Figure 42: Two file Comparison
One calibration file used to compare two test files is also useful. It permits the user to have a
standard to measure against for two separate tests. These might be tests that were done on
the same unit at different times to measure wear and tear, or to measure the difference before
and after rewedging, or tests done on the same model of a unit done on separate units to
measure consistency of performance.
If a calibration file has its loose reference wedge measurement higher than the tightest
wedge in the test file, then all wedges will be shown as loose as a result. On the other hand,
if the calibration file has its tight measure lower than the loosest measure in the test file, then
all wedges will be shown as tight.
