Description
Enter the trigger for the start of sampling in "TIMING input" for the 32-pole
terminal block.
The period that the signal input to "TIMING input" is ON is the sampling period.
The measurement values actually sampled vary according to the TIMING
input mode setting.
ON
Timing input
OFF
Important
When a delay time is set, input OFF and sampling period end are not
synchronized. End timing is after the specified sampling period has elapsed.
The period in which the measured value exceeds the preset self-trigger level
is taken to be the sampling period.
Hold measurement can be performed without a synchronous input.

When a delay time is set, the timing that the measured value falls
below the self-trigger level and the sampling period end are not
synchronized. End timing is after the sampling period has elapsed.
The period in which the measured value falls below the preset self-trigger
level is taken to be the sampling period.

When the delay time is set, the timing when the measurement
value becomes invalid value and when the sampling period is
finished are not synchronized.
Timing when the Setting Valid value finishes is after the sampling
period passed.
