Peak hold (Trigger mode: One shot)
While the external trigger input is OFF, the peak value is constantly updated, but this is an internal process
and it does not appear on the display or as the judgment output.
When the external trigger input is turned ON (at a rising edge), the internally updated peak value becomes the
new hold value.
Note
An indefinite state is held during the following intervals:
From the time immediately after the power is turned ON until the external trigger is turned ON.
From the time the reset input is turned ON until the external trigger is turned ON.
In this type of sample 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.)

Operation procedure
Operation is the same as for the sample hold type in the preceding section.
Select the appropriate measurement mode (MEAS) from P-H, B-H, P-P, and P-P/2.
