8. FRONT PANEL SETUP KEYS
Counter Front Panel
There are four front panel keys, which change function for the Run Mode and Menu Mode,
effectively becoming eight keys. The keys are labeled with alphanumeric captions (MENU,
PEAK, RESET, ALARMS) for the Run Mode and with symbols (
right arrow, right
triangle, up triangle, left arrow) for the Menu Mode.
FRONT PANEL LOCKOUT
The Menu Mode will not work with most meters shipped from the factory, since all menu
items have been disabled in software and a lockout jumper is in place. This jumper needs to
be removed for the Menu Mode to work, and values under _
Loc 1 through _ Loc 4 need to
be set to "0" via the front panel for these menu items to be available. See Section 9. The
paragraphs below assume that all lockout features have been removed.
MENU MODE KEY ACTION
In the Menu Mode, pressing a key momentarily advances to the next item. Holding down
the key advances through multiple menu items for fast menu navigation.
KEYS IN RUN MODE
MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing
MENU repeatedly will step the meter through the various menu items (if these have not
been locked out) and then back to the Run Mode.
PEAK Key. Pressing PEAK causes the peak value of the input signal to be displayed.
The peak display blinks to differentiate it from the normal present value display.
Pressing PEAK again will return the display to the present value.
