MULTICAL® 603
7 Information code
MULTICAL® constantly monitors a number of important
functions. If errors occur 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 instance all information
concerning temperature sensor t1 is shown in the display as the
second digit from the left.
