original configuration (see Section 12)
or return for service.
If a FATAL error is rectified, a lower priority
error code may then be displayed.
E0, E01, E02, E03 are normally non fatal but may
be configured as fatal using SetPortable.
An instrument with a FATAL error may not be
used but may only be switched off or rectified.
The instrument will raise an audible alarm in
the event of a fault.
12. Datalogging and Datacommunications
Gasman II has an integral datalogging
feature which takes regular readings and stores
them in memory. When the memory is full,
oldest data is overwritten so the instrument will
always contain the most recently accumulated
data.
As standard, a reading is taken every minute
which will give a minimum logging capacity of
30 hours. If gas readings are zero or unchanging,
this capacity is extended by compression
software to as much as 3000 hours. The basic
capacity can be altered by changing the sample
rate.
Note: If batteries fully discharge, logged data
may be lost.
To change sample rate, upload the log, clear
the log or alter any other instrument settings, it is
necessary to use a PC running
SetPortable
software. To view the log, use
Logmanager
.
Historical time is calculated relative to current
PC time, so ensure the date and time are set
