Data logging mode can be started or stopped via ‘Key 6 - Logging’ accessed from the
‘Utilities’ menu. Press ‘Key 4 – Start/Stop Logging’ to start and stop data logging.
Whilst in data logging mode the instrument will automatically record data at the preset
intervals, including running the pump for a preset time.
Active logging mode is indicated on the ‘Main Read Screen’ by the icon.
The operator is able to edit the default ID, pump run-time interval, set IDs and start/stop
logging.

Select the desired option by pressing ‘Keys 1 to 4’. Then enter the appropriate
setting using the keypad followed by the ‘Enter’ key.
1-Every 00 mins.
- Press ‘Key 1’ to enter the time in minutes for the time
frame between sample readings. The interval controls the
reading frequency in minutes, i.e. every ten 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
ten seconds if it takes 30 seconds to draw in a new
sample.
3-ID Set ID
- Press ‘Key 3’ to create eight digit alpha-numeric ‘Site’ and
‘ID’ identifiers.
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.
