7-5-6. Inflection Point Hold
Detection starts when the indicated value crosses the auto start level with the H/M signal
inputted. Detection is performed as long as the H/M signal is 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 hold starts and the instant when
the T/H signal is turned on.
If the auto start level is not needed as a starting condition of the detection period, set
99999.
