MATEE 3-Wire Digital Voltmeter DC 0.00-30.0V with Blue LED Display and Reverse Polarity Protection
MATEE 3-Wire Digital Voltmeter DC 0.00-30.0V with Blue LED Display and Reverse Polarity Protection
Features: With 3 wires design, able to measure the voltage below 3V as long as you provide power Requires extra power supply of 3.00V to 30.0V Three digital LED nixie tube provides bright and clear readouts Reverse polarity protection design prevents the voltmeter from burning out when wires are accessed reversely This small digital voltmeter can be mounted in tight spaces easily Suitable for all kinds of output voltage measurements, such as batteries on mowers, motorcycle, E-bike and scooter ±1% measurement accuracy means the error is ± 0.3V when voltage is greater than or equal to 10V; while the error is ± 0.10 when voltage less than 10V Notice 1: If the voltmeter is used to measure batteries, be sure it's switched off when not in use to prevent that small but steady drain Notice 2: The Voltmeter may be permanently damaged if the input voltage exceeds 30V!Specifications: Measurement Range: 0.00-30.0V Power Supply Range: DC 3.00-30.0V Max.Input: DC30V (The Voltmeter may be permanently damaged if the input voltage exceeds 30V!) Input Polarity: DC voltage Operation Current: <13mA Refresh Rate: About 300mS / times Measurement Accuracy: ±1%(It means the error is ± 0.3V when voltage is greater than or equal to 10V; while the error is ± 0.10 when voltage less than 10V) Display: Three digital LED nixie tube Display Color: Blue Lead Length: 20cm/7.87in Operating Temperature: -10~65°C (14~149°F) Size: 48x29x22mm / 1.89x1.14x0.87in Mounting Hole: 46x27mm / 1.81x1.06in Product Weight: 20g/0.71ozWiring Method: Red Wire: Power supply + (3.00~ 30.0V DC) White Wire: Measured Voltage + (0.00~ 30.0V DC) Black Wire: Power supply - ; Measured voltage - Package: 1 x Digital Voltage Meter
