5-point linearity protocol
The following points must be considered if option F4 (5-point linearity protocol) was selected in
feature 550 ("Calibration").
The 5 points of the linearity protocol are evenly distributed over the measuring range (0% - 100%).
Empty calibration (E) and Full calibration (F) must be specified in order to define the measuring
range

The following restrictions must be considered when selecting E and F:
R
A
C
B F
E
A0015167
A Distance from the reference point R to the 100% mark
B Measuring range
C Distance from the probe end to the 0% mark
E Empty calibration
F Full calibration
R Reference point of measurement

Maximum value for
"Empty calibration"
Rod (non-separable) C ≥ 100 mm (4 in) E ≤ 3.9 m (12.8 ft)
Rod (separable) C ≥ 100 mm (4 in) E ≤ 5.9 m (19.4 ft)
The linearity check is performed with the entire device and under reference operating
conditions.
The selected values for Empty calibration and Full calibration are only used to create the
linearity protocol. Afterwards, the values are reset to the default values specific for the probe. If
values other than the default values are required, they must be ordered as a customized
parameterization →  82.
2) If (E) and (F) are not specified, probe-dependent default values will be used instead.
