The fit is successful but all points are marked as excluded

Document ID: DQ131
Relevant to following products: WorkOut 2.0 Manta
Document description: Problem: For certain fits all points are marked as excluded when using the Log/Anti Log Y setting

When using the Log/Anti-Log Y setting with a fit with a slight downward curve the fit is fine, however the software incorrectly excludes points reporting that they are out of the Y range when they are not.

When the calibration curve is almost a straight line, but curving upwards slightly this does not occur, the problem is only present with a downward curve. In the case of the Exponential Fit this is when the fit results in a negative K value.
