1-Every 00 mins.
- Press ‘Key 1’ to enter the time in minutes for the
timeframe between sample readings. The interval
controls the reading frequency in minutes, i.e. every 10
minutes.
2-Pump 00 secs.
- Press ‘Key 2’ to enter the time in seconds for the length
of time you wish the pump to run when taking a sample
reading. The pump run-time is the time in seconds for
which the pump runs prior to the reading being stored.
This figure will also need to take into account the length
of sample tube and the volume of the sample gas. For
example, there is little point setting a pump run-time of
10 seconds if it takes 30 seconds to draw in a new
sample.

- Press ‘Key 3’ to create an 8-digit numeric ID Code.
4-Start/Stop Logging - Press ‘Key 4’ to start and stop data logging.
Note: Data logging mode is automatically stopped when the instrument is
switched off or if the logging parameters are edited.
