Mastfuyi Portable Digital Multimeter 6000-Count LCD Display with Backlight Flashlight Handheld Voltmeter Voltage Meter Universal Meter Measuring AC/DC Voltage Resistance Frequency Continuity NCV Test Meter Features: Made of quality ABS material, compact size & light weight & wear resistance, portable e and carry. With the upgraded chip, fast measurement & high precision. In the automatic mode, it can automatically measure AC / DC voltage, resistance and on / off. Press the NCV key and place the top of the meter close to the conductor. If the meter detects AC voltage, the meter will stop. According to the detected signal strength, the screen signal will show corresponding information. At the same time, the buzzer sends out alarm sounds of different frequencies. Support diverse measurements and functions, including AC / DC voltage measurement, resistance measurement, frequency measurement, live line recognition, continuity detection, NCV induction detection, flashlight lighting, automatic shutdown and data retention. With low battery indicator, it can remind you to replace batteries in time in case turned off when in use due to lack of electricity. If there is no operation within 12 minutes, it will automatically shut down to save energy.
