Commissioning Prosonic M - FOUNDATION Fieldbus
42 Endress+Hauser
6.3 Resetting the device
It is advisable to reset the device parameters before the commissioning if you want to use a device
with an unknown history.
!
Note!
5-point linearity protocol
The specified measuring accuracy is a typical value ä 79, "Performance characteristics".
With the production of the 5-point linearity protocol the measuring system (sensor and electronic)
is adjusted exactly to one another and the measuring accuracy is optimized for the specified range.
To realize this, the parameter "zero distance" is fine adjusted. After a reset the value for the zero
distance has to be re-parameterized in the service menu according to the data on the associated 5-
point linearity protocol. Please contact the Endress+Hauser service.

"
Caution!
A reset may lead to impairment of the measurement. As a rule, a basic calibration is required after
a reset.

Note!
The default values of each parameter are shown in bold in the menu overview in the appendix.
In order to carry out the reset, enter the number "33333" in the "reset" (0A3) function in the
