3. Limits: Rotating this knob sets the upper limit of the display. Pressing and
then rotating sets the lower limit. Top and bottom limits are adjustable in 1
dB increments. This function is available on the custom meter scale only.
4. Lower Scale: (This function is available on the custom meter scale only.)
This knob controls the size of the lower part of the scale in relation to the
overall scale. You can reduce the size of the lower part of the scale to allow
more accuracy in viewing the upper part. Rotating this button sets the
division point between the upper and lower parts of the scale in 1 dBr
increments and it moves the arrow in the meter display up or down. As you
adjust the division, the percent of full scale (%FS) in the Size section of this
function, is continuously recalculated. Likewise, if the Limits control is
adjusted, the %FS is also recalculated.
