7 EXPLANATION OF HOLD FUNCTIONS
7-4.
Auto reset function
It is factory-set that each hold is automatically reset at the start of the detection section, and
therefore, simple control can be performed by one signal without releasing the hold.
Example) Auto reset in externally specified section peak hold
SECTION
However, when the auto reset functions, if the signal causes chattering, the point that should be
taken originally may deviate. Switching is provided so as to prevent the next detection from being
performed until the T/H signal is turned on even if the SECTION signal is turned on again.

0：OFF
After a hold is fixed, the next detection is not started until the T/H
signal is turned on even if the SECTION signal is turned on.
1：ON
After a hold is fixed, the next detection is started when the SECTION
signal is turned on again even if the T/H signal is not turned on. This is
the initial setting (factory default setting).

If the SECTION signal
chatters, the point shifts
from the proper one.
When auto reset is off in externally

The first hold value is
maintained until T/H is
inputted.
Control can be performed without inputting the T/H
signal.
However, a hold value is maintained until the
SECTION signal turns ON.
