S CLASS™ 2 cutter

2.4 How to make sure the sign has the correct size

(Length Calibration)
The S CLASS 2 cutters are friction-feed machines. This means that the cutting length
depends 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 2 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 the media, and mount the 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 Settings
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 below.

NOTE: The cutter will only be as accurate as the accuracy of the calibration itself.
If the ruler (measuring device) is inaccurate, then re-calibrating may worsen the
cutter's accuracy. The accuracy of the calibration will be reflected directly in the
cuts. Set the cutter to Metric to do the calibration. It is more accurate than the
English unit system (see section 0).
