Rotation/Eccentricity Detection Mode - Panasonic GP-X Series User Manual

6) Press the

3.4.4 Rotation/Eccentricity Detection Mode: "

Use this mode to detect eccentricity in the rotation of a shaft. The minimum
reference trigger and the peak-to-peak distance is measured in the sampling
period to output judgment in comparison with the preset upper and lower
limit values.
After the rotation/eccentricity detection mode is selected, the following
measuring conditions are set.
The internal trigger level, trigger edge direction, trigger delay and sampling
time are ignored.
Comparison with previous mean is invalid.
To use the external trigger, internal trigger with a trigger level, or cyclic
trigger, select the manual mode and enter settings.
1) Mount the sensor head on equipment.
2) Adjust the sensor head and the position of the object to be detected.

For details of the upper/lower limit value entry method, refer to section "3.2
Reference
Upper and Lower Limit Value Settings" on page 48.
For the detection action, refer to the example of the internal trigger mode
with zero sampling time described on page 41.
Enter settings so that the internal trigger level and the sum of the internal
trigger level and trigger hysteresis become within 110% and within 120% of
the maximum detection distance, respectively.
