Level (only Peak and Valley)
By this method, the hold detection section is from the point in time when the indicated value
crosses the Hold Start Level until it crosses the Hold Stop Level. The hold is released by turning on
the T/H signal as a reset signal. The H/E output signal is on between the instant when the hold
section time ends and the instant when the T/H signal is turned on.
However, there are limitations that the Hold Start Level should be passed HI and the Hold Stop
level be passed LO in peak hold, while the Hold Start Level should be passed LO and the Hold Stop
level be passed HI in valley hold.

5-12.Multi-hold Function
By this function, up to 16 types of hold, graph and comparison set values can be stored and selected
with external switching signals of WORK0 - WORK3.
Normally, if there is no entry for WORK0 - WORK3, the set value of WORK00 is selected, but when
WORK0 - WORK3 are in the following conditions, the set value of each
Measurement work is selected.
(0: open, 1: short)
