Note:
‹
The sampling rate of the recorder is fixed at 200 milli seconds by the hardware, i.e.
samples 5 measured data per second.. If the logging speed is set at 1 second in
Instant mode, the recorder logs using the last of five measured data values. For
the same speed in Averaging mode, the recorder logs using the average of the five
measured data values. For the same speed in the Maximum or Minimum mode,
then the recorder logs using the maximum or minimum of the five measured data
values..
