Comment
; Check that the measurement was success-
ful.
; Save measured value acquired at the
first programmed trigger event (positive
edge).
; Save measured value acquired at the sec-
ond programmed trigger event (negative
edge).
Comment
; Measuring in mode 1 with both measuring
systems. Wait for measuring signal with
positive/negative edge from probe 1 for
travel path to X=100.
; Check that the measurement was success-
ful.
; Save measured value of measuring system
1 at positive edge.
; Save measured value of measuring system
2 at positive edge.
; Save measured value of measuring system
1 at negative edge.
; Save measured value of measuring system
2 at negative edge.
Comment
; Measuring in mode 2 with active measur-
ing system. Wait for measuring signal in
the sequence positive edge probe 1, nega-
tive edge probe 1, positive edge probe 2,
negative edge probe 2 while traversing
path to X=100.
; Check that the measurement with probe 1
is successful.
; Save measured value acquired at the
first programmed trigger event (positive
edge of probe 1).
