Replace the sorbent tube used for setting the fl ow with a new
unexposed sorbent tube for sample collection.
Place the appropriate size tube cover over the tube, and screw it into
place on the low fl ow holder.
Sampling
Before use, allow pump to
equilibrate after moving it
from one temperature extreme
to another.
Protect sample pump from
weather when in use out-
doors.
Use of any device other than
the approved battery pack
to power the pump voids the
UL Listing for intrinsic safety
and any warranty.
For personal sampling, clip the
low fl ow holder to the worker in
the breathing zone.
While the LCD displays HOLD, start sampling by pressing Start/
Hold. SAMPLE RUNNING will display. Record the start time.
The LCD will automatically track sampling period time elapsed.
At the end of the sampling period, press Start/Hold and record the
stop time.
To return to high fl ow, remove the low fl ow holder and
de-activate the regulator. See page 6.
For user options during sampling, see page 7.
Clip holder to worker and
pump to belt.
