TSI Instruments AEROTRAK 9310, Operation Manual

Page: 23 / 91

Getting Started 2-5
To Install the Lithium-Ion Battery
1. Remove the battery door on the back of the instrument by turning the
two thumbscrews counterclockwise.
2. One battery is provided for the 28.3 and 50 L/min models, but up to
two batteries can be used to extend the run time. Two batteries are
provided for the 100 L/min model (Model 9500) and both must be
present for the unit to operate on batteries. This is due to the larger
power draw at the 100 L/min setpoint. Slide the battery into the slot (it
does not matter which one), pressing until it is flush with the back
panel (note the orientation of the tabs).
3. Replace the battery door and secure with the two thumbscrews.
4. The batteries will be charged if the instrument is on and not actively
taking a measurement. If you use the unit with batteries often, you
might also consider using the TSI external battery charger (see
Optional Accessories in Chapter 1).
N O T E
It is also possi
ble to “hot swap” batteries if you are careful. As long as
one charged battery is engaged at all times, a fully charged battery can
be inserted and then the depleted battery removed without powering
down the unit.

explosion and fire hazard. Do
