13.Waveform Comparison / Waveform and Displacement Comparison Mode
78
13-7. Hold Operation
In the Waveform Comparison / Waveform and Displacement Comparison mode, any one
of hold operations: sample hold, peak hold, and valley hold can be executed
simultaneously. Simultaneously with the Waveform Comparison Judgment, a High/Low
Limit Judgment can also be made with the hold point.
13-7-1. Operation and Operating Method
Example:
When peak hold is executed
A High/Low Limit Judgment is made with the hold point only when the
HI-HI/LO-LO Mode setting (See "16-2-7. High Limit / Low Limit / HI-HI/
LO-LO Mode / HI-HI Limit / LO-LO Limit" P109.) is "Hold". (If the setting
is "Sampling Value", real-time judgments on the sampling value will
result.)
