Preparatory steps

Reset to factory settings
NOTICE
A reset may negatively impact the measurement.
‣
Perform a new basic setup after resetting the device.
Using the reset function
It is always advisable to reset the device if you want to use a device with an unknown
history.
Effects of a reset
• All the parameters are reset to the factory setting.
• Linearization is disabled. If a linearization table is present it is not deleted, however, and
can be reactivated if necessary.
• Interference echo suppression (mapping) is disabled. The mapping curve is not deleted,
however, and can be reactivated if necessary.
Effect on a 5-point linearization protocol
With the creation of a 5-point linearity protocol, the measuring system (FDU9x sensor and
FMU9x transmitter) is adjusted and the measuring accuracy is optimized for the specified
range.
The
Zero distance
service parameter is fine-adjusted for this adjustment. Following a
reset, this parameter must be re-configured in the Service menu according to the data
indicated on the 5-point linearity protocol for the FDU9x sensor. Please contact Endress
+Hauser customer service for this purpose.
Performing a reset
1. Navigate to
Device properties → Password/reset → Reset
.
2. Enter "33333".
