Feature: 1. DIGITAL MULTIMETER: Accurately measure AC/DC voltage, AC/DC current, frequency, resistance, capacitance and diodes. This multimeter is a very useful tool for solving industrial and household electrical problems. Ideal for household sockets, fuses, batteries (including vehicles), automotive circuit troubleshooting, charging systems, electronic testing, and more. 2. EASY TO USE: This instrument is a handheld digital multimeter with true RMS value. It has a large screen 60000 counts LCD digital display, and It has a backlight (automatically adjusts the brightness when turned on) and lighting, making it easy for users to read. 3. NCV TEST: Rotate the rotary switch to the NCV position and place the top of the meter close to the conductor. If the meter detects the AC voltage meter, light the corresponding signal strength indicator according to the detected signal strength (low-yellow, high-red), and the buzzer will send out different frequency alarms. 4. AUTO POWER OFF: After about 15 minutes after power on, if there is no operating instrument, it will give audible voice prompts, will automatically cut off the power, enter the hibernation mode, in the automatic shutdown mode, any key can be restarted. 5. ADDITIONAL TIP: This multimeter is designed to safely and accurately solve a variety of automotive and home electrical problems. If you want to make some home or business improvements, it's a suitable tool for both DIYers and hobbyists.
