Product Description:
1, The voltmeter with a fully enclosed shell, potted waterproof design, prolonged soaking in the water can still work without damage, more moisture, anti-oil, anti-vibration.
2, The voltmeter display device using 0.56-inch LED digital tube. Installation dimensions are safety compatible with Series 27 voltmeter.
3, the voltmeter wiring is simple, only need to take two lines, the table has anti-protection, then anti-burn.
4, The voltmeter starting voltage is low, only 2.5V red, green only 2.7V, blue only 3.0V can be measured correctly, in the same price two-wire voltmeter starting voltage called the world's lowest. Which will greatly facilitate the use of lithium battery, 18650 and other battery users. When the voltage is below 3.5V, the display brightness will darken, but does not affect the correct measurement.
5, In order to achieve the best measurement accuracy, the voltmeter will be based on the measurement of the voltage automatically move the decimal point of the location. In the measurement of the following 10V voltage, the decimal point after the display of two; in the measurement of 10V or more voltage, the decimal point after the display of a bit. That is able to take care of the battery user's need for measurement accuracy, but also to take into account the need to measure higher voltage.
6, The voltmeter can be used for motorcycles, cars and other monitoring battery voltage, timely grasp the battery status. It can also be used for other voltage measurement applications.
Technical Reference:
Dimensions: Length 50x Width 30x Thickness 27mm
Hole size: 46x27mm
Measuring range: red DC2.5-30V
Display color: red
Minimum input: Below minimum voltage measurement is inaccurate or not displayed
Maximum input: DC30V (above this voltage is the risk of burning)
Allowable error: 10V or less accurate to 0.01V, 10V or more accurate to 0.1V, allowing error of 1% (+/- 1 word)
Display: three 0.56 "LED digital tube
Refresh speed: about 200mS / time
Power supply: no power supply
Lead length: 20cm
Current consumption: less than 20mA, generally 5-15mA
Operating temperature -10 � ~ 65 �
Note: Do not use the 24V battery on a 24V battery. Because the battery is fully charged when the voltage close to the limit of the table, leaving the table to stay too small, charging and motor work will produce a higher voltage pulse.
