Creating a Preset
To customize the temperature, accelerometer/magnetometer, start and stop time settings,
select New Preset from the dropdown menu. Once complete, enter in a description and
select the Save icon so that your new preset can be used again in the future.
5.5
Enabling and Disabling Logging
Channels
The logger’s three sensors can be turned on or off
independently. Check or uncheck the channels as
desired. Disabling a sensor that is not needed for an
application prolongs battery life and results in a
smaller data file. See
“Battery Life” for more
information.
5.6
Recording Rate & Burst Mode
The MAT-1 logger allows the temperature sensor
recording interval to be set independently from the
recording rate of the magnetometer and
accelerometer.
All sensors have a minimum recording rate of one
sample per hour. The magnetometer and
accelerometer sensors may be recorded at up to 64
samples per second (64 Hz). The maximum rate for
the temperature sensor is 1 sample per second (1
Hz).
The magnetometer and accelerometer logging
interval are set by using
the “Burst Interval”
,
“Burst
Rate,
”
and “Burst Duration”
in combination. These
three settings allow the logging interval to be set to
record continuously at some rate (Example A records
at 1 sample per minute, Example B at 16 Hz) or to
utilize non-
continuous “Burst Logging”
(Example C).
When the logger is configured for “Burst Logging” it
records at the “Burst Rate” for the “Burst Duration”
and then it switches to a low-power sleep mode for
the
remainder of the “Burst Interval”.
The process
repeats until the logger is stopped. “Burst Logging”
conserves battery life and reduces the size of the
data file.
Example A: 1-minute logging interval (1 sample
per minute).
Example B: Continuous logging at 16 Hz (960
samples per minute).
Example C: Intermittent logging with a 10 second
“burst” at 16 Hz with 50 seconds of sleep per
minute (160 samples per minute).
