Spec*Edge Version 3.9
June 11, 2008
Setup - 10
2.2 Calibration:
Spec*Edge uses UMAX scanners with high resolution 800 x 800 or 700 x
700 dpi or pixels to measure in small increments. The number of pixels per inch
may vary by 1 or 2 depending on each individual scanner. To accommodate the
slight differences in pixel count from one UMAX Mirage IIse or PowerLook 2100
scanner to another, Spec*Edge has introduced a calibration algorithm which
accounts for these slight variations. To obtain correct measurement you should
calibrate Spec*Edge
™
each time it is turned on, a different sized sheet is measured
or the orientation on the sheet is changed. To calibrate Spec*Edge:
Step 1: Place a controlled target (a sheet known to meet the
specification) of a verified measurement on the scanner,
Step 2: Select a sheet size (or develop a setting) for the length and width
of the controlled target.
Step 3: Scan the target several (6) times to insure that the scanner is
totally warmed.
Step 4: Enter the Setup Screen and click on the calibrate button.
The X-Cal Value: shows the actual number of pixels across one square
inch.
The Y-Cal Value: shows the actual number of pixels horizontally in one
square inch
2.4 Returning To the Operator Screen:
After the required measurements have been set, the operator then clicks with
the left mouse button on the <Back> button and the settings are locked in place
and password protected.
