Measure
The following parameters have to be set:
• The distance between the measuring points in the offset axis (positive values only)
• Number of axis along which measurement is to be taken
1 ˆ = abscissa
2 ˆ = ordinate
• Direction of measurement
1 ˆ = Measurement to be taken in positive direction
-1 ˆ = Measurement to be taken in negative direction
Note:
The measurement path "m" along the measuring axis must be smaller than the offset path
R19. Therefore only an angle of max. 44.999° can be measured. However, the measurement
can be taken from every side.
Measuring cycle L978 automatically calculates a measurement path as a function of the offset
path that fulfils this condition. The measurement path S entered in the basic display is only
taken into account if it is greater than the measurement path calculated by the cycle.
When you press the softkey "MEASURE", a selection display appears requesting you to
position the probe between the measuring points on the workpiece.
