DIY Multifunction High-precision Clock Inside And Outside Car Temperature Battery Voltage Monitor DC 12V Dropsh

Multi-functional electronic clock module, set time, inside and outside temperature, voltage as one. You can display a single item, or you can cycle through the it alternately and customize the item to be displayed. Time ch using Epson's RX8025T ch, this ch is a temperature compensated clock ch, time accurate. Standard 0.3 m +1.5 m module with two waterproof probes, temperature range -35 ~ 120 degrees. With brightne adjustment, 3 brightne adjustable. And automatic brightne function, can be dark at night, brighten during the day. Specifications: 1, working voltage: DC 5.0 ~ 28V 2, frame size: 22 * 58 mm 3, Installation hole size: 19.5 * 56 mm 4, Voltage display range: 5.0 ~ 28V 5, temperature display range: -35 ~ 120 °  (Two temperature rs ,0.3 meters +1.5 meters) 6, power lead length: 28CM How to use: UP the key: Under normal display, preing this key will switch between the six display states of 【Time】 → 【Date】 → 【Temperature 1】 → 【Temperature 2】 → 【Voltage】 → 【Alternating Cycle Display】. (Note: The display it and switching interval time in alternate cycle display mode can be customized by "dd" and "dF" respectively. See the following table Under the key: Under normal display status, pre this key to enter the setting of time \ date \ year \ parameter. Pre the key, "points" began to f, pre the on to adjust the value. After adjusting, pre the key again, "hour" starts fing, pre the key to adjust the value. And then pre the key to enter the date adjustment [Note that the middle of the colon is not lit], "day" began to f, pre the key after the tune "month" began to f, tune and then pre the key "year" start Fes, pre the key to adjust the 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 Voltage measurement error correction, a positive number increases, a negative number decreases. For example, the actual supply voltage is 12.0V, but the table shows 11.9V, it is adjusted to 0.1u. 2.Ac Temperature ① error calibration . Positive number increases, negative number decreases, the unit is degree, the adjustment range is -5 ~ 5. For example, if you think the displayed temperature is 1 degree higher than the actual temperature, then set Ac: -1, so the electronic clock is automatically reduced by 1 degree and displayed. (Note: If you do not have a standard for reference, it is recommended to keep this as Ac: 0) Temperature ② error calibration . Positive number increases, negative number decreases, the unit is degree, the adjustment range is -5 ~ 5. For example, if you think the displayed temperature is 1 degree higher than the actual temperature, set it to AC: -1, so that the electronic clock is automatically subtracted by 1 degree and displayed again. (Note: If you do not have a standard for reference, it is recommended to keep this as AC: 0) 3.dd Custom cycle shows the display item [dd: 0] time + temperature 1 + temperature 2+ voltage [Dd: 1] time + temperature 1 + temperature 2 [Dd: 2] time + temperature 1 + voltage [Dd: 3] time + voltage 4.Df Switch the time interval in custom cycle display, the unit is second, the adjustment range is 1 ~ 9. For example, dF: 3, the switching interval is about 3 seconds to switch the display item once.(Please do not set to "0") 5.LL Display brightne level, the adjustment range is 1 ~ 3, LL: 1 is the darkest, LL: 3 is the brightest. 6.AL Auto brightne control switch, AL: 0 to turn off the automatic brightne control, AL: 1 to turn on the automatic brightne control. When set to AL: 1, the electronic clock will change the brightne to level 1 after 19:00 everyday and change this level to level 3 every day after 07:00 am. note: After adjusting the AL option, pre "Down" again to return to the normal display state, all and time settings can be saved. Package include: 1pc DIY Multifunction Clock Temperature Voltage Monitor Panel Meter
