Endress+Hauser Micropilot FMR51 - 5 Point Linearity Protocol

Micropilot FMR51, FMR52
98 Endress+Hauser
5-point linearity protocol
The following notes must be taken into account if option F4 ("5 point linearity protocol") has
been selected in feature 550 ("Calibration").
The five points of the linearity protocol are evenly distributetd across the measuring range (0% to
100%). In order to define the measuring range, Empty calibration (E) and Full calibration (F) have
to be specified

.
The following restrictions have to be taken into account when defining E and F:

2) Feature 610 "Accessory Mounted", option OM
3) Feature 610 "Accessory Mounted", option OU or OV
4) This value is independent of the actual size of the antenna extension.
The linearity is checked under reference conditions.
The selected values of Empty calibration and Full calibration are only used to record the
linearity protocol and are reset to their probe specific default values thereafter. If values
different from the default are required, they must be ordered as a customized parametrization
→  99.
12) If E and F are not specified, probe dependent default values will be used instead.
