Performing camera skew calibrations
Small amounts of rotational camera misalignment exists in most camera mounting systems. The camera
skew calibration measures this misalignment and applies a skew compensation to subsequent measure-
ments to eliminate the effect of rotational misalignments.
To perform a camera skew calibration:
1 Touch the Magnification button to cycle to the lowest magnification.
2 Touch the CAL button.
3 The video screen will be displayed with instructions
for performing the calibration in the upper left corner.
Follow the instructions to complete the calibration.
NOTE
Systems should be aligned mechani-
cally to within a few degrees. This
calibration is not intended as a substi-
tute for good mechanical alignment.
Specifying camera type
The QC-300 video camera input supports four popular video standards:
• NTSC • NTSC Y/C • PAL • PAL Y/C
Touch the Camera Type choice field repeatedly to cycle to the desired video input standard.
