Notes on Battery Life
Battery life varies based on numerous factors including temperature, communication
usage, and various load options. To achieve the maximum battery life noted in the
product data sheet requires that you:
 Limit use of the display, backlight, and FBxWifi options.
 Limit communication activity.
 Disable power to all I/O (except for the MV or static pressure sensor, or RTD). To do
this, click Configure > I/O Setup > I/O Configuration > Properties and select
Disable for each I/O module.
