Parameter controls

The parameters available for selection depend on the currently
selected modes. All parameters are described below.
Pressing a parameter key selects the parameter indicated by the
illuminated mnemonic above the key.
The current value of the selected parameter is shown on the digital
display. The parameter units are indicated by the LEDs to the right
of the display.
The currently selected parameter is adjusted using the (VERNIER) and
corresponding digit in the digital display. Similarly, the (RANGE ) key
increases or decreases the parameter value by a factor of 10.
When selected, allows the period of the HP81 12A output signal to be
set and or adjusted.
In
EBUR mode, this key is used to set the number of pulses (between
1 and 1999) which will comprise the burst.
