Data logging (Instrument Data Storage)
Data logging Instrument must be available with standard data logging.
Event log
Instrument shall record at least 500 events.
Data log capacity
Data log shall record and store data for an average of 50 hours (at one-minute
intervals) without overwriting existing information in normal use.
Gas record content
Data log entries shall contain as minimum date, time and record of peak and
average readings for each gas sensor (oxygen shall be recorded as maximum
and minimum intervals).
Atmospheric record Instrument shall have provisions to record atmospheric temperature changes.
Record intervals
Time span between data records shall be user-selectable from 15 seconds
to 15 minutes.
Data retention
Instrument data stored in memory shall not be lost or corrupted in event of
sudden instrument power loss.
