Position Correction - Omron ZFX-C10 User Manual

Position Correction

This function is used when the position or orientation of the measurement target is not fixed. If you use this
function, the amount of the shift from the reference position is calculated, and the position of the measurement
region is corrected before measurement is performed.
Important
After using an image for setting position correction, save the image to SD card.
Registering Images p.93
When adjusting by position correction, use a saved image. If you use an image different from the one that was initially
set to perform adjustments, position correction might not be set correctly.
To perform adjustments with a different image, repeat the settings for measurement items, too.

Note
• This section describes guidelines for selecting position correction items. The setup parameters for each item are
the same as those for the measurement items. For details, see those items.
• Normally, a single position correction is sufficient. However, to ensure reliable correction of positions or to shorten
the processing time, correct the position in 2 stages. [Position0] is the correction performed for the 1st position
correction, and [Position1] is the correction performed for the 2nd position correction.

1 model
If the measurement target
has a characteristic pattern,
the position of that pattern is
detected to correct the
position.
2 model
Two models are registered, and
the position difference is
corrected using the center
coordinates of a straight line
joining the two models and the
angle of that line to the horizontal.
