Unipulse f395 - Updating the Amount of Displacement

13.Waveform Comparison / Waveform and Displacement Comparison Mode
75
The "0" periods are thinned-out periods. The
wider the loss interval, the sharper a change
occurs. In this case, the WARNING signal is
output (turned on) through pin 48 of the
control connector due to a failure of a perfect
comparison with all data. Slow down the
displacement changing speed to prevent the
WARNING signal from being output. The
WARNING signal is cleared when the
START signal is input (turned on).
13-5-3. Updating the Amount of Displacement
If the amount of displacement is not updated for the number of samplings set under
Forced-Termination Limit (See "16-2-15. Forced-termination Limit" P120.), sampling is
terminated forcedly. At this time, HI and LO are also output simultaneously if the
Forced-Termination Output setting (See "16-2-16. Forced-termination Output" P120.) is
"ON".

・ During sampling, displacement values are measured by peak hold.
Therefore, even if the displacement is restored, the measured value of
the peak point of displacement is processed. (Displacement values are
measured by valley hold during return measurements in the Hysteresis /
Hysteresis 2 mode.) When two or more samplings are performed at the
same displacement point, if any measured value is off the High/Low
Limit Waveform, the peak/valley value at that time is recorded (taken
later if off both the high and low limits), and if values are not off the
waveforms, the last measured value is recorded.
・Samplings with 0 or less displacement values are all processed as
displacement=0.
・Occurrence of thinning-out/ WARNING is shown by changing the color of
the displacement measured value display as follows (upper left of the
main screen). (Both return to normal conditions when the START signal
is input.)
Thinning-out ........Yellow
WARNING ..........Red
・ Sampling is terminated when the displacement value exceeds the full
scale value or the STOP signal is input. For the full scale value of
displacement, see the item P.37.
・When HI and LO are output by forced termination, judgment operation is
not performed
