Getting Started
Charge the Lithium-Ion Battery Pack
• Completely charge a new battery pack before operating the pump. It may be necessary to charge the
battery a few times before maximum battery capacity is achieved.
• Intrinsic safety circuitry inside the battery causes the pump to self-discharge during storage. Charge battery
completely before calibration and sampling to achieve optimum pump operation.
• After charging the battery pack, it is good practice to run the pump for approximately 5 minutes before
calibrating. This ensures the battery is in more steady-state conditions and improves the agreement in pre
and post-sampling calibrations.
• The battery pack may be kept on SKC-approved Li-Ion battery chargers for an indefinite time.
1. For a complete charge, ensure the pump is not running. Insert plug on charging unit into the
baery charging jack on back of pump. Ensure plug is oriented so that the arrow on the plug is
facing upward.
Ensure proper orientation of charging cable before plugging it into the charging jack.
Improper orientation/contact will short circuit the battery and voids any warranty.
Short circuiting the battery pack will render it immediately inoperative.
2. Insert plug on power supply into jack on charging unit.
3. Pull locking tab to side and insert appropriate wall plug into power supply.
Release locking tab. Plug power supply into a wall outlet.
4. The standard 2-cell Li-Ion baery pack will recharge in approximately 4 hours. The high-power
4-cell Li-Ion baery pack will recharge in approximately 8 hours. Run pump for 5 minutes
after charging is complete.
Reading the Charging Status LED on the Single Charger
The Li-Ion Charging Unit (Cat. No. P22300) indicates baery charge status via an LED on the unit that blinks in specific paerns.
Observe the LED steadily for > 5 seconds to read charge status (see below).

Determining Battery Charge
Three bars indicate a full charge (normally appears after charging), approximately 75 to 100%.
Two bars indicate the baery is charged enough to operate the pump, approximately 25 to 75%.
One bar indicates baery charge is low (charge baery), approximately 1 to 25%.
No bars indicate that low baery fault is imminent.
Low Baery Fault
No bars and a flashing outline indicate a low baery fault (pump will go into Hold and go to sleep after 15 seconds in low baery fault).
Accumulated run time will be retained.

Operation
High Flow Applications (1 to 5 L/min)
Set/Calibrate Flow Rate
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before calibration and sampling.
1. Ensure that baery is fully charged and that pump has run for 5 minutes before calibrating.
2. Prepare the calibrator. See calibrator instructions.
3. Set up a calibration train (see above): Using flexible tubing, connect the calibrator outlet (suction port) to the representative sample
medium inlet. Using 1/4-inch Tygon tubing, connect the sample medium outlet to the pump inlet.
4. With pump in a non-running state (no flashing blue LED), set the desired pump flow rate as follows:
a. Press to enter user setup functions.
b. Press until “ADJ” and “Flow” flash on display. Press to increase flow. Press to decrease flow (dashed
lines will move up or down on the display to indicate graphically the direction of the adjustment) until the
calibrator indicates the method-specified flow rate. Flow rate will not display on pump LCD. Observe the
calibrator to determine flow rate. Once the desired flow rate is indicated on the calibrator (within ± 5%),
press [] to accept flow seing and to exit user setup functions. Take a minimum of three readings and
record the average flow rate, as per OSHA/NIOSH instructions. The pump is ready to run.
• Changing the flow rate in user setup functions will not clear accumulated run time.
• Changing the timed run and/or run delay settings in user setup functions will automatically clear accumulated run time.
5. Disconnect the calibrator and flexible tubing from the representative sample medium and proceed to Set Up/Sample.
Set Up/Sample
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from weather when sampling outdoors.
• Use of any device or battery pack other than Cat. Nos. P85004 and P84002 to power the pump voids the UL Listing for intrinsic safety.
• Charge pump battery completely before calibration and sampling.
1. Replace sample medium with new unexposed medium for sample collection.
2. Place the sample medium where appropriate for sampling. For personal sampling, clip the sample collection medium to
the worker in the breathing zone and the pump to the worker’s belt using the belt clip.
When using an impinger, place an in-line trap between the pump and impinger to prevent fumes from accidentally being
drawn into the sampler. Failure to use an appropriate in-line trap during impinger sampling voids any warranty.
3. Start a continuous or timed sample run by pressing []. Record start time and other pertinent information.
• Sampling will start automatically if a run delay is set and initiated. Sampling will stop automatically if a timed run is set and initiated.
•For automatic start and stop, set and initiate both a run delay and a timed run.

Low Flow Applications (5 to 500 ml/min)
• Single-tube sampling requires the All-in-One low flow adjustable tube holder; see the operating instructions for the All-in-One for details on its operation.
• Multiple-tube sampling requires a Constant Pressure Controller (CPC) and a Dual, Tri, or Quad Adjustable Low Flow Tube Holder accessory;
see the operating instructions for the CPC and Adjustable Low Flow Tube Holder for details on their operation.
Using the All-in-One Adjustable Tube Holder
Set/Calibrate Flow Rate for Single Tube
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before calibration and sampling.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
• The flow rate through the pump is set first and then the flow rate through the sorbent tube is calibrated.
• Two small inlet holes on the bottom of the built-in CPC of the All-in-One can become blocked. Periodically inspect and, if needed, clean with a small
pick and blow particles away with a puff of air.
Pump Flow Rate
1. Ensure that baery is fully charged and that pump has run for 5 minutes before calibrating.
2. Prepare the calibrator (see calibrator instructions). Using flexible tubing, connect the calibrator outlet (suction port) to the pump inlet.
3. With the pump in a non-running state (no flashing blue LED), set the pump flow rate to 1.5 L/min as follows:
a. Press to enter user setup functions.
b. Press until “ADJ” and “Flow” flash on display. Press to increase flow. Press to decrease
flow (dashed lines will move up or down on the display to indicate graphically the direction of the

• Changing the timed run and/or run delay settings in user setup functions will automatically clear accumulated run time.
4. Remove tubing from the pump inlet.
Flow Rate Through Sorbent Tube
1. Aach the Tygon tubing from the All-in-One to the pump inlet. See right. Break tips
offthe representative sorbent tube and insert it into the rubber sleeve on the holder
(arrow on tube pointing toward pump). Ensure that the sorbent tube fits snugly in
the rubber sleeve prior to sampling to avoid any air leakage. Two sleeves, each a
different inner diameter, are supplied with the All-in-One.
If the pump flow faults shortly after attaching the tube holder, check that the needle
valve on the All-in-One is open by using a small flat-head screwdriver to turn the
flow adjust screw on the holder slightly counterclockwise. If the flow fault continues,
check that the two small holes on the bottom of the built-in CPC are not blocked.
2. Using flexible tubing, connect the exposed end of the sorbent tube to the calibrator
outlet (suction port).
3. Adjust the flow rate through the sorbent tube using a small flat-head screwdriver to turn the flow adjust
screw on the holder (see right) counterclockwise to increase flow or clockwise to decrease flow until the
calibrator indicates the method-specified flow rate. Do not adjust flow rate on the pump.
Do not shut off flow completely with flow adjust screw or use an oversize screwdriver to adjust flow—valve
or thread seat damage may result.
4. When calibration is complete, disconnect the calibrator and tubing from the sorbent tube inlet.
Turn screw on holder

on the holder (arrow on each tube pointing toward pump). Place unopened tubes in any
unused ports to “seal” them.
3. Label all tubes and ports.
4. Using flexible tubing, connect the exposed end of the tube to the calibrator outlet (suction port).
5. Loosen and turn the brass flow adjust screw (see right) directly beneath the port holding the first
active tube to be calibrated (clockwise to increase, counterclockwise to decrease) until the calibrator
indicates the method-specified flow rate. Do not adjust the flow rate on the pump. Note: For tri and
quad models, first rotate each anti-tamper cover to expose the flow adjust screws, then adjust the appropriate
one until the calibrator indicates the desired flow.
6. Repeat Steps 4 and 5 for each active tube.
7. Once flow is calibrated for each active tube, it is recommended practice to re-check the flow rate
through representative tubes before removing them. Any adjustment should be minimal. Turn screw on holder
to adjust flow.

Set Up/Sample with Multiple Tubes
• Requires Constant Pressure Controller (CPC) and Adjustable Low Flow Tube Holder (see Accessories). The low flow tube holder used with CPC
allows up to four tube samples to be taken simultaneously, each at different flow rates if desired.
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
• Protect sample pump from weather when sampling outdoors.
• Use of any device or battery pack other than P85004 or P84002 to power the pump voids the UL Listing for intrinsic safety.
• Charge pump battery completely before calibration and sampling.
1. Replace representative sorbent tubes used for calibration with new unexposed tubes for sample collection.
2. Place a tube cover over each tube and thread into place on holder until secure.
3. Place the adjustable holder with tubes where appropriate for sampling. For personal sampling, clip the sample collection media to
the worker in the breathing zone and the pump to the worker’s belt using the belt clip.
4. Start a continuous or timed sample run by pressing []. Record start time and other pertinent information.
• Sampling will start automatically if a run delay is set and initiated. Sampling will stop automatically if a timed run is set and
initiated.
• For automatic start and stop, set and initiate both a run delay and a timed run.
5. Sample for the time specified in the method used. Accumulated run time will display on the LCD.
6. To stop a sample run, press []. This places the pump in Hold. Record stop time and other pertinent
information.
a. To resume sample run without clearing accumulated run time, press [].
b. To clear accumulated run time, ensure pump is in Hold, press to enter user setup functions, and
press [] when CLr displays.

To clear a flow fault and the flow fault icon, determine the cause of the fault, remedy the fault cause, and press[]
to remove the icon from the LCD and restart the pump.
Note: A low battery fault may occur instead of a flow fault when there is a low battery charge at the time of the fault, excessive back
pressure, and/or when there is a very short distance between the restriction and the pump inlet (e.g., finger fault versus pinched tubing).
The flow fault icon will not appear and auto-restart will not be activated under these conditions. A low battery fault icon will appear
instead and the pump will go to Sleep.
If pump goes to Sleep while in flow fault, the flow fault icon may remain displayed on the LCD when the pump is subsequently turned on. To
remove the icon from the LCD, ensure pump is in Hold, press to enter user setup functions, and press [] when “CLr” appears.
7. Cap the sample tubes and send with blanks and pertinent sampling information to a laboratory for analysis.
8. Verify the flow.
a. Turn on the pump and reinstate the calibration train and sampling media.
b. Take three readings and record the average value as the post-sample flow rate. Do not adjust the pump flow rate during this step.
c. Compare the pre and post-sample flow rates. Note in sampling documentation if the values differ by more than ± 5%.
