1.Main interface: When not d, the voltage is zero, the internal resistance is infinite, and it exceeds the range;

2.Main interface: When measuring, display the voltage internal resistance and record the measured internal resistance value;

3. System menu

Setting method:

Power on/off: When powered on for the first time, it will automatically turn on. If no internal resistance or voltage is detected, it will automatically turn off according to the "Energy saving Settings" time in the system menu, with a default of 2 minutes; You can also press and hold the "R" key to manually shut down, and clithe "R" key to turn on the device while it is turned off.

Record internal resistance measurement value: After measuring the voltage and internal resistance value, cli"M" to record the measured internal resistance value

press "▼" for 3 seconds to reset the recorded internal resistance measurement value,

Enter the settings menu: press the "M" key for 6 seconds to enter the system menu, clithe "M" key to switch menu options, and cli"▲" or "▼" when exiting the system menu.

Voltage display fine-tuning: Clithe "▲" or "▼" on to calibrate the displayed voltage. Calibration only adjusts the displayed value and has no effect on the actual voltage.

Internal resistance display fine adjustment: Clithe "▲" or "▼" on to adjust the displayed internal resistance, which only adjusts the displayed value and has no effect on the actual resistance value.

Standby time adjustment: Clithe "▲" or "▼" on to adjust the standby time.

Time unit: minutes

Display backlight adjustment: Clithe "▲" or "▼" on to adjust the screen brightness

Restore factory settings: Clithe "▲" or "▼" on to restore the factory settings, and "restored" will be displayed after restoration
