===Why the End-Scan technique is important===

<table cellpadding=10>
<tr valign=top>
<td width=500>
This end-scan method is useful for ease-of-use and quickness.
<br><br>
Please keep in mind that our tests show that it is the least precise of the techniques that we recommend.
<br><br>
We also recommend the [[End-Scan Using the End Wall]] technique and the most precise [[End-Scan Using End Targets]].

===Measure Setup===
<table cellpadding=10>
<tr valign=top>
<td width=500>
* Set System Options, Measure 2 Tab, "Maximum Number of LLP Points in String" to 3
* Set Measure Setup - LASER Tab: The LASER defaults to ON for CYLINDERS and END-SCANS.
* Set Measure Setup - LASER Tab: Cylinder stripes = 3 to 5
* Set Measure Setup - LASER Tab: End-scan stripes = 5
* Set Measure Setup - LASER Tab: Split bend stripes = 5
* Set Measure Setup = Scan Rates Tab: Set all rates to TIMER for all scan types.
* Set Measure Setup = Scan Rates Tab: Set the Scan Rates TIMER is set to 0 for all TIMERS.

===How To Use This End-Scan Technique===

<table cellpadding=10>
<tr valign=top>
<td width=300>
* Align the scanner with a slight scissor angle across the end as is shown in the image on the right<br><br>
* For repeatability: Hold the probe still.<br><br>
** Holding the probe motionless during scanning is important.  If you move the probe during scanning the end, then repeatability will drop significantly because of exposure changes where the probe falls off the end of the tube.<br><br>
** Likewise, striking the same end location is important during each repeat measure.

*Press the green button until VTube-LASER is finished scanning all the end stripes.<br><br>
