Overview
The front panel controls can be divided into the following groups:
CONTRAST Knob
The CONTRAST Knob adjusts the brightness and viewing angle of the
liquid crystal display. If you are having trouble reading the display,
adjust this knob until the letters and numbers are easily distinguishable
from the background.
The display can also be inverted so that the background is dark and
the characters are light. This adjustment is made on the Setup panel..
See page 4-8.
INSTRUMENT MODE Keys – Navigating the Panels
The INSTRUMENT MODE keys select major instrument operational
and display modes. The display can show any one of seven different
panels, selectable by these keys.
