Extend Measurement Range Manually - Fluke 831 User Manual

Extend measurement range manually

Measurement range may be extended manually in both Active Clock and Static measurement
modes. This range extension allows the adjustment of the laser beam such that it does not
miss the detector surface when shafts with gross misalignment or angular misalignment over
large distances are measured. During measurement, manual extension is prompted when the
XY view is accessed before 'Laser End' is displayed.
If the laser dot (1)on the display continues to move further away from the center of the
l
detector screen while shafts are rotated for measurements, tap the detector area (2) to
open the "XY view" screen.
With the "XY view" open, use the yellow horizontal angle adjustment knob and the ver-
l
tical position adjustment thumbwheel to adjust the laser dot such that it is positioned
inside or very close to the square target.
Note
Do not adjust the sensor during the laser adjustment procedure.
