Diy Multifunctional Clock Car Temperature Battery Monitor Voltmeter

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 items alternately and customize the item to be displayed. Time chip using RX8025T chip, this chip is a temperature compensated clock chip, time accurate. Standard 0.3 meter +1.5 meter module with two waterproof probes, 3 brightness adjustable. and automatic brightness function, can be dark at night, brighten during the day.Specifications: 1. working voltage: DC 5.0 ~ 28V; 2. frame size: 22 x 58 mm; 3. Installation hole size: 19.5 x 56 mm; 4. Voltage display range: 5.0 ~ 28V; 5. temperature display range: -35 ~ 120 (Two temperature sensors, 0.3 meters +1.5 meters); 6. power lead length: 28CMHow to use: UP the key: Under normal display, pressing this key will switch between the six display states of [Time] [Date] [Temperature 1] [Temperature 2] [Voltage] [Alternating Cycle Display]. (Note: The display items and switching interval time in alternate cycle display mode can be customized by dd and dF parameters respectively. See the following tableUnder the key: Under normal display status, press this key to enter the setting of time / date / year / parameter. Press the key, points began to flash, press the button to adjust the value. After adjusting, press the key again, hour starts flashing, press the key to adjust the value.And then press the key to enter the date adjustment [Note that the middle of the colon is not lit], day began to flash, press the key after the tune month began to flash, tune and then press the key year start Flashes, press the key to adjust the parameters into the extended set, see the following code significance and role of the tableThe significance of the code, please refer to the following1. 0.0uVoltage 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. AcTemperature 1. error calibration parameters. 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 thermometer for reference, it is recommended to keep this as Ac: 0)Temperature 2. error calibration parameters. 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 thermometer for reference, it is recommended to keep this as AC: 0)Colour: black (blue light version)Material: plasticPackage Contents:1 x Three in one car clock(Digital display blue light)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
