User Guide:

Short press:

In the normal display state, short press the setting button to switch between the five display states of [for Time] → [Date] → [Temperature] → [Voltage] → [Alternate Cycle Display].

Long press:

In the normal display state, press and hold the setting button for more than 2 seconds, the for time/date/year/parameter setting will be entered. "Minute" starts to flash, short press the setting button to adjust the value. After adjusting, press and hold the setting button for more than 2 seconds. "Hour" starts to flash, short press the setting button to adjust the value. Then press and hold the setting button for more than 2 seconds to enter the date adjustment [note that the colon in the middle is not lit], the "day" starts to flash, after adjusting, press and hold the setting button for more than 2 seconds, "month" starts to flash, after adjustment Press and hold the setting button for more than 2 seconds. "Year" starts to flash. After adjusting, press and hold the setting button for more than 2 seconds to enter the extended parameter setting.

After entering the code function setting, it is also possible to press the setup button for more than 2 seconds to skip to the next parameter setting. Short-press the setup button to adjust the parameter value. Refer to the following table for the meaning of the code:

Ac: Temperature 1 error calibration parameter. A positive number represents an increase, a negative number represents a decrease, and the unit is degree. The adjustment range is -5~5. For example, if you think that the displayed temperature is 1 degree higher than the actual temperature, then set Ac:-1 so that the electronic clock is automatically displayed after subtracting 1 degree. (Note: If you do not have a standard thermometer for reference, it is recommended to keep this item as Ac: 0)

Dd: Display item during custom cycle display [dd: 0] for Time + temperature + voltage [dd: 1] for Time + voltage [dd: 2] for Time + temperature

dF: Switching interval when the custom cycle is displayed, the unit is second, the adjustment range is 1~9. For example dF: 3, just

The switching interval is about 3 seconds to switch display items.

LL: Displays the brightness level, the adjustment range is 1~5, LL: 1 is the darkest, and LL:5 is the brightest.

AL: Automatic brightness control switch, AL:0 is the automatic brightness control, AL:1 is the automatic brightness control. When set to AL:1, the electronic clock will change the brightness to level 1 after 19:00 PM every day. After 7:00 AM every day, the brightness will be changed to the luminance level in the LL option.

0.0u: The voltage measurement error is corrected. A positive number indicates an increase, and a negative number indicates a decrease. For example, the actual supply voltage is 12.0V, but the table shows 11.9V, then it is adjusted to 0.1u.
