3-point linearity protocol
The following points must be considered if option F3 (3-point linearity protocol) was selected in
feature 550 ("Calibration").
The 3 points of the linearity protocol are defined as follows:
R
A
500 (19.7)
6000 (236)
1
3
2
A0032642
28
Points of the 3-point linearity protocol; engineering unit: mm (in)
A
Distance from the reference point R to the first measuring point
R
Reference point of measurement
1
First measuring point
2
Second measuring point (in the middle between the first and third measuring point)
3
Third measuring point
Measuring point
Position
1st measuring point
• At a distance A from the reference point
• A = length of a 500 mm (19.7 in)
• Minimum distance: A
min
= 1
000 mm (39.4 in)
2nd measuring point
In the middle between the 1st and 3rd measuring point
3rd measuring point
6
000 mm (236 in) below the reference point R
The position of the measuring points can vary by 1 cm (0.04 in).
The linearity check is performed under reference operating conditions.
