8.8.1 Different kinds of messages
a) Pointers (operating conditions) during measurement provided by 6 markers in the 3rd (bottom)
line of the display, see Sect. 8.8.2.
b) Application errors, indicating an application error condition in which no valid measured values
are currently established. By changing the tank conditions (e.g. filling) this error can usually be
remedied, see "Error list" in Sect. 8.8.3.
c) Minor errors, indicating the failure of functions that usually do not affect measurement, see
"Error List" in Sect. 8.8.3.
d) Correctable errors, which can be remedied by operator action (manual) at the BM 70 M, or
possibly by KROHNE Service, see "Error List" in Sect. 8.8.3.
e) FATAL ERROR renders operation of the BM 70 M impossible; occurs only when the device is
switched on (powered) or after special test functions have been executed, when the self-test
identifies an error in the electronics of the BM 70 M, see "Error List" in Sect. 8.8.3.
