Section 4.
Changing measurement resolution
The LI-3100C utilizes the full measurement width at all times, for both 0.1 and 1.0
mm
2
resolution. The 0.1 mm
2
resolution may be preferable , since it provides the
best accuracy, particularly with small or complex shaped objects to 0.5 mm in width.
The 1.0 mm
2
resolution may be preferable where large samples are being measured,
and the continuous buildup of debris on the belts causes excessive spurious counts.
Changing from 1.0 mm² to 0.1 mm² resolution
The procedures for the resolution change are outlined in the following steps.
1
Disconnect the power.
2 Remove the rear housing by removing the four retaining screws.
3 Move the decimal selector switch to the 0.1 mm
2
position (labeled near the switch). This switch is
located at the top right corner (as viewed from the rear of the display circuit board.
4
Loosen all four set screws on the outer camera pressure rail.
5 Align the red focus mark to the red lens index mark on the inner camera alignment rail.
