To deselect Datalogger Data:
Move the cursor to the data item then press . Note that this removes the plus
sign (+) from the item.
After selecting/deselecting all desired items press to leave the [Datalogger Data]
option list.
2.7.3 LOG TIME INTERVAL
The Datalogger records a “snapshot” of conditions at each log time interval. Datalogging
uses a considerable 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. Subsequent 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
2.7.4 DATALOGGER EVENTS
System 1010 offers “event-based” data logging that operates concurrently with “time inter-
val” 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). Note: An Alarm Event report will be generated imme-
diately after the transition from a non-alarm to an alarm event. The reverse situation (alarm
state to non-alarm state) does not trigger the event-based Datalogger.
Event-based Datalogger messages conserve memory. However, if you use this feature to monitor
a level such as Interface Alarm, set the alarm threshold high enough to avoid repetitive trig-
gering. You must select Site ID (Name) and Time to “time-stamp” the alarm events. Note that
on the Datalogger report, a [-] represents a reserved letter code space (inactive alarm) and a
letter code represents an active alarm.
To select Datalogger Event items:
To access the [Datalogger Events] option list press
Move the cursor to desired item by pressing then press to select it.
Note that a plus sign(+) appears before the item.

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.
To select Datalogger Data items:
To access the [Datalogger Data] option list press
Move the cursor to a desired data item by pressing then press to select it.
Note that a plus sign (+) appears before the item.
