Brightness
Use this softkey to adjust the display brightness (intensity). The display
is set to maximum brightness at the factory. To change the brightness,
press
Utility > Display > Brightness. The current value shown in the active
entry area is a relative value for brightness. Increasing the number
increases the brightness; decreasing the number decreases the
brightness. You can adjust the brightness value to any number from 1
through 50. (To adjust the brightness via remote operation, set the
value from 0.02 to 1.0.) Use the front panel knob, the up and down
arrow keys, or enter a value using the numeric keypad and press the
Enter terminator softkey.
Brightness is a persistent state; it is not affected by an instrument
preset or by a power cycle.
