Typical Tilt Current Meter Settings
The “brains” of the tilt current meter is the MAT
-1 data logger. The MAT-
1 has the ability to use a “
burst
mode” recording interval (see below). This figure highlights the three “burst mode” parameters that are
saved to the MAT.cfg file and are used to configure the TCM for a wide range of environments.
Burst Logging sets the logger to alternate between rapid sampling and sleep mode. Burst Logging allows
for accurate measurements while conserving battery life. For example, a typical configuration would
have the meter wake up every minute, record at 8 Hz for 20 seconds and then sleep for 40 seconds. The
result of this setup would be 160 samples recorded every minute. After the deployment is complete, the
160 samples will be post processed into 1-minute velocity records. Thus, in this example, each velocity
measurement is an average of 160 samples taken over a 20 second period.
