E Sensor side
8. Calculate the offset value according to the following formula:
For left-side arm:
(L2 - L1) ÷ 2 = offset value
For right-side arm:
(L1 - L2) ÷ 2 = offset value
9. Use the arrow keys (C) in selection field 1 to select an offset value.
The offset value may have a positive or negative sign.
For left-side arm:
A positive offset value shifts the sensor in room direction.
A negative offset value shifts the sensor in wall direction.
For right-side arm:
A positive offset value shifts the sensor in wall direction.
A negative offset value shifts the sensor in room direction.
Since the offset value can be set only in steps of 500 (500 = 0.5 mm),
set a value that is as close as possible to your calculated value.
10. Save the setting [ → 251].
11. Touch the T key (A).
The test mode is deactivated again.
The offset settings are taken into account in normal operation.
12. Move the sensor to its reference position by touching the R key (B).
The sensor can always be moved back and forth between its front
and center positions with the R key.
13. Measure distances L1 and L2 with a slide gage and calculate the
remaining offset as described.
If the offset is still > ± 0.5 mm, the offset value must be corrected
again. To do so, repeat this service routine.
If the offset is < ± 0.5 mm, the calibration is OK.
14. Exit the service routine [ → 252].
15. Reattach the cover to the cephalometer [ → 37].
