Users Manual

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/μA 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.
