Setting or Verifying Flow Rate
When performing multiple-tube sampling using an adjustable
low fl ow holder (dual, tri, or quad), ensure the regulator has been
activated and the pump fl ow rate is set at 1.5 L/min. The maximum
fl ow rate through any one tube is 500 ml/min*. Calculate the sum
of all tube fl ow rates. If the sum is ≤1000 ml/min, proceed with
calibration and sampling without any further adjustment to the
pump fl ow rate. If the sum is >1000 ml/min, set the pump fl ow rate
15% higher than the sum of tube fl ow rates.
* Back pressure across some sample tubes can be higher than average. In
these instances, the maximum fl ow rate of 500 ml/min per tube may not be
achieved.
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
Ensure pump has run for five minutes before proceeding with
calibration.
Ensure the pump is set for low fl ow. See Activating the Regulator,
page 9.
Connect the adjustable low flow holder (Figure 4, page 13)
to the pump intake (Figure 2, #9) using 1/4-inch Tygon tubing.

Insert an opened sorbent tube into each rubber sleeve of the low
fl ow holder (Figure 4, #3 and 4) with the arrow on the tube pointing
toward the holder.
If sampling with fewer tubes than number of ports, insert
unopened sorbent tubes in the empty ports to seal them.
Connect holder to
pump intake and tube
inlet to calibrator.
Note the fl ow rates specifi ed by each sampling method and
add them together. If the sum is ≤1000 ml/min, proceed to
the next step. If the sum is >1000 ml/min, multiply the total
tube fl ow rate by 1.15 and set the pump for that fl ow rate.
Connect a calibrator to the exposed end of a sorbent tube,
loosen the brass fl ow adjust screw on the low fl ow holder, and
activate the pump by pressing Flow and Battery Check.
continued on page 15
14
Turn the fl ow adjust screw (Figure 4, #2) for the appropriate
port of the low fl ow holder until the desired fl ow rate is
achieved through the tube. Turn clockwise to decrease the
fl ow.
Do not adjust the fl ow on the pump. Adjust the fl ow only by
using the fl ow adjust screw on the low fl ow holder.
Do not exceed 500 ml/min fl ow rate per tube.

When the desired fl ow is set on the
initial tube, place pump in Hold by
pressing Flow and Battery Check.
Remove the calibrator from the tube
and connect to the exposed end of
the next sorbent tube. Press Flow and
Battery Check and repeat the fl ow
adjustment process until all tubes are
fl ow calibrated. Changing the fl ow on
one tube will not affect the fl ow rate
through the remaining tubes.
Do not exceed 500 ml/min fl ow rate per tube.
For tri and quad models, fi rst rotate each anti-tamper cover
(Figures 4 [on page 13] and 5) to expose the fl ow adjust
screws, then adjust the appropriate screw until calibrator
indicates the desired fl ow.
When the fl ow rate is set for each tube, press Flow and

so voids any warranty and UL Listing for intrinsic safety.
Use of any device other than the approved battery pack to power the
pump voids the UL Listing for intrinsic safety and any warranty.
