4.12. Channel Data Modeling

Channel Data Modeling is a unique feature to the Pur•Chek™ Pro. It allows the user to test refrigerants
that the analyzer may not already identify and "fingerprint" the data using the available channels. The
channel data is available for identified and unknown refrigerants.
Once you complete a test on an identified refrigerant (see list in section 4.8 Pure Refrigerants on page
11) or unknown refrigerants, the test results will display similar to Figure 4-12 A for identified refrigerants
or Figure 4-12 B for unknown refrigerants. Once displayed, the analyzer will allow the user to print.
Press the PRINT button and the data will appear on the printout similar to Figure 4-12 C.
This new feature allows the user to develop a "fingerprint" model for different refrigerants the Pur•Chek™
Pro may not already analyze. If the user tests a virgin tank of refrigerant at least 3 times and receives
channel data that is consistent or within a close range to one another, this data can be used as a
"fingerprint" model of that particular refrigerant. This feature will allow the user to have a guide to identify
refrigerants not already established by the analyzer and increases the capabilities of the Pur•Chek™ Pro.

NOTE: This is not a guaranteed method for identifying refrigerants. Results will vary and
some refrigerants may create inconsistent data.
