Adjusting The Background Filtering Level; Setting Noise Filtering - Omron ZG2 Series User Manual

Adjusting the background filtering level

Pixels in the received light image whose density is at the preset background filtering level
or less are judged to be noise, and can be omitted from the extraction target of the profile.
This enables profiles to be displayed stably even when measuring targets with poor
reflectance or when measurement is influenced by external light.
 FUN mode-[MEAS]-[IMAGE]-[CUT]
Setting value
0 to 255
Note
• The APS setting function enables the optimum value to be set.
APS function p.60
• If the profile cannot be detected normally even after changing the background filtering level
setting value, adjust the received light gain.

Setting noise filtering

Noise filtering is used when waveform breaks appear in the profile. Noise components,
the cause of waveform breaks, can be filtered out.

When the profile is disrupted by external light: Setting a higher
setting value enables the profile to be displayed normally.
