3.2.5.3 ENABLING/DISABLING AUDIBLE BEEPS
From the power-up screen (Figure 3-3), press
#
, then refer to Table 3-3 and modify the setting
using the techniques described in PAR. 3.2.4). Even though audible beeps are set to off, the
beeps will still sound upon power-up or detection of a power supply fault.
3.2.5.4 DISPLAYING METERS OR GRAPH (TIME LINE)
The top screen can be configured to either display graphical analog meters (Figure 3-3) show-
ing a coarse representation of voltage and current in addition to the digital readout, or a graphi-
cal time line (Figure 3-4). The graphical time line is not an oscilloscope type display. Instead, it
samples the output and refreshes the screen at a specified interval: 75, 30, 15, 7.5, 3.8, 1.5, 0.8,
0.3, 0.15, 0.08 or 0.04 Seconds. This can be useful when executing a waveform, although it is
not a substitute for monitoring the output with an oscilloscope for precision. There is no correla-
tion between voltage and current graphs. For the best graphical representation choose the
graph time that is closest to, but greater than, the waveform time duration.
From the power-up screen, press
#
, then highlight the Graphic Display setting and press
!
.
Highlight any of the meters or one of the graph selections and press
$
to save. Then press
$
to save for power-up or
%
to exit.
3.2.5.5 WAVEFORM STOP
Output Off - When waveform is stopped (e. g., by pressing
%
), output freezes at whatever level
the waveform was at when
%
was pressed, then after a brief delay output is set to STANDBY
(disabled).
Last Level - When waveform is stopped (e. g., by pressing
%
), waveform runs through full
cycle. The output stops at the last generated value of the waveform (e.g., for a sinewave seg-
ment of 0° to 270°, 10V amplitude, 0V offset, when
%
) is pressed the output will end up at -10V
Current lvl - When waveform is stopped (e. g., by pressing
%
), output freezes at whatever level
the waveform was at when
%
) was pressed.
3.3 LOCAL MODE OPERATION
Local operation of the BOP power supply can be accomplished from the front panel via the 27
key keypad, and the ADJUST knob. All indications are provided by the 4-inch graphical display
(LCD).
3.3.1 SETTING LOCAL MODE
When the power supply is turned on, it is automatically set to Local mode. If the unit is in
REMOTE mode and the display shows F1-LOCAL, pressing
!
sets the unit to LOCAL mode.
3.3.1.1 KEYPAD LOCKOUT
To prevent the unit from entering local mode from the front panel once remote mode has been
entered, refer to PAR. 3.2.4.3 and assign a password to “Keyboard @ local.“ Then the unit
will not permit local operation until the proper password has been entered (see PAR. 3.2.4.4).
NOTE: The
#
key can still be used to adjust display contrast before entering the password.
If the
!
key legend is “F1 - LOCAL LOCK OUT,” the keypad has been locked by the remote
command, SYST:KEYB DIS (see PAR. B.135). To unlock the keypad, either send SYST:KEYB
ENAB or turn the unit off then on again.
