Monitoring Operations
•
adc-command module mass-centre
Perform a centring operation on the sensor's masses. This sub-command
takes no options.
•
adc-command module mass-lock
Lock the masses for transportation. This sub-command takes no options.
•
adc-command module mass-unlock
Unlock the masses for deployment. This sub-command takes no options.
•
adc-command module calib-sine arguments
Perform a sine-wave calibration according to the specified arguments,
which are given as a space-separated list of key=value pairs:
•
component=[ ALL | Z | N/S | E/W ] - specify the
component(s) to be calibrated
•
duration=m - specify the duration, in minutes, where m is an integer
value. For accurate results, the duration should be significantly longer
than the response time of the instrument.
•
amplitude=a - specify the amplitude, where a is the integer
percentage of the full output of the calibration signal generator. This
can normally be given as 100 but should be reduced if clipping is
noticed.
•
freq=n - specify the frequency (in integer Hertz) or period (in integer
seconds) of the calibration signal, according to the setting of...
•
freq_or_period=[ Hz | sec ] - specifies whether the value
associated with freq is interpreted as Hertz or seconds.
•
adc-command module calib-step arguments
Perform a step calibration according to the specified arguments, which
are given as a space-separated list of key=value pairs:
•
component=[ ALL | Z | N/S | E/W ] - specify the
component(s) to be calibrated
•
duration=m - specify the duration, in minutes, where m is an integer
value. The calibration signal will first go negative for this duration,
then back to zero for the same duration, then go positive for this
duration, then return to zero again for the same duration. For
accurate results, the duration should be significantly longer than the
response time of the instrument.
•
amplitude=a - specify the amplitude, where a is the integer
percentage of the full output of the calibration signal generator. This
can normally be given as 100 but should be reduced if clipping is
noticed.
