13.Waveform Comparison / Waveform and Displacement Comparison Mode

13-5. Waveform and Displacement Comparison Mode

In this mode, High/Low Limit Comparisons are made with waveforms changing with
displacement. The operation is the same as in the Waveform Comparison mode.
However, since the X-axis is not a factor of time but input from a displacement sensor,
there are restrictions as follows:

13-5-1. Scale of the X-axis

The full scale of the X-axis is determined by the displacement value (mm, etc.) input by
Equivalent Input Calibration or Actual Load Calibration. (See the
greater than the above cannot be displayed. The internal resolution is approx. 1/2000.
Also, displacement input values are automatically digital-zeroed with a sampling start
under CAL. Protect when the Level Axis Select setting (See "16-2-9. Level Axis Select
/ Waveform Start Level / Waveform Termination Level / Hold Start Level" P113) is "Y-
axis". (See "6-4. Digital Zero" P39.)

13-5-2. Handling of Sudden Changes

In the case of sudden changes (9 counts or more) in the amount of displacement in the
one-time sampling interval, High/Low Limit comparisons are not made each time.
Comparisons are madeas they are thinned out in accordance with a specified rule.
As a result, the waveform may be displayed as follows:
