 instructions for use:

1 adjust the time, date, year, voltage error, temperature error cycle display item definition, alternate display interval

in the non-set state, press the left button to enter the time adjustment (note that the colon in the middle is on). At this time, the "minute" starts to flash, press the right button to increase, and the adjustment range is 00~59. After the "minute" is adjusted, press the left button again, and the "hour" starts to flash, press the right button to increase, and the adjustment range is 00~23.

After adjusting the date, press the left key again. At this time, "Year" starts flashing. Press the right key to increase and adjust the range to 2012-2049. After adjusting the "year", press the left key again to enter the error calibration function [x.xU] of the display voltage, the unit is 0.1V, positive number means increase, negative number means decrease. Then press the left key again to enter the temperature error calibration setting [Ac:xx],xx represents the correction value, press the right key to increase, positive number indicates increase, negative number indicates decrease, and the unit is degree. Press the left key again to enter the definition function dd option of the display item in the cycle display state, and press the right key to change the value: (dd:0) time temperature voltage,(dd:1) time temperature,(dd:3) time voltage. Press the left key again to enter the cycle to display the option of alternating interval time dF. Press the right key to change the value. The larger the value, the longer the interval. Press the left button again to enter the [LL:xx] brightness setting, LL:1 is dark, LL:3 is bright. Press the left key again to enter the [AL:x] automatic brightness function setting, AL:0 is closed, AL:1 is opened. When set to AL:1, it will automatically become level 1 brightness after 19 o'clock every day and level 3 brightness after 7 o'clock in the morning. Yes, press the left key again to save all the set values and return to the normal display state.
