DISTO D8 on the Leica Tri100 tripod for stability and ease of measuring using the TA360 or LSA360 adaptor bracket The adaptor bracket ensures the measurement point the back of the DISTO is always in the same position e Position the D8 amp tripod in front of the building with the slope of the roof coming down towards you e With the D8 at 90 to the building switch on the unit and select the roof slope measurement function press the key directly below the 2nd key 4 times the roof slope function symbol will appear directly above the DISTO symbol on the left hand side of the screen e The first measurement is to the ridge of the roof e Use the digital viewfinder one press on the key positioned to the left of the On Dist key and align the cross hairs on the viewer to the desired measurement point on the ridge e Use the zoom function by pressing the viewfinder key to get 2 times or 4 times magnification ensuring the measurement point is accurately targeted e Press the On Dist key to take the measurement or to maintain stability use the Timer key to initiate the measurement process waiting until the bleep confirms completion of the measurement e Rotate the D8 downwards keeping in a vertical plane again using the digital viewfinder to accurately target the lower edge of the roof e Press the On Dist key or again use the Timer key to take the second measurement The DISTO
