MULTICAL® 803 & ULTRAFLOW®
8 Info code
MULTICAL® constantly monitors a number of important functions. If a serious error occurs in the
measuring system or installation, a flashing “INFO” appears in the display. The “INFO” field keeps
flashing as long as the error is present, no matter which reading you choose. The “INFO” field
automatically switches off when the error has been corrected. For indicating current errors in
MULTICAL®, it is possible to scroll to the information code in the display. This is the display in which
”INFO” does not flash, but is shown permanently. The information code display is available both in
the USER loop and TECH loop. The info code consists of 8 digits, and each functionality has its own
digit dedicated to the indication of relevant information. For example, all information concerning
temperature sensor t1 is shown in the display as the second digit from the left.
