Figure 5-37 Status messages
With this function, you can parameterize the status message display in the status line of the
measured value display. You can display a maximum of four different status messages. The
message CODE ■/□ provides information on the current operating mode
("Coded"/"Decoded") and is therefore always displayed.
The device activates the functional check (softkey 5 on the function screen) when it
determines that the measured value was influenced.
This is the case:
● During the warm-up phase
● After entry of the code (i.e. change to "Operator control mode")
● During automatic calibration (Autocal) or remote calibration
Note
Functional check ("CTRL")
If the functional check is active, the measured value might be falsified! The measured
value must therefore be checked when the functional check is no longer active.
As long as you are in code level 1 or 2, in "Operator control mode" in other words, the
functional check is active. If you parameterized the analog output with "Memory on" using
function 77, this remains in the fault current until you leave the corresponding code level,
and therefore "Operator control mode", and return to "Coded display mode" (press
[MEAS] twice).
