Feature

The display module shell adopts sandblasting oxidation technology, beautiful and elegant. Touch control buttons with high sensitivity and long service life.The measuring module can detect the current in both directions. No need to change the wiring mode during the charging and and discharging of the battery, and it's convenient for wiring.
The measuring module needs to be connected in series to the circuit under test, and send the measured data to the display module for display. The data between them can be transmitted via USB cable (1 meter long), it can also be wirelessly transmitted through the built-in wireless module. The wireless transmission distance is up to 10 meters.
Adding self-calibration function to solve the problem of zero drift in old products. After a long time of work, the current and capacity can still maintain a great accuracy. Press any key to switch to the full-function display mode. Under the full-function interface, you can set the required parameters, and you can also set a black display on white mode, and the display can be seen under sunlight.
After the measurement module is connected to the relay, it will have functions of over-voltage protection, over-current protection and under-voltage protection in the circuit.The display screen can be closed, press any key to wake up the display, more energy-efficient.
The data of amp hour, watt hour, and time can be cleared during the measurement without affecting the next measurement.Different communication addresses can be set in the wireless mode. Multiple machines can work at the same time without interference.

Description

This multi-function voltage and current meter can measure DC voltage, current, power, watt-hour, temperature, the real-time capacity of battery charging and and discharging, time of the battery charging and discharging, and other parameters in both directions. The wireless DC voltmeter is divided into two parts: measurement module and display module. The display module adopts 1.8-inch high-definition color LCD display, which is very suitable for monitoring the battery capacity of the electric vehicle and monitoring the working status of the DC circuit.
