6 MAINTENANCE AND TROUBLESHOOTING
Although transmitters SST5X do not require a maintenance on periodical basis, it is good
practice to regularly check the general transmitter status, the possible presence of rust or
damage on the case or on the measuring diaphragm and the presence of clogging in the process
connection.
