capacity is 131,072 lines. Recording a data point every second will give over 36 hours of
recording. If the average is set to one minute using the

the recording time is nearly 3 months. Note that a dual gas system with have half the storage
time available because of twice as many data points.

port. The data can be captured using GasViewOP or Hyperterminal .

erase the data. Data can only be erased using Clear Memory Log .
