This small mini voltmeter for voltages from 3 to 30 V has a 3 digit 7-segment display (0.36 Inches). The measured value can be displayed with 1 or 2 decimal digits and is refreshed every 0.3 seconds. This measurement device is outstanding by its very low power consumption of less than 30 mA and can be mounted using the 2 mounting holes.
If a separate 3 V power supply is connected, voltages from 0 to 30 V can be measured.
