Setting-Up
The DUSTTRAK monitor is now safely secured. When access is needed to the
keypad covered by the Velcro strap, loosen it to expose them. Be sure to
reattach the strap when done using the keypad
.
Connecting Tubing
A length of tubing is provided to transport the aerosol from the external inlet
to the D
USTTRAK inlet. Before attempting to sample, make sure that this
tubing is securely fastened to the barbs from both of the inlets. When closing
the enclosure, make sure that this tube does not get kinked. The best way to
prevent this is to pull the tube towards the front of the box as you close it
(see Figure B-10).

Supplying Power to the D
USTTRAK Aerosol Monitor
The Model 8520 D
USTTRAK Aerosol Monitor may be powered in one of two
ways when used with the 8520-1
Environmental Enclosure:
1. Using the standard internal battery pack (consisting of 4, C size
batteries)
2. Using the supplied external battery pack.
The internal battery pack will supply power for approximately 16 hours of
operation (may be less under cold conditions). This is adequate for single
shift (8-hour) monitoring, but will not work for 24-hour operation.
