Delete All
The ‘Delete All’ function enables the user to check how many readings have previously been taken
and clear them if necessary.
Note: Before readings are actually deleted a caution message is displayed; once readings have
been deleted they cannot be recovered. To enable TWA to be calculated the last 24 hrs worth of
readings are stored.
The instrument can store up to 1,000 readings. The reading structure is fixed and may contain
optional parameters not activated for your particular instrument configuration, i.e. oxygen,
temperature and humidity.
Once the reading memory is full it is not possible to store any more readings. When full and the
‘Store’ key is pressed or data logging is activated the instrument will show a brief message stating that
the memory is full and that no further data will be recorded.
From the ‘Main Read Screen’ press the ‘Menu’ key on the instrument panel.
Press ‘Key 4 - View Data’.
To clear the readings press the soft-key ‘More’ followed by ‘Key 1 - Delete all’.
