4.8 Extended measuring function (MEASA, MEAWA, MEAC) (option)
Comments
; Measuring in mode 2 with active measuring
system. Wait for measuring signal in the
sequence rising edge probe 1, falling edge
probe 1, rising edge probe 2, falling edge
probe 2 while traversing path to X=100.
; Preprocessing stop
; Check that the measurement with probe 1 is
successful.
; Save measured value acquired on first
programmed trigger event (rising edge probe 1).
; Save measured value acquired on second
programmed trigger event (rising edge probe 1).
; Check that the measurement with probe 2 is
successful.
; Save measured value acquired on third
programmed trigger event (rising edge probe 2).
; Save measured value acquired on fourth
programmed trigger event (rising edge probe 2).
