3-in-1 FunctionMultifunctional electrical tool acts simultaneously as a multimeter, non-contact voltage tester and phase sequence meter. Intelligent technology allows this multimeter to automatically identify the tested parameters and choose the required range. Ultra-Thin DesignLightweight design, easy to carry and operate with one hand, the switching function is quick and convenient. With LCD display with readable and clear numbers. Multifunctional MultimeterIntelligent recognition, auto range, TRMS 6000 counts, frequency, temperature, voltage, frequency, resistance, capacitance, diode, continuity, fire line identification tester Non-Contact Voltage TestDual adjustable range 12V-1000V / 48V-1000V (default). Distinguish between live wire and null wire by different frequency alarm sound. Non-Contact Phase Sequence DetectionIt can help you measure 380V three-phase electricity, judge the continuity of three-phase power supply. It can be widely used in schools, research institutes, factories, enterprises and other social fields. Features With built-in flashlight, it ensures clearer data reading. The pencil type has a lightweight design, easy to carry. It can be widely used in schools, research institutes, factories, enterprises, etc. Package Contents: 1 Multimeter 1 1.5V AAA Battery (Included) 1 Test Cable
