Data log

Use this area to set the interval between readings. The minimum time permitted is one
second. Users can either select:
•
Single: a data point is taken at the required sampling frequency, e.g. one live data point
every 10 seconds
•
Average: the average value of the data points recorded over the selected time frequency,
e.g. the average concentration between readings
•
Maximum: the maximum concentration between readings, taken over the selected time
frequency
Cub can also be configured to start data logging once concentration levels reach a pre-defined level.
Data logging will stop once values drop below this concentration. Recorded data will be displayed as
one data session until the device is restarted. The exported csv file will also detail how many times
the device reading exceeds the data log trigger level.
Important note: Once the Cub memory has been completely filled, the oldest
data will automatically be over-written with new data logs. The data will be
reassembled as one complete data set, starting at the oldest available data points.
