DETAILED SETTINGS
Setting the Trigger for Measurement in Hold Mode
Select the input method for the timing of the start and end of the measurement period.
Hysteresis (hysteresis width)
Set the hysteresis based on the fluctuations in the measured values around the trigger level. The
hysteresis will be applied from the start of the sampling period and will prevent timing input chatter-
ing.
Selection Details
TIMIG
(Timing input)
(Default)
Enter the trigger for the start of sampling by using the timing input. The period
that the timing signal is ON is the sampling period.
When a delay time is set, the input OFF timing and the end of the sam-
pling period will not be synchronous. Sampling will end after the speci-
fied sampling period has expired.
UP
(Self-up trigger)
The sampling period is the period that the measured value is greater than the
specified self-trigger level. Hold measurement is possible without a sync input.
When a delay time is set, the timing when the measured value becomes
smaller than the self-trigger level and the end of the sampling period will
not be synchronous. Sampling will end after the specified sampling
period has expired.
DOWN
(Self-down trigger)
The sampling period is the period that the measured value is lower than the
specified self-trigger level. Hold measurement is possible without a sync input.
When a delay time is set, the timing when the measured value becomes
greater than the self-trigger level and the end of the sampling period will
not be synchronous.
