beam position is automatically recorded and taken as the end point of the
readjustment.
6. Continue measurement as before, rotating the shafts and pressing
take measurements at the available positions.
The program includes the displacement of beam readjustment in its alignment
calculations.
'Laser End' is displayed when the reflected beam fails to strike the detector.
This situation occurs when machines are severely misaligned, or when the
beam travel is long. Measurement is not taken when this message appears.
Averaging
In certain industrial conditions, it may be necessary to increase the number
of measurements to be averaged when taking readings to attain the desired
accuracy. Particular cases include applications with increased machinery
vibration. An increased averaging also improves the accuracy when measuring
sleeve bearings, white metal bearings and journal bearings.
The number of individual readings which are averaged together to form one
measurement are set via the "Measurement options" screen. Press
access the menu. While in the menu screen use the navigation keys to highlight
the 'Measure options' icon and confirm selection by pressing
"Measurement options" screen opens.
