Settings
The setting values are indicated by the three
rightmost digits of the display. The LED indi-
cators adjacent to the setting value symbols in-
dicate the setting value being presented on the
display. Additional setting values are indicated
by the leftmost red digit of the display. The set-
tings can be entered from the push-buttons on
the front panel or over the serial port.
