Save program
You specify what causes an image to be saved.
The addition of "(All)" means that all acquired images
are entered in the diagnostic buffer. If "Scan" is ena-
bled, this also includes images for which no read
result is output.
Activation of "Scan" under "Program > Image acqui-
sition > Control".
Example
"Scan" with 10 acquired images is set as the image
acquisition mode.
If the code to be read is only fully visible in the 5th
acquired image:
• With "Read OK (all)", the four previous images
are also stored in the diagnostic buffer.
•
With "Read OK", only the 5th image is stored.
"Poor quality evaluation" also includes images in
which a verification error occurred.
