Adjustment:
When switching on the instrument a recognition of the sensor is given. All sensor parameters will be loaded into the electronics and the instrument will run without a new
adjustment. If the sensor type has been changed (e.g. FMU40 against FMU42) the error code E521 appears on the display after switching on. In this case a reset has to be made.
Input the code "333" in level "diagnostics" (matrix field V9H3). The instrument is now ready for operation.
