Mechanic V90E Voice Broadcast Digital Multimeter

This series of meters is a high-reliability digital multimeter with stable performance and battery driven.
The meter use a 26mm high LCD display with clear readings, backlight display and overload protection functions make it more convenient to use.
This series of meters can measure the effective value and average value of DC voltage and AC
voltage, DC current and AC current, resistance, capacitance, transistor, frequency, temperature, diode/on-off automatic identification test, intelligent voice reporting, high-voltage diode Output
measurement. It provides 1V higher voltage than the traditional diode measurement, which makes it easier for maintenance personnel to measure a variety of LED, and has been awarded the "Excellent Chinese Electronic Products"
