9.3.8 Datalog
The instrument displays a floppy disk icon to indicate that a datalog is being recorded. The instrument
stores the measured gas concentration for each sensor, date and time for each measurement, Site ID, User
ID, and other parameters. The MultiRAE memory is sufficient to record six months’ worth of data for
five sensors at one-minute intervals, 24/7. All data are retained (even after the unit is turned off) in non-
volatile memory so that they can be downloaded at a later time to a PC.
9.3.8.1
Clear Datalog
This operation erases all data stored in the datalog. Select “Clear Datalog,” and then “Yes.”
Note:
Once the datalog is cleared, the data cannot be recovered.
9.3.8.2
Datalog Interval
Intervals are shown in seconds. The default value is 60 seconds. The maximum interval is 3600 seconds,
and the minimum is 1 second.
9.3.8.3
Sensor Selection
You can choose which sensors’ data are included in the datalog. The entire list of installed sensors is
shown, and you can individually select whether their data is included.
Note:
Turning a sensor off in the list does not change or erase its settings.
