12V Digital Multifunction Clock Thermometer Voltmeter Blue

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.
