To change the background, press # from the power-up screen, Highlight Background, press
! , highlight Black or White, then $ to save. Press $ exit and save for power-up or % to
apply the changes (without saving for power-up) and exit.
3.2.5.2 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.
3.2.5.3 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.

NOTE: To save any of the functions listed below for power-up it is necessary to first change SAVE DISPLAY CHG at the password

METERS - Output voltage and current are displayed on representations of ana-
log meters.
GRAPH - Displays a sample of the output for the time indicated (see Figure 3-
4). The complete time-line uses 240 points. E.g., selecting 2 Second Graph
means that 2S/240 = 50ms sampling, i.e., every 50ms a snapshot of the output
state is used to produce a single point.
DISPLAY
BACKGROUND White
Black
WHITE - Sets the background to white and displays black characters.
BLACK - Sets the background to black and displays white characters.
KEY PRESS BEEP ON
ERROR ONLY
OFF
ON - provides an audible beep for each key press and for each error received.
ERROR ONLY - silences the beeps for each key press; errors will still cause
beep.
OFF - silences all beeps including key presses and errors except for power-up
and unit faults..
NOTE: Control display contrast by pressing
#
twice to dynamically change the contrast, then press
#
to set when contrast is
acceptable. Contrast can also be set directly by pressing
#
once and using
T
and
R
as needed (see PAR. 3.2.5.1).
