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..
Sampling Logging ( historical trend ) Display ( real time )
Instant 200mS the last of 5 measured data the last of 5 measured data
Averaged 200mS the average of 5 measured data the last of 5 measured data
Maximum 200mS the maximum of 5 measured data the last of 5 measured data
Minimum 200mS the minimum of 5 measured data the last of 5 measured data
