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, depending on the selected probe:
R
A
C
B
LN
1
3
2
A0021090
A Distance from the reference point R to the first measuring point
B Measuring range
C Distance from the probe end to the third measuring point
LN Probe length
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
Position of 1st measuring point A =350 mm (13.8 in)
Position of 2nd measuring point In the middle between the 1st and 3rd measuring point
Position of 3rd measuring point C = 250 mm (9.84 in)
Minimum measuring range B ≥ 400 mm (15.7 in)
Minimum probe length LN ≥ 1 000 mm (39.4 in)
The position of the measuring points can vary by ±1 cm (±0.04 in).
The linearity check is performed with the entire device and under reference operating
conditions.
