12v DC voltmeters


Recommended Posts


Self voltage measurement = 4.5-30 VDC

Seperatel supply measurement = 0-30 VDC

The same supplier has other 0-100 VDC (and 0-50ADC) that will require isolated supply which can be accomplished by using small cheap(ish) DC-DC converter.

Does that amp meter use a shunt or direct through the unit?

From the diagram it connects directly through the unit.

I have not connected them up yet, hopefully I will get a chance this weekend.
