this is a New Multimeter since 16th Sep 202.

RM777 is an automatic range digital multimeter with 9999 words with a true effective value. The instrument is full-key operation with triple display.
Measure AC voltage and DC voltage
Measure AC and DC current
Measuring resistance/temperature
Test continuity and diode
Measuring capacitance/NCV
Measuring frequency and duty cycle
Anti-interference AC voltage detection

it is very easy and comfortable to Grip.
