Measuring and Gauging Tools,Maserfaliw Digital Voltmeter,0.56inch Mini LED Digital Volt Voltage Panel Meter DC 4.5V-30.0V Voltmeter - Blue

Specifications: Measuring range: red DC4.50-30.0V, green DC 4.70-30.0V, blue DC5.00-30.0V Power supply range: no need to supply power separately, directly use the measured voltage as the power supply, the scope is the same as above. The highest input is DC30.0V. (Note: The input voltage is higher than 30V and may be permanently damaged) The tolerance is ±1%. The error is ±0.3V when it is greater than or equal to 10V, and the error is ±0.10 when it is less than 10V. Type: Digital Voltmeter Input Impedance: >100Kohms Operating Current: Red
