Custom Full Brightness Sets the display to red, the same as that available under Set Test Color with the
intensity of the full color hue. You can adjust the hue using the front-panel knob. When the screen appears
black, you have reached the end of the hue adjustment. The screen will appear solid red with full hue intensity
if the display is working correctly. If the analyzer fails this test, the screen will not adjust to a fully intense red
hue. Press Esc to return to the display test instruction screen.
Keyboard Test Displays a table screen that enables you to verify the correct operation of your
front-panel keys, menu keys, navigation keys, and the front-panel knob. The display lists all of the
keys on the analyzer followed by a zero (0). The integer toggles by one every time you press the
listed key. Press Esc to exit the Keyboard Test. Pressing the Mode key will not exit the test.
