In the above example, Multipoint measurement has been selected. The quality of the measurement
may be displayed either as a measurement standard deviation
1
(SD) or measurement quality
2
factor. The averaging is set by tapping the 'Averaging' button.
Averaging
In certain industrial conditions, it may be necessary to increase the number of measurements (recorded
laser pulses) to be averaged when taking readings to attain the desired accuracy. Particular cases
include environments with increased machinery vibration. An increased averaging also improves the
accuracy when measuring sleeve bearings, white metal bearings and journal bearings.
Averaging is possible in ‘point’ measurements such as ‘Multipoint’ and ‘Static mode’.
Set the averaging by tapping the 'Averaging' button [1]. A scale [2] used to set the averaging value
appears on the screen. Tap desired averaging value which then appears in the 'Averaging' button [1].
1
Standard deviation describes how closely a group of datra points are clustered around the average of
those data points. The smaller the standard deviation, the better the quality of the data collected.
2
displays quality of measurement based on following measurement and environmental factors:
rotataion angle, ellipse standard deviation, environmental vibration, rotation evenness, angle rotation
inertia, rotation direction, rotational speed and filter output
