2.5 How to Make Sure the Sign Has the Correct Size
(Length Calibration)
The S CLASS™ cutters are friction-feed machines. This means that the cutting length is
dependent on the thickness of the material.
The cutters have been calibrated in the factory for standard 2-mil cast or 3-mil calendared
vinyl. Each user (the S CLASS™ has a total of 8) can hold a different calibration factor.
This is very helpful for multi-colored signs; it ensures that the parts in different colors match
up, even if different types of vinyl media are used.
NOTE: For standard use, it is not necessary to calibrate the machine. With standard vinyl
the accuracy is within 0.2%. However if high accuracy between different vinyl or colors is
needed, then calibration is necessary.
Calibrating the media (Length calibration):
1. Power on the cutter, load media, and mount knife (see section 1).
NOTE: The wider and longer the loaded media, the more accurate the calibration will be.
Use a piece of vinyl of maximum width and a length that is approximately 1.5 times the
width.
2. Press .
The main menu will appear on the screen.
3. Press
.
The different tests and calibration routines will appear on screen.
4. Press .
The cutter will reload the media and perform the length calibration test. Take out the media
and measure the length of the cut line with a ruler (measuring device). The length that has to
be entered is the distance between line 1 and line 2 as shown in the figure.

2-7 LENGTH CALIBRATION PATTERN
NOTE: The cutter will only be as accurate as the accuracy of the calibration. If the ruler
(measuring device) is inaccurate, then re-calibrating may make the cutter’s accuracy worse.
The accuracy of calibration will be directly reflected in the cuts. Set the cutter to Metric to
do the calibration. It is more accurate than the English unit system (see :Panel Units).
