Adjust Power Settings on a Field Gauge
This article will show you how to adjust settings for:
- Backlight Brightness
- Backlight Auto Off
- Auto Power Off
Backlight
The backlight on a Field Gauge makes it easier to read the information on the display when it is on. Because the backlight draws more power from the AA batteries when it is lit, we’ve given you the ability to adjust settings to get the ideal balance between visibility & battery power management, depending on your preferences and work environment.

Auto Power Off
This feature allows you to pre-determine when, and if, you want the Field Gauge to power off on its own to conserve battery life.
