Under ideal conditions the flowmeter will operate continuously with no manual adjustment or
intervention required.
If unstable/wrong measurements occur, it is often due to insufficient/wrong earthing or potential
equalization. If earthing connection is OK, check transmitter as described in Transmitter check
list, and sensor as described in sensor check lists (see the respective operating instructions).
The SITRANS F M Verificator is an external tool developed for verifying the MAG 5000/6000
system, installation, and application. It is a highly advanced instrument, which carries out the
complex verification of the entire flowmeter system according to unique SIEMENS patented
principles. The verification test is automated and the instrument easy to use, so no human error
or influence will affect the verification.

Transmitter check list
When checking SITRANS F M installations for malfunction the easiest method to check the
transmitter is to replace it with another MAG 5000/6000 transmitter with a similar power supply.
A replacement can easily be done as all settings are stored in and downloaded from the
SENSORPROM
®
unit - no extra settings need to be made.
If no spare transmitter is available - then check transmitter according to check table.
