Can I run the same test setup (setup save) so I don't have to redefine the test each time?
Can I test more than one incubator without returning to my PC or uploading to my PC?
No. The INCU is designed to collect data from one incubator at a time. At the completion of each incubator test, the data can be uploaded to the PC using the INCU PC software, and can then be archived to storage media (hard drive, external drive, CD ROM, etc).
How can I export data directly from INCU to Microsoft EXCEL?
Although the INCU PC software wasn't originally designed to export data directly to EXCEL, this option does exist. The INCU Operator's Manual, Appendix C, contains the data file format for exporting INCU data to a database. Converting the saved INCU data file to a semicolon delimited file will help in importing the data into EXCEL. The process may take several steps.
INCU data format:
- All the data must be divided by 10 except for air-flow data
- Air flow data must be divided by 100.
- The character "M" preceding the value indicates an event marker. This character must be suppressed from the all data to obtain a numeric value.
Why doesn't the INCU include an integrated oxygen analyzer?
The INCU uses a hot-wire anemometer to measure air flow within the incubator. Since heat and enriched oxygen environments don't mix due to increased potential for flammability, evaluating the oxygen concentration should be done separately from the rest of the testing. Fluke Biomedical offers the max02 PLUS AE Oxygen Monitor, ideal for this type of analysis.
Why is it necessary to set the INCU test duration for 2 hours?
The laws of thermal dynamics come into play, as well as the need to evaluate the temperature-control circuit operations sufficiently. It takes time for the incubator chamber to warm up (equilibrate) to the temperature control value set on the incubator controls. Once the chamber is at a uniform temperature (as evaluated by the four separate, but simultaneous, thermistor measurements), the temperature control-circuit operation can best be evaluated. It would be expected that the temperature be controlled within the accuracy band provided in the incubator manufacturer's specifications. This should also agree with the IEC Standard requirements. Shorter test durations may not catch faulty temperature control circuitry.
