1、Multiple Functions: This multimeter can be used for AC DC voltage and current testing, buzzer on and off, resistance, frequency, breakpoint detection, environmental temperature, neutral fire wire identification, etc. 2、NCV Detection: This digital multimeter has NCV non contact voltage detection function, which safely detects live wires without direct contact, ensuring safe and reliable measurement. 3、Quick Recognition: Quickly identify and measure AC voltage, without worrying about the wrong gear and burning the multimeter, with automatic range recognition, resistance maintenance and detection. 4、Value Screen Locking: This multimeter can quickly and accurately measure the voltage value of car batteries, with high accuracy. Press the H key to lock and keep the current measurement value on the screen. 5、Line On Off Detection: Connect the probe to both ends of the wire. If there is a beep, it indicates that the wire is connected, and if there is no beep, it indicates that the wire is disconnected. 6、Automatic Shutdown: After the multimeter is turned on and not used within 15 minutes, it will automatically turn off, making it suitable for professionals, electricians, or electrical enthusiasts to use.
