12V Digital Multifunction Clock Thermometer Voltmeter Red 40mm

12V Digital Multifunction Clock Thermometer Voltmeter Red

Specifications:

    This module has three functions on itself, clock, thermometer, voltmeter.
    There are four display modules: time only, temperature only, voltage only, time and temperature and
    voltage display in turns.
    It has temperature hand calib function, setting arrange is -5~5℃
    It has backup battery, so it will goes on counting when the power off.
    Small size: 40.0mm*13mm*13mm

Parameter:

    Input voltage is 5-15V, notice if you want to use the voltmeter function the input voltage should be
    Higher than 6V
    The voltmeter range is 6-15V, Deviation is±0.1V
    Temperature range is -9℃～60℃

Function and use:

First, adjust the time, date, year, voltage error, temperature error term is defined cycle, alternating intervals
Under non-setting state, press the left button of adjustment time (note in the middle of the colon is bright),

    At this time "minute" starts flashing, increase press right, adjust the range 00 to 59. After a good tune, "minute",
    Press the left button, then the "hour" starts flashing, increase press right, adjust the range 00 to 23.
    tuned "hour", then press the left into the adjustment date (note in the middle of the colon is off), then "day" starts flashing, press right to increase adjustment range 1-31.
    tuned "day", then press the left button, then the "month" starts flashing, press right to increase adjustment range 1-12.
    After adjusting the date, then the left, then "year" starts flashing, increase press right, adjust the range 2012-2049.
    adjust the "year", then press the left button, go to show the error voltage calibration function [x.xU], the unit is 0.1V, a positive number indicates an increase, a negative number indicates decrease.
    Then press the left button, enter the temperature error calibration settings [Ac: xx], xx on behalf of the correction value, increased by right, a positive number indicates an increase, a negative number indicates decrease in degrees.
    Press the left, into the cycle defined function dd option status display items, press the right to change the value: (dd: 0) time + temperature + voltage, (dd: 1) time + voltage, (dd: 2 ) time + temperature, (dd: 3) Temperature + voltage. Press the left button, the display alternately into circulation interval dF option, press right to change the value, the greater the value the longer the interval.
    Finally press the left button to save all settings value and return to normal display.
