data, and keeps the current test data. When pressing this key, return to the normal test status. 6.SMD Patch Test: A recognizable resistance/capacitance/diode and other components, accurate testing, electronic factories and electronic maintenance good helpers. 7. Handheld test sheet champion device, special gold -plated tweezer design, test accurately and gently, quickly judge the component.
