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.
Note
An indefinite state is held on occurrence of the following:
The power is turned ON
The reset input is ON
A sensor head disconnection error or upthrust error (alarm) is canceled
In this type of self peak hold, the judgment output is the same as the judgment value.
(However, please note that there are some measurement modes for which this is not the case.)
When self peak hold is selected, external trigger input has no effect.

In self bottom hold, the relevant value is held for each measurement mode in a similar manner.
