Battery Save Mode
The RM12-2 will automatically go into a power saving sleep mode after 24 hours without a charging voltage present from a battery charger or alternator. During the sleep mode the remote meter will momentary flash every three seconds. The meter includes a front mounted "Wake" button. Pressing the "Wake" button will turn ON the remote meter and place it into the normal display mode for an additional 24 hours. In addition, any time the meter sees a charging voltage of 13.0 volts or higher, the meter automatically wakes up and switches to the normal operating display mode for the next 24 hours.
Auto Bright Technology
The RM12-2 features Auto Bright Technology which will auto-adjust the meter’s display brightness to the surrounding ambient light level. For example, on a bright sunny day the LCD meter will auto adjust to its brightest level. Conversely, in a nighttime or dark environment, the LCD meter will auto dim to a lower light level so it is not to overwhelmingly bright during low light conditions. The RM-12-2 features 6 brightness display levels that are automatically adjusted based on the ambient light level from the meters built-in photo cell.
Depending on your installation requirements, the RM-12-2 Remote Meter is very versatile and may be installed in a variety of locations.
If this meter is to be mounted in an exposed area, apply a small bead of silicone to the underside flange of the remote meter to reduce the chance of getting moisture behind the meter where the connection points are located. Mount the meter using (4) screws with (4) lock washers and (4) nuts (user supplied). Please see the included mounting template on page 4 on your documentation for mounting your RM12-2 remote meter.
