Caution
TSI does not recommend using the standard AC adapter when
operating outside. This device is not rated for external
exposure.
Using the External Battery Pack
The battery packs supplied with the Environmental Enclosure allow for
extended use of the D
USTTRAK monitor. These battery packs enable the
D
USTTRAK monitor to operate for at least 24 hours (even in cold
conditions). The battery packs should be rotated and properly charged
after each use, to ensure a prolonged lifetime (see Maintenance section
for further information). Make sure that the internal C size batteries are
installed correctly within the D
USTTRAK monitor to make it possible to
continue sampling when changing the external battery packs
.
Install External Battery Pack
To correctly install the Battery Pack follow the instructions below:
• Slip the free end of the Velcro strap through the slot on the battery
pack portion of the main bracket (See Figure B-11).
Figure B–11: Slip Velcro Strap Through Slot.
• Slide the battery pack into the correct space in the sheet metal
bracket such that the leads are oriented up, and the PC board is in
the upper left hand quarter.
• Tighten the Velcro strap around the battery pack (See Figure B-12).
