GENERAL INFORMATION FIRST RESPONDER CG - USER HANDBOOK
Alarms can be configured to be non-latching. This means
that the audible and visual alarms will automatically cancel
once the alarm condition has cleared.
Alarms can be acknowledged in CSM mode. This means
that the audible and visual alarms can be suspended
allowing the user to view gas readings in other ranges.
Alarms are acknowledged by a double press of
(Button 4). If, after 30 seconds, the gas detected still
exceeds the alarm level, the audible and visual alarms will
be re-activated.
Alarms can be configured so they cannot be acknowledged.
This forces the instrument to continually display the alarming
range.
Alarms in TRAC Mode
By default, both the audible and visual alarms are disabled.
An option is available to have a ‘Geiger’ style alarm in the
‘EXT’ range. This means that, as the gas concentration
increases, both the sounder and the red LED pulse at an
increasing rate.
Datalogging
The First Responder CG provides the user with an automatic
and manual datalogging function.
Automatic Datalogging
By default, the instrument has automatic datalogging enabled
in CSM and PURGE modes and is confirmed by the ‘STORE’
flag being displayed, as illustrated in Figure 2-8.
