DIY Multifunction High-precision clock inside and outside Car temperature Battery Panel Meter for DC 12v OOTDTY Description: Multi-functional electronic clock module, set for time, inside and outside temperature, as You can display a single item, or you can cycle through the items alternately and customize the item to be displayed. for Time chip using for Specifications: 1, working for DC 5.0 ~ 28V 2, frame size: 22 * 58 mm 3, Installation hole size: 19.5 * 56 mm 4, display 5.0 ~ 28V 5, temperature display -35 ~ 120 Two temperature sensors 0.3 meters +1.5 meters 6, power length: 28CM How to use: UP the key: Under normal display, pressing this for key will between the six display states of Time Date Temperature 1 Temperature 2 Voltage Alternating Cycle Display. Note: The display items and switching interval for time in alternate cycle display can be customized by "dd" and "dF" parameters respectively. See the following table Under the key: Under normal display press this for key to enter the setting of for time \ date \ year \ parameter. Press the for key, "points" began to press the button to adjust the value. After adjusting, press the for key again, "hour" starts flashing, press the for key to adjust the value. And then press the for key to enter the date adjustment [Note that the middle of the colon is not lit], "day" began to press the for key after the tune "month" began to tune and then press the for key "year" Flashes, press the for key to adjust the parameters into the extended set, see the following "code significance and role of the table" The significance of the code, please refer to the following 1.0.0u measurement error correction, a positive number increases, a negative number decreases. For example, the actual supply is 12.0V, but the table shows 11.9V, it is adjusted to 0.1u. 2.Ac Temperature error calibration parameters. Positive number increases, negative number decreases, the unit is degree, the adjustment is -5 ~ 5. For example, if you think the displayed temperature is 1 degree than the actual temperature, then set -1, so the electronic clock is automatically reduced by 1 degree and displayed. Note: If you do not have a standard thermometer for reference, it is recommended to keep this as 0) Temperature error calibration parameters. Positive number increases, negative number decreases, the unit is degree, the adjustment is -5 ~ 5. For example, if you think the displayed temperature is 1 degree than the actual temperature, set it to -1, so that the electronic clock is automatically subtracted by 1 degree and displayed again. Note: If you do not have a standard thermometer for reference, it is recommended to keep this as 0) 3.dd cycle shows the display item [dd: 0] for time + temperature 1 + temperature 2+ [Dd: 1] for time + temperature 1 + temperature 2 [Dd: 2] for time + temperature 1 + [Dd: 3] for time + 4.Df the for time interval in cycle display, the unit is second, the adjustment is 1 ~ 9. For example, dF: 3, the switching interval is about 3 seconds to the display item once.(Please do not set to "0") 5.LL Display brightness level, the adjustment is 1 ~ 3, LL: 1 is the darkest, LL: 3 is the brightest. 6.AL Auto brightness control 0 to turn off the automatic brightness control, 1 to turn on the automatic brightness control. When set to 1, the electronic clock will change the brightness to level 1 after 19:00 everyday and change this level to level 3 every day after 07:00 Note: After adjusting the option, press "Down" again to return to the normal display all parameters and for time settings can be saved.
