RECOMMENDED <br />LINE MEASUREMENT PROCEDURES <br />When the initial T.V. inspection is done, the following procedures will be followed <br />after setting up on upstream manhole. (Refer to Diagram) <br /> <br />Measure Depth of Manhole: This is done by measuring from the bottom of the <br />invert to the top of the ring. <br /> <br />Center to Center: To obtain, measure from the inside ring of the upstream <br />manhole to the outside ring of the downstream manhole. <br /> <br />Pipe Size: Two measurements will be taken from about 6-10" inside pipe when <br />edges are broken. On lines 8-24", inside calipers will be used. On lines larger <br />than 24", a tape can be used but always get two measurements. These two <br />measurements should be taken from any of the following clock positions: 12-6; <br />9-3; 8-2; 10-4. <br /> <br />Location of Service: You will also already have your KEVLAR tape attached to <br />your camera. As your camera approaches each service, rotate the camera to <br />look exactly at the center of the service and record the KEVLAR tape <br />measurement from an established reference point. Record the camera footage <br />on the front of th T. V. Report and the KEVLAR measurement is on the back of <br />the T. V. Report. <br /> <br />
