The calibration adjustment value will display beside the calibration icon.
Note: The fl ow rate displayed on the calibrator will change as a result of this adjustment.
Touch check mark to accept the calibration adjustment value and return to the Flow Menu.
The fl ow rate displayed on the pump will remain unchanged.
6. Disconnect representative sorbent tube from the calibrator. Replace representative sorbent tube with a newly opened unexposed
method-speci fi ed sorbent tube to complete the sampling train. See To sample on page 18.
To set up a multiple sorbent tube train and calibrate – Constant Flow Mode
* Charge pump battery completely before calibration and sampling.
* Use of an unapproved battery and/or charging cable could damage the pump and will void any warranty.
* Requires Constant Pressure Controller (CPC) and Multiple-tube Low Flow Holder accessories.
* See Adjustable Low Flow Holder Operating Instructions for details on holder operation.
* Calibrate/verify pump
fl ow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
1. Set fl ow rate on pump (see To set pump fl ow rate on page 13) . Important! Set
pump fl ow rate to ≥ 15% higher than the sum of the fl ow rates through all tubes
to be used during the multiple-tube sample run to ensure adequate air fl ow.
Note: The combined fl ow through all tubes cannot exceed 500 ml/min.
2. Press tubing from the outlet (unlabeled side) of a Constant Pressure
Controller (CPC) onto the pump inlet (Figure 4) .
3. Press tubing from the 224 Series Multiple-tube Low Flow Holder onto the
CPC inlet (labeled “To Sample” -
Figure 4 ).
4. Break tips o ff a representative sorbent tube and insert (arrow printed on
tube pointing toward the pump) into the rubber sleeve of a 224 Series
Multiple-tube Low Flow Holder
(Figure 4) . Repeat for additional tubes
up to the maximum number of holder ports or desired number of tube
samples.
Important! Fill unused tube holder ports with unopened
sorbent tubes to keep ports clean during sampling.
5. Label all sorbent tubes and ports.
6.
On the Multiple-tube Low Flow Holder, use a small fl at-head screwdriver
to turn counterclockwise the brass fl ow adjust screw directly beneath the
fi rst port holding an open sorbent tube. This opens the port to air fl ow.
7. Use a length of fl exible tubing to connect the exposed open end of the fi rst
port sorbent tube to a calibrator outlet (Figure 4) .
8. Calibrate pump fl ow rate through the tubes as follows:
