10. Timing the maximum range: 0-999 hours 59 minutes 59 seconds accuracy: 1 second
11. Parameters that you can test: Battery voltage. Current battery capacity, battery discharge capacity, the amount of electric charge, the battery power, the time.
12. Communication function: Yes
13. Parameters adjustment function: Yes. Equipment for parameter adjustment: An electronic load, a constant current source. Voltage source must be set to 8.5 V
There are 3A, 2A, 1A and models for the current setting 0.3A.
Here is an example for 3A:
When you set the electronic charging model to 3A, the current will be adjusted step by step.
It will cost you about 10 seconds and you can see the result of the change process on the OLED screen.
When you see the 3A result shown on the OLED screen, the adjustment process is completed. You can close
Off the electronic charge and the parameters will be saved automatically.
14. Clear the data: Press the button until the parameters changed for next parameter sets. Release the button.
Then the following sets of parameters will start and they will start from scratch.
15. Over voltage or under voltage: Over voltage or under voltage, OLED screen displays a warning symbol and rapid beep beep sound emission.
16. turn on l mode: the oled display will show all parameters within 1 s when you turn on the power by Micro USB or Male wired USB plug. (It is to check if the OLED screen is good or not). Then you can see the parameters last used (capacitor and what set of parameters). You can also see current, current and voltage over voltage or under voltage. Please refer to the illustration below.
