46 Configuration Parameters
Alarm Parameters The Alarm parameters control the operation of the alarms (alert and danger
level) and provide alarm status. The XM-360 provides a total of 12 alarms.
Each alarm is permanently associated with a corresponding measurement (for
example, Channel 1 Value alarm, Channel 2 Rate Alarm, and so on). Use the
parameters to configure which measurement the alarm is associated with, as
well as the behavior of the alarm.
Measurement Time Constant The time constant used for smoothing (low-pass
filtering) of the measurement value.
Note: The greater the measurement
time constant, the slower the
response of the measured value to
change in the input signal (less
sensitive to noise in the signal).
Rate Time Constant The time constant used for smoothing (low-pass
filtering) of the rate value. Seconds
Note: The greater the rate time
constant, the slower the response of
the measured rate of change in the
input signal (less sensitive to noise in
the signal).
