Setting Date and Time
The Meter’s internal clock is used in the display and for time-
stamping recorded measurements. To change the date and time
as well as the display format, press the softkey labeled Setup.
Position the menu selector next to the menu item labeled
Display. To set the date and time, press the softkey labeled
Date/Time to open the date/time menu. Next, position the menu
selector next to either the Set Date item or Set Time item and
press the softkey labeled Edit. Using 5 and 6, position the cursor
on the date or time element to adjust. Use 7 and 8 to change
the selected date or time element value. Press OK to complete
the action.
Setting Backlight and Auto Off Timeouts
The Meter’s backlight and auto off features use timers to
determine when to turn off the backlight, when to automatically
turn the Meter off or enable the battery saver mode. To set these
timeouts, press the softkey labeled Setup and position the menu
selector next to the menu item labeled Instrument. Position the
menu selector next to the menu item labeled Auto Backlight
Timeout or Auto Power Off and then press the softkey labeled
Edit. Use 7 and 8 to adjust the time to one of the preset
values. Press OFF to disable the timeout feature. Press the
softkey labeled OK to set the selected time. Press the softkey
labeled Close to return to normal Meter operation.
The battery-saver mode is used when the Meter is performing a
recording session or during MIN MAX, Peak record and
AutoHold. The battery-saver mode powers down circuits that are
not involved in the operation of these recording sessions,
including the display. For the record mode, the timeout period is
set to five minutes and is enabled only when the Auto Power Off
timeout is set to a value other than Off. For MIN MAX, Peak, and
AutoHold, the timeout is the time period set for Auto Off.
Setting a Custom dBm Reference
To add a custom dBm reference value, press the softkey labeled
Setup and position the menu selector next to the menu item
labeled Instrument. Next press the softkey labeled Instrument
and position the menu selector next to the menu item labeled
dBm Reference. Next, press the softkey labeled Edit. Use 5 and
6
to position the cursor on a specific digit. Press 7 and 8 to
increment or decrement the digit. With the desired reference
displayed, press the softkey labeled OK to add this value to the
dBm reference list. Only one custom value is allowed. Press the
softkey labeled Close to return to normal Meter operation.
Disabling and Enabling the Beeper
The Meter’s beeper alerts users to the presence of messages,
operator errors such as incorrect lead connections for the
selected function, and newly sensed values for MIN MAX and
Peak recording. Although the beeper is also used for the
continuity function, controlling the beeper for that function is not
done through this setup option. See the “Testing for Continuity”
section for information on the continuity beeper.
To enable or disable the Meter’s beeper, press the softkey
labeled Setup and position the menu selector next to the menu
item labeled Instrument. Next press the softkey labeled
Instrument and position the menu selector next to the menu
item labeled Beeper. Press the softkey labeled Edit to move the
cursor to the on or off selection. Use 7 and 8 to switch the
beeper on or off. The status of the beeper is indicated in the
display’s status bar (see item 12 in Figure 2).
