Specificatii
Atentie!!! Functia de Voltmetru e posibil sa afiseze informatii eronate la tensiuni mai mari de 9 - 10V
Product Feature:
-
Based on the single chip microcomputer, ultra-small ultra-thin designLong:40 mm wide:13 mm high:17 mm
-
Support Wide working voltage, can work at 5 v ~ 18 v, and with a voltmeter function, measurable input the size of the voltage.
-
A total of 4 kinds of display mode,(1) only show time(2) only show the date (3) only show the temperature (4) only show voltage (5) time, temperature alternating display
-
With the function of temperature display, display area - 20 ~ 59 ,Minimum resolution of 1 degree.With the temperature error correction ,Setting function, set the range - 5 ~ 5 .
-
With the function of 24 hours of timing error correction Settings
-
Using DS1302 chip timing, bring their own backup CR927 battery, When power lost, time to go on.

V.Related Questions
Why sometimes voltage measurement, the
measured value is wrong?
This is because the test voltage, the input voltage must be greater
than or equal to 7 v
Why when you measure the voltage and temperature change in value is
slow?
This is because the measured voltage and temperature is 0.5 S read
once, then displayed
Why is the measuring temperature, numerical value is not very
stable?
This is because the resolution of the temperature is 1 , the
temperature of the small changes may be numerical change
together
