7-6-2. Externally Specified Period Hold
(Peak, Valley , Peak-to-Peak and Mean Value)
By this method, the hold detection period is externally specified by the H/M signal to
maintain the hold value until the reset signal is turned on.
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 H/M signal is turned off and
the instant when the T/H signal is turned on.
(Example) Period Specified Peak Hold
t1
:
A delay time between the instant when the H/M signal is inputted and the instant
when the value to be held is detected
1.0ms (max.)
t2
:
A delay time between the instant when the H/M signal is released and the instant
when the value to be held is determined
1.08ms (max.)
t3
