5.8.3 LOG TIME INTERVAL
The Datalogger records a “snapshot” of conditions at each log time interval. Datalogging uses a consid-
erable amount of RAM, so only select short log intervals if it is fully justified.
NOTE: The flowmeter 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 Time Interval] option list press
Move the cursor to desired interval press
To store your selection press
5.8.4 DATALOGGER EVENTS
The FUH1010PVX 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).
NOTE: An Alarm Event report will be generated immediately 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 Flow Alarm, set the alarm threshold high enough to avoid repetitive triggering. 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 cursor to desired item by
pressing then to select it. Note that a plus sign (+) appears before the item.
To de-select Datalogger Events:
Move the cursor to the item by pressing then . Note that this removes the plus
sign (+) from the item.
After selecting all desired items press to leave the [Datalogger Events] option list.
