Features:
1. Use a single precision type electric constant current source and electronic switching circuit to realize accurate current control of battery charging and discharging.
2. Up to 1.6A charging current and 2.0A discharging current to adapt to the majority of battery testing, current can be adjusted over a wide range.
3. Battery voltage is designed as four-wire differential test, better precision (test point is the pad of battery box).
4. The second charging section is innovatively designed with a proportional capacity fast termination function, which can greatly save the overall time of dividing a battery (the traditional program generally needs to be charged to about 3.8V for a long time).
5. Support batch parameter modification (connecting synchronous signal line) interrupt signal mode without limiting the number of cascade.
6. Battery line with reverse protection, support for automatic start test, easy to use.

Key operation description:
"+" "-" button: the test is responsible for switching to view the display parameters, set the test parameters are responsible for changing the parameter items and values, in the standby state at the same time press and hold for one second to enter the parameter setting interface.
"OK" button: short press to start the test in standby, long press to force exit in the middle of the test (without recording the completed parameters) and start again to restart the test. Short press to exit the error display when "Er *" is displayed. Short press to switch setting items and parameters in the setting page, long press to exit and save the parameters modified by setting.
Display description: the digital tube displays the data, above the digital tube is the function-unit lamp, in which CHG1 (yellow) is lit on behalf of the first charging is being performed (flashing represents the end of charging wait countdown), DCHG (red) is lit on behalf of the discharge is being performed (flashing represents the end of discharging wait countdown), CHG2 (yellow) is lit on behalf of the second charging is being performed, COMP (blue) is lit on behalf of the The test has been completed. The second vertical column of unit lights represent the current charging or discharging current A, battery voltage V, A and V lit at the same time represents the countdown time in seconds, and the capacity of Ah, which use the second stage of the proportional capacity of the rapid charging function, the second stage of the charging process shows the capacity for the current has not been charged into the battery's capacity, and stop charging when the countdown reaches zero.

Parameter setting instructions:
Standby state at the same time press and hold the "+" "-" button for about 1 second to enter the setup parameter display page, enter through the "+" "-" button to switch to the parameter to be modified, short press "0K" button to enter the corresponding parameter modification, modify a good parameter can again short press "0K" button to enter the corresponding parameter modification, after modifying a good parameter can again short press "0K" button. "-" button to switch to the parameter to be modified, short press "0K" button to enter the corresponding parameter modification, after modifying a parameter can again short press "0K" button to return to the parameter selection interface or long press "0K" button to return to the parameter selection interface or long press "0K" button to return to the parameter selection interface. "0K" button to save and exit the setup, if more than one tester is connected with signal lines in sequence and in standby mode, the synchronized parameter will be sent at this time, and all the testers connected with back-end signals in series will be modified into the same working parameters at the same time.
The meaning and range of each parameter is shown in the chart:
Supplementary: When the capacity percentage of the second charging capacity termination is set to "EE", it means that it does not perform proportional capacity termination charging but ends after the battery is fully charged according to the voltage and current setting parameters.
