NOTE: The time interval-based Datalogger records the state of all the alarms at the selected report time only. Therefore, if an alarm condition resets before the report time, it would not appear on the report. Use Datalogger Events to log transient alarms. This mode generates a report upon the detection of an alarm event.

2.9.3 LOG TIME INTERVAL

The Datalogger records a “snapshot” of conditions at each log time interval. Datalogging uses a con- siderable amount of RAM, so only select short log intervals if it is fully justified.

NOTE: The meter maps the first Datalogger report time to an even division of its clock. Sub- sequent reports will conform to the selected interval.

To set the Log Time Interval:

To access the [Log Interval] option list press

Move the cursor to desired interval by pressing

To store your selection press ENT

2.9.4 DATALOGGER EVENTS

System 1010 offers “event-based” data logging that operates concurrently with “time interval” based data logging. The event-based function generates a Datalogger report upon the triggering of any of the alarms. This is useful for recording transient alarms (e.g., a liquid interface, or a short aeration alert.)
