Digisewer Calibration and Use

To Calibrate Digisewer:

1. Click on the red circle underneath the camera, next to the video feed on the right side.
2. Set the inner pipe diameter and the camera height. Diameter will be the size of the pipe, and camera height will be how high the camera is off the ground.
3. The cross needs to be as centered on the pipe as possible. You can use the blue arrow buttons on the left side to move this.
4. The buttons with the yellow circle on them will make the outer yellow circle wider/thinner, or taller/shorter
   This circle needs to be on the outside black edge of the picture.
5. The buttons with the red circle on them will do the same to the red circle as the yellow circle, making it wider/thinner, or taller/shorter.
   When using a joint to calibrate the red circle, this circle will need to be on top of the joint, so as a view of the joint can be seen on the right hand image.
6. You will need to continue to resize the circles until the joint on the right-hand side is in as straight of a line as possible.
7. Once Digisewer is calibrated, you can save the settings under a specific name (e.g. 8 inch, 10 inch, 15 inch, etc.) to identify what pipe that calibration is intended to be used for.

Digisewer Use:

1. Make sure your lights are at an appropriate brightness by using your controller. Once the lighting is correct you can use the contrast/saturation buttons in Digisewer to further adjust picture quality.
2. To start scanning, click on the red dot underneath the speedometer. It will turn a brighter red and a sliver of an image will appear in the black space beneath. Now you can start driving your crawler.
3. Once you are done you can click the stop button next to the record button, then click the check-mark in the bottom right. This will load the scan into VX.

Be sure that you do not go above 6m/min on the speedometer or it will distort the image. For best image results, keep the speed between 3 and 6.
