Battery Replacement
Battery-equipped models have a battery charge monitor. When the battery is nearing
the end of its capacity the screen will periodically flash the message LO BATTERY. The
recommended replacement interval for models using the battery as a primary power
source (without DC power at P+ terminal) is three years or within 30 days of the first low
battery indication on the screen. Replacement interval on models that use battery as
backup during short and infrequent DC power loss is ten years. The total is backed up
in non-volatile memory when the low battery monitor trips. It is recommended that an
updated reading be manually backed up prior to changing out the battery. Refer to
information on preparing the meter for battery change in Servicing the Meter (SERVICE)
on page 47 before changing battery.
WARNING
Fire, explosion and burns may result if not handled properly. Do
not recharge, short circuit, crush, disassemble, heat above 100°C
(212°F), incinerate, or expose contents to water.
Battery disposal should be in accordance with applicable
regulations, which vary by location. In many locations trashing of
used batteries is forbidden and disposal is done through local
battery disposal facilities. Spent batteries should be packaged in
such a way as to prevent short circuits during handling and
transport.
