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!
