Eccentricity/Vibration Measurement Setting Methods
Setting methods when performing eccentricity/vibration measurements are as follows.
This section provides application setup examples.
Preparation and Overview
When measuring eccentricity/vibration for flat or
cylindrical workpieces, the “Peak-to-peak function” of
the LK-G Series is used.
The peak-to-peak function automatically calculates the difference between MAX and MIN value for a custom sampling
cycle. The custom sampling cycle can be controlled using the timing input or by RS-232C commands.
The target is rotated, time input is turned ON, and sampling is started. When the timing input is turned ON once
again, sampling ends and the maximum variation in the measurement value is displayed, making it possible to obtain
comparator output.
