Page 11: Layout
Layout The geodyna optima balancer is fitted with a laser scanner (fig. 8-1, details 1, 2 and 3) for the automatic measurement of the wheel data. The internal laser scanner (detail 1) carries out the following measurements: a) detects the internal profile of the rim to identify the optimum position of the weight to apply on the left part or internal part of the rim;…

Page 12: Balancing
Operational Selections 9.0 Optima BALANCING The geodyna optima balancer is fitted with 3 laser scanners with integrated CCD that guarantee an accurate detection of the characteristics of any type of wheel. The laser scanners carry out a series of geometric measurements on the rim, the tread, the flange and the profile of the rim and of the whole wheel with a single measuring run of a few seconds.

Note: The change in the position of the weight is saved by the machine, then automatically suggested for all subsequent wheels with the same dimensions. The selection is deleted when the machine is switched off. F2: the top part of the key is described in the geodyna 6800 basic model instructions. -

Page 9: Tdi Tread Depth Indication
1.4.2 TDI Tread Depth Indication When run in OPTIMA mode, the machine always automatically detects the depth of the tread groove at the centre of the tire and over its whole circumference. According to the mean value detected and the limit value set, the program displays one of the following Tread Groove indications on screen (Fig.

Page 11: Layout
Layout The geodyna optima balancer is fitted with a laser scanner (fig. 8-1, details 1, 2 and 3) for the automatic measurement of the wheel data. The internal laser scanner (detail 1) carries out the following measurements: a) detects the internal profile of the rim to identify the optimum position of the weight to apply on the left part or internal part of the rim;…
-
Page 12: Balancing
Operational Selections 9.0 Optima BALANCING The geodyna optima balancer is fitted with 3 laser scanners with integrated CCD that guarantee an accurate detection of the characteristics of any type of wheel. The laser scanners carry out a series of geometric measurements on the rim, the tread, the flange and the profile of the rim and of the whole wheel with a single measuring run of a few seconds.

Page 13
Note: The change in the position of the weight is saved by the machine, then automatically suggested for all subsequent wheels with the same dimensions. The selection is deleted when the machine is switched off. F2: the top part of the key is described in the geodyna 6800 basic model instructions. -

Page 15: Optima Entry Screen
9.2 OPTIMA ENTRY Screen (fig. 9.2-0) Press F6 in the balancing screen to access. The control software automatically displays this screen whenever, at the end of the wheel measuring run, the measuring values exceed the preset limits. The overall wheel (rim + tire) measuring run is displayed. To move the cursor on the wheel graph, rotate the wheel by hand in both directions.
