Test data appears in red font. What does this mean?
There are two cases when you will see red test data in FanTestic:
- Fan Pressure (flow pressure) is too low for the Range, which means you should change to a smaller, more restrictive, Range – During an Automatic test, the software would prompt you to change the Range in this case.
- During data collection, there was a data point collected as zero - This is caused by an instantaneous Fan pressure dropout, and the software displays this result in red to indicate data may have been skewed and should be retaken.
If you did not receive a prompt to change Range, most likely the problem is #2. In this case, you should just click the "Clear point" button to clear that specific data point and you can re-input data back into that specific point using Semi-Automatic mode via the "Begin Semi-Automatic" button.
