| SKC Catalog Number: | 100-3002, 210-5001, 210-5002 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | How long can a Leland Legacy or AirChek XR5000 battery pack be kept on the 223-241 charger? | | Answer: | The battery pack may be kept on the 223-241 charger indefinitely. |

| SKC Catalog Number: | 210-1002MH | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | Why is "back pressure" included in the Pocket Pump operating terms? What does this reading mean? | | Answer: | The Pocket Pump can be operated in two modes: constant flow mode and constant pressure mode. The pump keeps FLOW constant when in constant flow mode and PRESSURE is being kept constant when pump operates in constant pressure mode. The back pressure reading becomes important when the pump is in the constant pressure mode in the same way that a flow rate reading is important when the pump is in constant flow mode.
Constant pressure mode is used when one needs to sample through multiple tubes. You can find more information about constant pressure mode on page 21 of the Pocket Pump Operating Instructions at http://www.skcinc.com/instructions/37717.pdf |

| SKC Catalog Number: | 210-1002MH | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | Why do the Pocket Pump Operating Instructions recommend that I perform the initial battery charge of a new battery with the battery detached from the pump? | | Answer: | Completely charging the new battery pack detached from the Pocket Pump provides a slow charge that is best for the battery and provides optimum performance. |

| SKC Catalog Number: | 210-1002MH, 210- | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | What does the Pocket Pump FAIL display mean and how can I clear it? | | Answer: | FAIL may display for two reasons:
- When the pump is switched from HOLD to RUN it immediately jumps back to HOLD and scrolling through the display (by pressing the * key) reveals FAIL. This can be due to the battery pack having insufficient capacity to start the pump motor. This is not to be confused with a discharged battery pack that just needs recharged. The battery pack either has developed a fault or is at the end of its life.
- FAIL may display due to an internal problem with the electronics.
Resolution:
- Remove the battery pack and replace with a new charged battery pack. Run the pump and scroll through the display. If the pump runs and FAIL is not displayed, all is well
- If FAIL is still displayed, the fault is in the electronics and the pump should be sent to SKC for repair.

| SKC Catalog Number: | 210-2, 210-5, 224-4, 224-P, 224-5, 100-3 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | How do SKC Sample Pumps compensate flow? | | Answer: | Universal XR and AirChek 50 Series Pumps use a predictive flow control. Voltage applied to the pump motor and the current flowing through the motor windings are both sampled and controlled by the analogue driving circuit. The circuit is calibrated so that flow compensation within +/- 5% accuracy is achieved over the full range of flow and back pressure.
Leland Legacy, AirChek 2000, and AirChek XR5000 Pumps contain an isothermal flow sensor (U.S. Patent No. 5,892,160). It is a closed loop flow compensation system that directly measures airflow rather than having to rely on the predictive system. Airflow is being measured by monitoring pressure drop across the measurement tube installed in the pump's exhaust. The microprocessor continuously monitors and compares the pressure sensor output to the required flow reference and circuitry alters power applied to the motor if flow adjustment is needed. In addition, Leland Legacy and AirChek 2000 pumps both monitor temperature and atmospheric pressure so that the pump will compensate for changes in these parameters. |

| SKC Catalog Number: | 210-2002 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | Can the temperature and atmospheric pressure display be calibrated and adjusted? | | Answer: | It is possible to change the temperature and barometric pressure display in the AirChek 2000 pump. Using DataTrac 2000 with a live pump attached to the serial port of a PC, enter the Tools menu in the Pump Manager and select Temperature and Barometric Calibration. A Temperature and Barometric Pressure screen will display. Click on that screen to display the next screen. Click the up or down arrows to increase or decrease the temperature and pressure. CAUTION: Changing these settings may alter the sensor calibration. |

| SKC Catalog Number: | 210-2002 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | There is an F-21 code displayed on the LCD of my AirChek 2000 sample pump. What does it mean? | | Answer: | When an AirChek 2000 pump displays an F- code on its LCD, it is referring to a control board fault. Following are the possible F- codes, their definition, and remedies:
F-11, F-14, or F-21 NVRAM failed. Reset pump at user interface. Enter user interface. When CLr appears, press pump kepad up arrow 9 times. If problem recurs, send control board to SKC for repair.
F-31 or F-32 Atmospheric pressure sensor failed. Replace control board and top plate as a matched set (Cat. No. P79519) or send pump to SKC for repair.
F-33 or F-34 Temperature sensor failed. Check control board and temperature sensor connections and/or replace control board and top plate as a matched set (Cat. No. P79519). |

| SKC Catalog Number: | 210-5001 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | Are there special shipping regulations for the Li-Ion batteries in SKC AirChek XR5000, Leland Legacy, and QuickTake 30 sample pumps? | | Answer: | Rechargeable lithium-ion batteries for use with SKC sample pumps have been tested in accordance with the UN Manual and are proven to meet requirements of each test in the UN Manual of Test Criteria, Part III, subsection 38.3. They have a watt-hour (Wh) rating below 100.
Per 2010 IATA regulations, packaging must meet the specifications of and contain labeling and documentation required by IATA Packing Instructions 965, 966, and 967. See IATA Guidance Document: Transport of Lithium Metal and Lithium Ion Batteries, Revised for the 2010 Regulations. http://www.iata.org/SiteCollectionDocuments/Documents/GuidanceDocumentontheTransportofLiBatt_2010.pdf |

| SKC Catalog Number: | 210-5001 | | Category: | Sample Pumps | | Sub-category: | Sample Pumps | | Question: | How do I zero a 9999 timed run or delayed start setting on the AirChek XR5000 pump? | | Answer: | With the pump in a non-running state (no flashing blue LED):
- Press star, up arrow, down arrow, and star keys in sequence to enter user setup functions.
- Press the star key until the flashing Set Timed Run and min appear on the display.
- Press the up or down arrow key until time displays as 0.
- Press the star key to advance to Run Delay.
- Press the up or down arrow key until time displays as 0.
- Press the up and down arrow keys simultaneously to exit user setup functions. All time settings will be zeroed and the pump will be ready to run.
Note: Selecting CLr in the user setup functions after a sample run will clear accumulated run time only. It will not clear Timed Run or Run Delay time settings. |
