As shown in TABLE
, all output modes give two diagnostic values:
Sonic
Diagnostic Flag
and
Gas Diagnostic Flag
. The values contain a bit field with
each bit representing a monitored condition. When a certain condition is
detected, the corresponding bit is set. The value remains set until the event that
caused the condition is no longer present. TABLE
and TABLE
describe the bits in the sonic diagnostic flag and the gas diagnostic flag,
respectively.
