Choosing a Display Mode
The default display is two lines and shows the calculated (exact) sarcomere spacing, fi rst
order diffraction distance that is used to calculate the sarcomere spacing and the signal
amplitude, which is used when you are aligning the camera. To toggle through the display
modes, press the
Display
button. Press one time to see the fi rst order diffraction distance.
Press it again to view the signal amplitude. Press it a third time to return to the sarcomere
spacing display.
