Reading Bar Codes
If the BHT fails to read due to specular effects
or other factors, change the scanning angle of
the reading window or the distance from codes
as shown at right, and try it again. (Specular
effects occur when the reflection of the light
from the bar code becomes excessively strong.
This can easily happen when the reflecting
surface is polished or covered with vinyl.)
The laser light indicates the scanning range as a guide. The indicated
scanning range will deviate a little bit from the actual one. Keep the
BHT so that the laser light comes to almost the center of the bar code
height.
The BHT can read bar codes at a maximum distance of 40 cm (15.7")*
from the reading window. (*For details about the scanning conditions,
refer to the BHT-100QF/100BF User’s Manual.)
The bar code reading procedure may differ depending upon the
application used, so follow the application's manual.
Turn the BHT power on, bring the bar-code reading window to the bar code
to be scanned, and press the trigger switch. The BHT emits a laser light to
indicate the scanning range and turns on the illumination LED to scan the bar
code.
When the BHT has read the bar code successfully, the indicator LED will
illuminate in green.
