This multifunctional tool Features the function of multimeter, electrical test pen, temperature meter and flashlight. With large LCD screen for easy reading and comfortable grip for easy operation, it can be widely used in electrical testing, car repairing, industrial temperature measuring, etc. Features: 3 in 1 multifunction of multimeter, electrical tester and temperature meter. 2 measuring pens and a thermocouple are easy to install and use, allowing it to be widely used in electrical testing, car repairing, industrial temperature measuring, etc. True RMS digital clamp meter with 9999 counts, wide measuring range and high accuracy. It can test AC current, AC voltage, DC voltage, AC current, temperature, capacitance, resistance, continuity, diode, frequency and live wire. NVC induction: bring the NVC part close to the wire, and it will send out an audible and visual alarm when the AC voltage is detected. Zero/ live wire detection: use measuring pen to recognize zero line and live line safely and easily. Auto correction of wrong gear in capacitance measurement: if the non discharged capacitance is measurement in the capacitance gear, the instrument will automatically jump to the voltage gear to protect the instrument from being damaged. Large and clear LCD screen greatly enhances the reading experience and makes it easy to read, screen size 53x35mm. With LED flashlight to illuminate the measurement object without fear of dark environments, ensuring safe work. Powered by 2 AAA batteries (not included), with low voltage prompt. It will auto shutdown to save battery if no operation for some time. Ergonomic design makes it perfectly fit your palm for easy use. Compact and lightweight, portable to carry. Note: 1. Please read the user manual carefully before use. 2. Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
