0-100V DC VOLTMETER, BLUE DIGITS 
Reviewer:
John K.
from Indiana, USA
This meter is good as a measurement device for a full wave DC power supply with an added leveling capacitor ONLY. I tried it with a wall-plug-in DC transformer and it shows random voltage (I assume this is a sample reading from the DC waveform produced by this type of device). I tried it with a fully-rectified DC power supply with a leveling capacitor and its readings are at the correct level and consistent. Easy to mount and wire into a system.
