HakkaDeal V56D Waterproof DC2.50-30V Red Display Digital Voltmeter
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 ¡æ ~ 65 ¡æ 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.
