5.0 General Operational Instructions
Note:
Fully charge the unit before use when the instrument is first received or if the
instrument has been in storage for six months or more.
5.1 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 with a short pre-determined self-test
sequence.
3)
Assuming there are no warnings to display the instrument will continue to the ‘Main
Read Screen’.
5.2 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.
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.
2)
To switch off the instrument, press the ‘On/Off’ key briefly.
Note: If the ‘Auto Off’ utilities setting is set to ‘Yes’, the analyser will switch off
automatically after 10 minutes if not in use.
5.3 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’.
