Feature

The display header and measurement module can be used between the wireless transmission of data, reducing the tedious wiring, but also to avoid the loss caused by the error, the maximum distance of communication is 10 meters, you can also use the standard USB cable for wired communication , Due to the use of 485 communication, the length of the line can be extended to 1200 meters;
Bi-directional detection of current, for the detection of charge and discharge users can easily detect the two-way current, without changing the wiring.
Power-off memory function, the display header power can be saved before the power to save the settings and security hours, watts and time to facilitate observation and measurement, but the measurement module before the need to press the "OK" button To save the parameters;
Voltage, current, power, charge and discharge capacity, watts and time at the same time display, display a comprehensive and clear information.
With overcurrent, overvoltage, undervoltage, time limit protection (extended relay action time) and other functions.

Description

The number of hours, hours and time to clear the function, does not affect the next measurement.
You can set each individual address, and use a display to view multiple measurement board measurement parameters.
The use of multiple machines at the same time, you can set up a separate channel for each machine to avoid mutual interference.
With a screen lock, timer off, brightness adjustment and change the language display and other functions.
