The Meter allocates memory in such a way as to guarantee
capturing all of the user-specified sample intervals. Event
records will also be captured until the Meter detects the allocated
memory has been used up. At this point, events are not
recorded, but the event counter continues to advance to indicate
the total number of events that occurred. A plus (+) sign appears
after the event count to indicate this condition.
Note
The maximum number of recorded sample intervals is
10,000. The maximum number of recorded events is
15,000 minus the number of sample intervals. These
maximum numbers are proportionally decreased when
the available memory is low.
To change either of the two recording variables, use the cursor
buttons to position the menu selector next to the desired menu
item and press the softkey labeled Edit. Use 5 6 7 and 8 to
move between and set each digit of the selected variable.
If the battery level is anything but full, a message appears at the
bottom of the record menu reminding you of the battery level
before you start the recording session.
Setting the Event Threshold Value
Press the softkey labeled Setup to access the setup menu.
Using the cursor buttons, move the menu selector next to the
menu item labeled Recording and press the softkey labeled
Recording to open the recording setup screen. Using the cursor
buttons, move the menu selector next to the menu item labeled
Event Threshold for Recording and then press the softkey
labeled Edit. Press 7 or 8 to scroll through the event threshold
values. With the desired value selected, press the softkey
labeled Close.
Starting a Recording Session
Once the variables are set, press the softkey labeled Start, at
which point s appears in the display and the green LED
surrounding the power button (O) flashes. Table 8 shows the
recording display and describes the information displayed.
The Menu, Setup, Reference, and Temperature Offset softkey
functions are not available while the Meter is recording. This
ensures that measurements within a recording session are
consistent.
To extend battery life while recording, the Meter may enter a
battery-saver mode five minutes after a push-button is pressed
or IR communications activity ends. If the Auto Power-Off
timeout is set to never, the battery-saver mode is disabled.
Stopping a Recording Session
The recording session will continue until the allocated memory is
used, the batteries expire, the rotary switch is moved, a probe is
inserted or removed from the A or mA/
μ A jacks, or the session is
terminated by pressing the softkey labeled Stop.
Table 9 shows the display and describes the displayed
information after stopping a recording session.
After stopping a recording session, choose to save the recording
session, view the trend data (see the “Viewing Trend Data”
section), or close the recording session. If the session wasn’t
saved before pressing the Close softkey, the data is lost.
