8.3 Battery replacement
Battery-equipped internal displays have a battery charge monitor. When the battery is
nearing the end of its capacity the screen will periodically flash the message LO BATTERY
and the BAT
indicator on the screen will flash. The recommended replacement interval for
models using the battery as a primary power source is determined by the power and
feature use, as shown in Table 1-1. Replace the battery when the low battery indication
appears on the screen.
The total is backed up in non-volatile memory when the low battery monitor is tripped. It is
recommended that an updated reading be manually backed up prior to changing out the
battery.
