SMAKN 2 Wire Automatically Adjust Blue Dc 3.5-30v LED Panel Digital Display Voltage Meter Voltmeter
Display color: BLUE Display mode: Three 0.56 LED digital tube update rate: About 500 ms/time Physical size: 48 x 29 x 21.5 mm (LW H) Opening size: 45.5 x 26 mm (LW) Power supply: Don't need the power supply, direct use of the test voltage as a power supply Lead wire length: 14 cm The minimum input: 3.50V The maximum input: 30.0V Measurement range: DC3.50 - 30.0V Operation temperature: -10 degrees~65 degrees Measurement accuracy: ±(5‰ + 2 Digit) Red line:Power Supply +,Measure Voltage +,(3.50-30.0V DC) Black line:Power Supply -, Measure Voltage- If measure 10V below, accurate to 0.01V,display x.xx If measure 10V or more,accurate to 0.1V,display xx.x Note:Because the truck battery is fully charged voltage of about 28V. Especially when the truck starts immediately, the pulse interference is likely to damage the module. This table does not fit 24V truck. So if you counter this situation, please select the 15-80V voltmeter.
Product Features
- Connection is simple, just need to pick up two lines, a joint reverse protection, then do not burn
- Starting voltage is low, only 3.50 V, can correct measurement
- Variable precision: Precision automatic change below 10.0 V, the highest resolution of 0.01 V, Prec
- Can be used for measuring the car / battery car / motorcycle battery voltage, and other forms of vol
- Can be used in all kinds of voltage measurement purposes
