Mounting:
The gauge requires a round hole 2-1/16" in diameter. The gauge should be inserted into the opening from
the front and the U-clamp will be installed from the back. Tighten the two nuts on the U-clamp so that the gauge is
secure. Gauge depth to the back of the case is 1". Gauge depth including the mounting studs is 1-7/8".
Factory settings:
Lo warning point:
Hi warning point:

The voltage gauge will light with 8.0 – 17.0VDC on the PWR terminal. The SND terminal can monitor voltages
between 1.0 - 18.0VDC if monitoring another source..

The gauge has a user adjustable lower and upper warning level, which can be set to indicate low voltage and
overcharging conditions.
The SND terminal is the voltage sensing input. To read the vehicle system voltage, connect this to the PWR
terminal. To read the voltage at a second battery or other remote location, connect a wire from the SND terminal to
the voltage to be monitored.
