
When using AC power, the battery (if installed) charges when the
instrument is on, while actively sampling (trickle charging), and
when the power is put in standby
—charge battery mode.

Removing/changing the lithium-ion battery or disconnecting AC
power does not cause loss of data. The AeroTrak ® Airborne Particle
Counter has an internal, non-user accessible battery to maintain
settings and save logged data.

Note that the battery provided has a built-in indicator of charge level.
Push on the “Check” button to see the charge level. If none of the
LEDs lights up, the battery is not charged.
