"-----" is displayed until the first measurement result is displayed.
Reference For details of the upper/lower limit value entry method, refer to section "3.2
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.

3.4.4 Rotation/Eccentricity Detection Mode: "

Use this mode to detect eccentricity in the rotation of a shaft. The minimum
point in the deviation of measurements of a rotating body is defined as a
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.
・Holding measurement mode is fixed at peak-to-peak hold.
・The trigger condition is set with a trigger hysteresis.
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.
Example of detection of eccentricity
1) Mount the sensor head on equipment.
Prepare the sensor head mounting fitting and the object to be detected.
Reference For mounting of the sensor head, refer to section "1.6.2 Mounting the
Sensor Head" on page 17.
2) Adjust the sensor head and the position of the object to be detected.
1. Select the material according to the object to be detected.
Reference Refer to section "4.1 Selection of Object to Be Detected" on page 70 for
selection of the material.
If the object to be detected is iron, select "FE". The factory shipment setting of
GP-X series is stainless steel (SUS304).
