Certain loggers have an
Averaging
function
.
Averaging may be enabled by
checking the
Enable averaging
box in the
Date and time picker
window. If
averaging is selected, the user must choose an averaging period that is less than
the sampling period.
When averaging, the XR-420 and XR-620
loggers take samples at a rate of 6Hz over the
averaging period and records the average.
Thus, if the user specifies 5 seconds of
averaging, 5 seconds of 6Hz samples are taken
(30 samples), and averaged into one reading. The TGR-1050HT and TGR-2050
loggers take samples at 4Hz. The TWR-2050 and TWR-2050HT loggers collect
samples at the rate set in the configuration window specific to these loggers
(p.17). All channels are independently averaged. The operating software will
cross check the averaging settings with the time taken to read the samples and
with the defined sampling rate. Any inconsistencies will be indicated to the user.
Note
: This is not to be confused
with the pure 6Hz sampling of
the XR-620 series loggers.
