Functions: Multi-function multimeter with wide test range: digital multimeter can measure AC or DC voltage, resistance, capacitance, frequency, diode, continuity, NCV live line. Intelligent functions: measuring diodes in the range of 3 V. when the resistance is less than 50Ω, the buzzer will turn on when measuring the resistance. The buzzer turns on when the voltage signal is recognized Lithium-ion battery: built-in 800mAh lithium-ion battery, convenient to use and charge. High precision display: 3,5 inch large EBTN LCD display greatly improves the reading experience, the value is very easy to read even in sunlight or in poor lighting. Reliable and practical: NCV measurement, automatic range of 9999 counts, intelligent multimeter with data retention function. Safety assurance: with full measuring range overload protection, double insulation, safety level KAT.II 600 V and KAT.III 300 V. Digital Pocket Handheld Multimeter: Compact, portable size designed with durable sleeve and storage case to protect against shocks, friction and impacts.
