Sampling
Before use, allow pump to equilibrate after
moving it from one temperature extreme to
another.
Protect sample pump from weather when in
use outdoors.
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 sample col-
lection media 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.
User Options During Sampling

compensate due to excessive back pressure or a low battery condition
exists the sampler will shut down. HOLD will display on the LCD
