Note1) When the analog input values exceed the upper and lower limits of the input range, the digital values maintain
the upper and lower limit values.
(Note 2) Because of 12-bit resolution, the higher 4 bits of digital conversion value are always zero.
(Note 3) The time shown in the figure below is required to reflect analog input values in the input device area (WX)
read by the CPU unit.
(Note 4) Averaging is not processed within the cassettes. Perform averaging with programs as necessary.
