Pressing the DISPLAY VIEW REF button displays the power

and buttons.
The DISPLAY BRIGHT button is used to adjust the intensity
of the front panel display. Repeatedly pressing this button
cycles the brightness through five possible intensity steps
ranging from brightest to dark. The keypad is back lighted
for viewing in a dark environment. The brightness control
also affects the illumination of the switches.
The DISPLAY ZOOM button controls the sensitivity of the
bargraph display. Pressing DISPLAY ZOOM forces the
bargraph into a high sensitivity mode where each segment
represents 0.7% (ten times the normal sensitivity) of the total
power within the selected gain range. In ZOOM mode, the
end points of the bargraph blink.
The DISPLAY RATE button controls the speed at which
measurements are taken by the 6810B. Repeatedly
pressing DISPLAY RATE causes the instrument to cycle
through the three possible rates. The measurement rate is
determined by viewing the flashing indicator above the
POWER display.
