G100 Range Optional Products and Accessories
Optional Products
The G100 Analyser range has a number of optional products for purchase which enhance the usability
and enable further analysis of data and reading information.
G100 Range – Download Software (Optional)
The G100 Range – Download Software enables the user to maximise the operation of the incubator
analyser. Instrument readings and event log data may be downloaded to a PC for further analysis and
exported to other applications such as MS Excel. It enables direct communication with the unit,
features a simple download facility and is fully compatible with the latest Microsoft operating systems.
Event Log
The G100 instruments incorporate the facility to log significant events via the ‘Event Log’. This can be
used as an aid to monitoring the use of the instrument. It can also be used as a diagnostic tool if there
is a problem with the instrument.
The event log can only be viewed via the optional G100 Range - Download Software. It cannot be
viewed on the analyser screen. Applicable events are stored in the event log automatically. No user
intervention is required.
The event log can hold approximately 270 events. If the log becomes full then it begins to over-write
the older events. This can be identified by the index field which starts from event number 1. The log is
cleared when the instrument is reset.
Note For more information on the features listed in this section please contact (Your
company) on (Your telephone) or email (your email@your domain).
Note Please refer to section “Event Log” on page 12-1 of this operating manual for
further information.

General Operational Instructions
Switching the Instrument On
1. To switch on the instrument, press the ‘On/Off’ key briefly. There will be a short beep and a slight
pause followed by the Geotech logo.
2. The power on self-test will then commence (approximately 15 seconds) including warm-up time.
3. Assuming there are no warnings to display the instrument will continue to the ‘Main Read Screen’.
Switching the Instrument Off
1. Purge with fresh air. Run the pump for approximately 30 seconds or until the readings have
returned to normal levels.
2. To switch off the instrument, press the ‘On/Off’ key briefly.
Instrument Main Read Screen
After the analyser has been switched on and the warm-up self-tests completed the analyser will display
the ‘Main Read Screen’.
Soft-Keys:
Peak - Enables the operator to display the peak reading.
Store - Enables the operator to store the reading for viewing/download later.
Hold - Enables the operator to hold the current reading being taken.
Note Before the instrument is switched off a clean air purge should be performed. This
ensures that the instrument is free from gas and ready for the next measurement. This final
purge is especially important for the oxygen sensor as it may degrade if stored when
contaminated with gas.
Note If the ‘Auto Off’ utilities setting is set to ‘Yes’, the analyser will switch off
automatically after 10 minutes if not in use.
