Features 1、LCD Display: The smart SMD tester adopts an LCD screen with high definition display, clear and intuitive, ensuring accurate and stable readings, suitable for electronic component testing applications 2、PC Housing: The shell of the test tweezers is made of PC material, which has strong toughness, wear resisting, and high security, making it suitable for various measurement environments Specification Item Type: Smart SMD Tester Resistive Value: Range: 300/3k/30k/300kΩ, Accuracy: ±(1%rdg+5dgt) Range: 3 MΩ/30MΩ, Accuracy: ±(2%rdg+5dgt) Capacitance: Range: 3nF/30nF/300nF/3uF/30uF/300uF, Accuracy: ±(3%rdg+5dgt) Range: 3mF/30mF, Accuracy: ±(5%rdg+5dgt) Diode: Open Circuit Voltage: 2.8V, Test Current: 1mA Battery: 1 x Button Cell (not included) Size: Approx. 4 x 17cm / 1.6 x 6.7in 1. Automatic Scanning After turning on, the screen displays SCAN and ---- symbol, indicating that the meter is in automatic scanning test mode. Simply measure the component being tested, and the meter will automatically determine resistive value, diode, or capacitance, displaying the measurement value on the screen. Note: When measuring components on a circuit board, be sure to power off and discharge the capacitor voltage. 2. Resistive Value Measurement ① In automatic scanning mode, measurement range: 0.1Ω-3.000 MΩ. ② In manual measurement mode selected by the FUNC key, the measurement range expands to 30MΩ, namely 0.1Ω-30.00MΩ. When overloaded, OL is displayed. Note: This tester does not have a beeping measurement function. When selecting the beeping symbol with the FUNC key, the function is for 300Ω resistive value measurement. 3. Capacitance Measurement ① In automatic scanning mode, measurement range: 0.3nF-300.0uF. ② When entering capacitance measurement mode with the FUNC key, the measurement range expands to 30.00mF, namely 0.1nF-30.00mF. Note: Before measurement, be sure to discharge the voltage on the capacitor to prevent electric shock or damage to the meter.
