5.2.4 Datalog

The instrument displays a floppy disk icon to indicate that gas readings are being

recorded in datalog. The instrument stores the measured gas concentration for each

sensor, date and time for each measurement, Site ID, User ID, and other parameters. The

POLI memory is sufficient to record three (3) months’ worth of data for four (4) sensors

at one-minute intervals. 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.

5.2.4.1 Datalog Intervals

Intervals are at a default 60 seconds, and can be changed in a range of 1 to 3,600 seconds.

5.2.4.2 Clear Datalog

This operation erases all data stored in the datalog.

Note: Once the datalog is cleared, the data cannot be recovered.

5.2.4.3 Log 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.

5.2.5 Unit Setting

The sub-menus under unit setting control the Heart Beat Light, Temperature Units, LCD Contrast,

Pump Speed, Language and other parameters.
