Installing the battery pack
Be sure to read “Using Battery Pack” (p. 9).
The battery pack is subject to self-discharge. Be sure to charge the battery pack before initial use
(See Step 7).
If the battery can only be used for a considerably short time even after correct charging, replace it
with a new battery pack.

• The battery pack is used as a backup power supply for the instrument during interruption. When fully
charged, it can provide backup power for approximately 8 hours in the event of an interruption.
• Note that if an interruption occurs while the battery pack is not being used, the displayed time series data will
be erased. (Data that has been recorded on the SD memory card and instrument’s internal memory will be
retained.)
• For more information about the operating temperature and humidity and the storage temperature and
humidity, see “14.1 General Specications” (p. 153).
