Activates Load monitoring. The On/Off status
is also indicated on the System check and
Channel setup screens.
Once a fault has occurred, switching off Load
monitoring will also reset the error and error
message.
LM Period
The maximum time it takes the system to detect
a loudspeaker malfunction. The intervals of the
pilot signal are derived from this parameter.
The time can be set in a range from 40 to
1000 sec. in 40 sec. detents.
LM Threshold
Large signal threshold. When the output signal
exceeds this voltage level during the
measurement, the tolerance limits for this
particular measurement are increased in order
to compensate for the reduced accuracy.
zMin
tolerance
Lower limit of the impedance window, which is
set to –20 % by default.
zMax
tolerance
Upper limit of the impedance window, which
is set to +30 % by default.
Dev.: Relative deviation in percent in relation to the
reference values determined during
calibration.
