Wide Applications SURLABA digital multimeter with high precision can accurately measure AC DC voltage (DC 600mV-750V; AC 6V-1000V), AC DC Current (600A 1000A); resistance (600 60M ), capacitance (6nF 60mF), frequency (9.999Hz 9.999MHz), temperature (-20 -1000 ), continuity, test diodes, duty cycle and batteries. This intelligent and advanced clamp multimeter can diagnose automotive, industrial and household electrical issue.

Fast and Slow Measurement The sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 0.125s time for general environmental measurement. The slow response rate uses a 1s time constant, which is used for environmental measurements with relatively large changes in noise levels.

Multi Function Clamp Meter Measure the DC voltage of 400mV-600V; AC voltage 4V 600V; DC current 400uA 4000uA and AC current 400uA-400A; Resistance 400 - 40M ;Non contact voltage(NCV) detection, diode, continuity buzzer test are also provided.

PROTECT THE BATTERIES Set parameters to realize multiple protection such as over voltage protection, under voltage protection, over current protection, over power protection, over temperature protection, and time limited protection to prevent damage to the electrical equipment. The shunt and screw are made of brass material, which has good conductivity, low heat generation and low power consumption.
