MULTICAL® 403
5 Information codes ”INFO”
MULTICAL® 403 constantly monitors a number of important functions. If a serious error occurs in
the measuring system or the installation, a flashing “INFO” will appear in the display. The ”INFO”-
field keeps flashing as long as the error is present no matter which reading you choose. The
”INFO”-field is automatically switched off when the error has been corrected. The info code can be
displayed in in TECH loop reading 2-017-00, for indication of current errors in MULTICAL® 403. The
info code consists of 8 digits and each functionality has its own digit dedicated to the indication
of relevant information. For instance all information concerning temperature sensor t1 is shown in
the display as the second digit from the left.
