User Instructions:

1. Setting the mode:

• AUTO: Discharge (to preset value) -> Charge to full. The battery Is discharged (@ ~1.7A untile the preset discharge voltage is reached then Charged @ ~1A until full.
• DSG (discharge mode): When the battery is fully charged, it uses a current of about 1A to discharge 1681mAh, which takes 118 minutes and 55 seconds;
• CHG (Charging Mode): The capacity and energy are not measured during charging, only the time is recorded, which takes 164 minutes and 51 seconds.

2. Method of use:

1. Install the power supply 18650 battery and the 18650 battery to be tested;
2. Use the Type-C data cable to connect the Type-C power supply port to the 5V power supply. The external power supply is used to charge the battery in the CHG state. If you only need to discharge the DSG, you can leave it unconnected;
3. Select the mode, the default is AUTO automatic mode;
4. Click the Start button to start the program;
5. Wait for the process to end and the status indication to stop;
6. About power-off storage: This product has no power-off storage function. Shutting down, restarting, and switching the working mode can cause the accumulated data to be cleared.

3. Language switching (if you find display in Chinese, then please follow these steps)

1. Shutdown
2. Press and hold the "菜单" key to start the machine, release the key after the screen lights up, and wait 10 seconds after starting the machine to shut down
