V1 Series Voltmeter

Shouldn’t you really be measuring the voltage at the battery (or other operation point) rather than at the gauge? No, they’re not the same, due to voltage drops on the power wires to the gauge. The more current drawn by a circuit on the line, the greater the voltage drop. These P.O.L. (point-of-load) voltmeters have separate lines for powering the gauge and for the point to be measured. With negligible load on the remote-sense wire, you get a much more accurate reading of the voltage being measured.

Measurement range: 0V to 27.5V D.C.
User-settable under and over-voltage alarms with startup delay
Park-light dimmer
User-settable day and night intensities (9 levels each)
12-segment bargraph AND 3-digit numeric display

Sensor required:
None
