=== How the Tolerance Works ===

<table cellpadding=10>
<tr valign=top>
<td width=300>

<br><br>

The End Scan tolerance allows VTube-LASER to control which points are accepted as potential end-scan points based on how far the points are from the A-End and B-End Diameter values.<br><br>

The image illustrates a tolerance of 1 inch.   Any end scan points within that region will be qualified (the orange points).The red points are outside the tolerance, so they are rejected.<br><br>

The tolerance is measured from the out diameter in both directions - both positive (away from the centerline) and negative (toward the centerline).<br><br></td>

=== How to Set the Tolerance ===

<table cellpadding=10>
<tr valign=top>
<td width=500>
You can set the tolerance in two places in VTube.  One place is in the System Options / Measure 2 menu.</td>

<td width=500>
The second place to edit the value is in the VTube-LASER Measure Setup menu's "Other" tab menu.</td>

===Choosing Values===


<table cellpadding=10>
<tr valign=top>
<td width=500>
*A tight qualification is 0.039 inches (1 millimeter).  It is much more challenging to measure the end scan with a tight tolerance.  Keep in mind that tube deformation will make tight tolerance end scans more challenging.<br><br>

*A much easier / quicker qualification is to increase the value to much high number - like 1 inch (25.4 millimeters).<br><br>
*Some customers use large values (like 10 inches) to avoid this qualification from occurring completely - and making end scans much easier.<br><br>

===Set the Default===


<table cellpadding=10>
<tr valign=top>
<td width=500>
Set the default value by clearing the VTube project, then changing the value, then saving the setup to the default file in the System Options - Project Setup menu.<br>
