Features: Intelligent multimeter with many functions: it can measure AC/DC current, AC/DC voltage, resistance, frequency, continuity, fire wire detection, etc. Dual flashlight design: two flashlights at the top for additional illumination of the work area in dimly lit or dark environments, are not afraid of darkness during operation and will turn off automatically after about 5 minutes. Non-contact NCV voltage detection: Place the NCV sensor closer to the measured cable, and the multimeter can detect whether the voltage is greater than the alternating current voltage of 90V. When the AC voltage is detected, the meter beep is turned on, and the induction intensity is displayed on the LCD analog strip. Operational safety: Built-in overload protection fuse, intelligent burn protection. They meet DC/AC 600 V CAT III surge standard and double insulation protection (Class II). Large LCD screen and easy control: Soft buttons are easy to operate, the instrument is used to display 6000 counts, LCD display, backlight display and clear reading. Automatic shutdown: The multimeter will turn off automatically after 15 minutes. Current detection alarm function, live wire measurement alarm. Compact and accurate: as small as a mobile phone, convenient to use and wear. Built-in with high-performance chip to ensure its accuracy. Silicone protective case: Protected by a soft silicone cover, you can use the meter in a variety of conditions without worrying about it falling or scratching your equipment.
