If the "Value Valid = Off" status is present, it means the same as an aster-
isk (*) in the display or in the MSET status display, and the system is outside
the specified measuring range in accordance with the "Technical
data" [►Section 13, Page 90] chapter. The following applies to the transmit-
ted measured value:
▪ During the first measurement after the running-in phase, the value of the
lower detection limit is transmitted.
▪ If measured values within the specified measuring range have already
been recorded, then the last valid measured value is transmitted.
If the status changes to "Value Valid = On", then the system is back in the
valid measuring range.
