287/289 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 54 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. MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664
