11.0Quality Assurance

11.1Leak Test Procedure

A quality assurance self-test feature is provided to verify proper integrity of the flow cell. It is recommended that the self-check leakage test be conducted periodically as part of an ongoing quality assurance program. Passing the leak test does not ensure proper function of the Cal=Trak. It does ensure that total leakage is within the product’s allowable limits. To ensure proper function of the Cal=Trak annual factory calibration is recommended. The leak test may take as long as 6 hours or more to complete per fitting.

Since the leak test may take several hours, it is recommended to plug the charger into the base during the leak test to prevent the unit from turning off.

To Initiate the Leak Test

1Place the Cal=Trak on a flat, vibration-free surface.

2While in the “Main Menu” install the leak test cable (included with the Cal=Trak base unit) between the 9-pin Cal=Trak Base Connector and the 9-pin Cell Connector.

From the “Main Menu” remove the cell and select “Leak Test”

After a leak test is initiated, the display will read:

Place the leak test plug over either the inlet or the outlet port fitting on the Cal=Trak flow cell. Invert the Cal=Trak flow cell

Push any key to commence the leak test. At this point the Cal=Trak will time the descent of the piston. The leak test may take up to 6 hours to complete. The display will read:
