LazerView Usage Summary

Usage Summary:

 

Scanner Placement

Figure below shows the placement of the scanner on a wheel. Three magnets on the main bracket hold the scanner against the flange wall on three spacer pins. The scanner must be placed in such a way that both holder pins touch the top of the flange.

The scanner cable can be plugged into the connector on the scanner housing. Notice the connector is a push/pull type and you do not need to turn the connector to release it.

The other end of the cable must be plugged into the Scanner input connector (12-pin Female connector) on the handheld unit that is marked by a red arrow, titled Scanner.

Rim Index Adjustment

Rim index is used to measure the rim thickness of the wheel. The index has a triangular piece on its top and a pin down on its bottom end. The pin is designed to touch the bottom edge of the flange wall, where a gauge is used to read the rim thickness (See Figure)

 

You may need to adjust the length of the pin to touch the appropriate point. The pin is pre-adjusted to common wheel types in use.

Scanning

After the scanner is placed on the wheel and the rim index is adjusted, wheel profile scanning can be performed.

To scan the wheel, position the scanner towards the tread end of the wheel and manually rotate it pass through the flange and onto the rim index. A scan progress bar is shown on the PDA. As soon as the progress bar is completed, a sound from PDA will notify you of the end of the scan. Make sure that the sound level on your device is high.

      

 

Witness Groove Measurement(Optional):                                                      

In locomotive wheel measurements, wheel diameter is usually measured using witness groove as a reference. LazerView is equipped with an option which uses witness groove to compute the wheel diameter and its circumference.

That is why an index, called Witness Groove Index(WGI) is provided with LazerView as an option to enable the user to determine the position of the witness groove on locomotive wheels. Following figure shows a picture of this index.
