Operators Familiarization
Normally, the menu display turns off after a measurement function is selected
(if not configured to remain on), and the name and value of a selected
measurement function appears in the top Sine of the crt readout. However,
when it is possible to make more than one selection from the menu list (or if
the menu is configured to remain on), the display menu will remain on for
making further choices until the CLEAR DISPLAY button is pressed or MENU
OFF selected (if a menu choice). The service menu can be turned off by
selecting QUIT from the menu or pressing the CLEAR DISPLAY button.
Clearing the Menu and Cursors Display
The CLEAR DISPLAY button clears displayed menus, turns off measurement
functions (including TRACK MEASMT cursors), and turns off the TRACK
TRIG LVL and TRACK /b cursors. Depending on what menus and measure­
ments are displayed at the time, you may have to press the CLEAR DISPLAY
button as many as three times to completely clear the display.
If a menu is on, pressing the CLEAR DISPLAY will remove the menu and
return the display to a normal operating mode. Measurement functions are
turned off with the second press (or the first press if no menu is displayed).
Finally, the TRACK TRIG LVL and TRACK/& cursors are canceled with a third
press (or the first press if no menu is displayed and no measurement function
is active).
Setting Measurement Channel
Press SET MEAS’MT CHANNEL button to call up one of the menus for setting
the measurement channel(s).There are one-page menus available for volt­
meter and rise/fail measurements and single-channel C/T measurements,
and two-page menus for all the measurements that can have two different
measurement channels. Each menu lists input channels that can be selected
for the active measurement mode.
If the SET MEAS’MT CHANNEL button is pressed for an invalid mode, one of
the following messages will be displayed in the top line for about two
seconds.
*
SELECT A MEASUREMENT—When no measurement mode is active.
NO MEAS CHANNEL NEEDED — When a selected measurement mode
(such as cursor time) does not require a measurement channel setting.
When a SET MEAS’MT CHANNEL menu Is displayed, switching between A
and ALT Horizontal MODES normally clears the menu and turns off the active
measurement mode.
