11. Hysteresis Mode

11-1. Function

In the Hysteresis mode, go and return waveforms changing with displacement are
sampled, and necessary points in the waveforms are detected to make judgments such as
High/Low Limit Comparisons.
The maximum sampling rate is 2kHz. The operation is almost the same as in the Multi-
Hold mode except for displacement on the X-axis, go and return samplings, and the
maximum sampling rate of 2kHz.

11-2. Setting and Operating Method

1. Make settings as in "10-2. Setting and Operating Method" P47, and
2. Retrieval of a return sampling is as follows
3. The scale of the X-axis and handling of sudden changes in displacement input are the
4. Go and return waveforms are displayed on the graph in blue and red, respectively.
"16-2-14. Hysteresis Interval" P119.
Sampling waveforms are shown by the solid lines. The hysteresis return
output is turned ON when the return waveform sampling starts, and is turned
OFF upon its completion. (See "4-3-2. Input and Output Signals" P25.
same as those in the Waveform and Displacement Comparison mode. (See "13-5.
Waveform and Displacement Comparison Mode" P74.)
If the operation ch is switched and any hold point occurs in
the hysteresis return retrieval period (*), no "+" mark is
displayed when the waveform is displayed.
