The battery must only be replaced in a non-explosive atmosphere. Ensure
that the electronics are supplied with adequate ventilation with fresh air.
The battery can be changed during operation.
• All readings of the counter(s) and all counting parameters are retained.
• After changing the battery, the current time and date must be entered
again (coordinates X01 and X02; see chapter 4.3.3.9 Archive). In addition,
the battery change must be indicated in coordinate G25. This updates
the battery change date and sets the operating hours G26 to 0 and the
battery capacity G24 to 100 %.
• The current flow rate value is not stored during the change because
there is no additional battery buffering.
