programmed sequence)

N100 MEASA[X]=(2,1,-1,2,-2) G01 X100 F100 ; 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.
N110 STOPRE ; Preprocessing stop
N120 IF $AC_MEA[1]==FALSE GOTOF PROBE2 ; Check that the measurement with probe 1 is
successful.
N130 R10=$AA_MM1[X] ; Save measured value acquired on first
programmed trigger event (rising edge probe 1).
N140 R11=$AA_MM2[X] ; Save measured value acquired on second
programmed trigger event (rising edge probe 1).
N150 PROBE2:
N160 IF $AC_MEA[2]==FALSE GOTOF END ; Check that the measurement with probe 2 is
successful.
N170 R12=$AA_MM3[X] ; Save measured value acquired on third
programmed trigger event (rising edge probe 2).
N180 R13=$AA_MM4[X] ; Save measured value acquired on fourth
programmed trigger event (rising edge probe 2).
