For accurate measurement
For accurate measurement, refer to the figure shown below and make sure that a measuring object
is imaged at the center of the display as large as possible. Larger measuring area needs longer
distance.
Ensure a sufficient measuring area for accurate measurement.
For accurate measurement, 4 x 4 pixels or more are needed for a target area.
