Cerabar M HART Operation
Endress+Hauser 25
5.2.2 Function of the operating elements
Use the "Zero" and "Span" keys to set the lower-range value and upper-range value of the bar graph
in the display module. These settings do not have any effect on the digital output value (OUT value)
and the "measured value" in the matrix field V0H0.
If the display does not show zero after calibrating the lower-range value at zero operating pressure
(position-dependent), it can be corrected to zero by adopting a bias pressure.
5.3 Operation via Endress+Hauser operating program
5.3.1 FieldCare
FieldCare is an Endress+Hauser asset management tool based on FDT technology. With FieldCare,
you can configure all Endress+Hauser devices as well as devices from other manufacturers that
support the FDT standard.
FieldCare supports the following functions:
• Configuration of transmitters in online operation
• Loading and saving device data (upload/download)
• Documentation of the measuring point
Connection options:
• HART via Commubox FXA195 and the USB interface of a computer
!
Note!
• → See also Page 21, Section 4.3.2 "Connecting Commubox FXA195".
• For more information, see → www.endress.com.
No. Operating element Function
➀ Damping switch Switch position "off": damping 0 s
Switch position "on": damping 2 s
It is possible to enter a damping value between 0 and 40 s via communication,
e.g. with the handheld terminal.
➁ Key for lower-range value The value currently saved for the lower-range value, e.g. 4 mA (zero point), is
displayed and the pressure present is accepted as the lower-range value.
➂ Key for upper-range value The value currently saved for the upper-range value, e.g. 20 mA, is displayed
and the pressure present is accepted as the upper-range value.
➁ + ➂ Bias key combination:
Key for lower-range value and
Key for upper-range value
The value currently saved for the bias pressure is displayed and the pressure
present is accepted as the bias pressure.
➁ + ➂ Reset key combination:
Key for lower-range value and
Key for upper-range value
The reset is triggered if the two keys are pressed and held for at least
7seconds.
