5-point linearity protocol
The following must be taken into account if option "5 point linearity protocol" has been selected:
• The five points of the linearity protocol are evenly distributed 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.
3)
• The following restrictions have to be taken into account when defining E and F:
A0019526
Note!
• The linearity is checked under reference conditions.
• The 5-point linearity protocol is always carried out for the complete measuring system (consisting of the
sensor FDU9x and transmitter FMU9x) and it is valid for this combination. It must be defined, at which
sensor channel the sensor is to be tested. There are up to 2 channels for FMU90 and up to 10 channels for
FMU95.
• For details see the technical information TI00397F/00/EN or TI00398F/00/EN.
Scope of delivery
• Instrument according to the version ordered
• This Technical Information TI00396F/00/EN (serves as installation and operating instruction)
• For certified instrument versions: Safety Instructions (XA) or Control Drawings (ZD)
• For FDU90/91 with sensor heater: terminal module, to be mounted in the field housing of the transmitter
FMU90
• For FDU90/91/92 with G 1" process connection: counter nut (PA6.6) + seal (EPDM)
• For FDU93/95/96 with Ex-certificate: process seal (VMQ)

If the values for the full calibration and empty calibration are missing or outside the specified area, the devices are tested with the maximum value according
to the table.
