Self peak hold (Trigger mode: One shot)
■
After the input value exceeds or falls below the specified self trigger level (depending on the specified self
trigger edge direction), constant updating of the peak value is performed automatically. However, this is an
internal process, and does not appear on the display or as the judgment output.
After the input value falls below or exceeds the specified self trigger level (in accordance with the opposite of
the specified self trigger edge direction), the hold value is updated to the internally updated peak value.

When self peak hold is selected, external trigger input has no effect.
