Wet Bath Method Equipment Checklist for Wet Bath Sensitivity Check/Calibration Mixing the Wet Bath Solution (optional) Operating the Alcohol Wet Bath Simulator Readying the PAS V PAS V Sensitivity Checking PAS V Calibration Dry Gas Method Equipment Checklist for Dry Gas Sensitivity Check/Calibration...
Instructions for both wet bath and dry gas checking/calibrating are included in this manual. You may also choose to send your PAS V into the manufacturer (PAS Systems) to be calibrated.
Mixing the Wet Bath Solution (optional) Certified calibration solution (500 ml) is available from PAS Systems International but making your own calibration solution by diluting a stronger stock solution with distilled water is a simple process using the following steps. Stock Solution To mix your (water/ethanol) stock solution, use a 100 ml graduated cylinder for your mixing.
Operating the Alcohol Wet Bath Simulator On/Off Switch Inlet Tube Outlet to PAS V Heater ON Light The Alcohol Wet Bath Simulator The lower (jar) portion is filled with a heated solution of water and alcohol, which simulates the blood running through the arteries in the lungs. The upper portion (the head space) is filled with a mixture of air and alcohol that simulates the air in the lungs that is in contact with the blood across the cell membranes.
Be sure the battery is installed and fully charged, with the flashlight ON. There should be no blinking red battery light. Inspect the inlet/outlet ports of the PAS V to make sure that they are not clogged. Conduct an air blank: NOTE: Be sure the room air is free from alcohol and that the ambient temperature is above 50°F.
Check that the inlet and outlet ports of the PAS V are free of obstruction. Hold the PAS V and insert the tip of the Calibration Assembly firmly into the PAS inlet port.
NOTE Monitor the red low battery light of the PAS V to ensure that it does not start flashing during the calibration procedure. If it does, the battery must be charged before proceeding.

Press the Calibration Connector Tube nipple into the inlet port of the PAS V and hold tightly in place. Hold the PAS V with your thumb near the Sensor Control Button and press the regulator button so the gas begins flowing.
NOTE Monitor the red low battery light of the PAS V to ensure that it does not start flashing during the calibration procedure. If it does, the battery must be charged before proceeding.
To ensure that there is a record that these sensitivity checks have been conducted on a monthly basis, it is necessary to establish a log with a record for each of the PAS V units employed by the Company or Department. An example of such a record is shown below.
