Feature: 1. MULTIFUNCTIONAL: Digital multimeter can be used to measure AC, DC current, AC, DC voltage, resistance, frequency, duty cycle, capacitance, continuity, diode, temperature, live, neutral wire. In addition, there are multi function testers, such as in circuit testing and ammeter, which are necessary for all industrial and household electrical and electronic tools. 2. AUTOMATIC MEASUREMENT: The multimeter defaults to intelligent mode, and the voltmeter can automatically test. Automatically identify measurement content and select the best resolution range. 3. EASY READING: 9999 counter voltmeter, equipped with large LCD color display and flashlight, can easily read even in bright or dim places. In addition, the voltage tester can also display analog bars, real time temperature, low battery prompts, and fuse damage prompts. 4. PORTABLE: Multimeter is compact and portable. Perfect palm size, only slightly smaller than a phone. The ammeter is charged with a 5V charger (such as a mobile phone charger). If there is no test action, the LCD screen will automatically enter a sleep state. 5. FINE WORKMANSHIP: The fuse has anti burn and overload protection functions, making it safer and more reliable; The high impact resistant ABS and rubber, which conforms to a compact ergonomic design and adds additional drop protection. 6. IDEAL GIFT: A great surprise for any DIY enthusiast, and the smart mode makes it easy for the elderly to use!
