The NEW REF (New Reference) key is active during error mode operation, and establishes the
present output value as a new reference for meter error computation.
K
S
The SETUP (Setup Menu) key puts the 5080A in the setup mode, displaying the setup menu in the
Control Display. Setup options can be selected using the softkeys under the Control Display.
L
R
The RESET (Reset Calibrator) key aborts the current operating state of the 5080A and returns it to
the power-up default state, except when operating under remote control.
M
G
The CE (Clear Entry) key clears a partially completed keypad entry from the Control Display. If
there is a partially completed entry when CE is pressed, the output is unaffected.

The EDIT FIELD (Edit Output Display Field) key and associated left/right arrow keys provide step
adjustment of the output signals. If any of these keys are pressed or the knob is rotated, a digit on
the Output Display becomes highlighted and the output increments or decrements as the knob is
rotated. If a digit rolls past 0 or 9, the digit to its left or right is carried. An error display appears on
the Control Display, showing the difference between the original (reference) output and the new
output.
The L and W keys adjust the magnitude of changes by moving the highlighted digit. The e
key allows you to move from voltage or current to frequency and back. In practice, for voltage and
current outputs, the knob and arrow keys are used to adjust output until the UUT reads correctly.
The error display then displays UUT deviation from the reference.
O
The power switch turns the power on and off. The switch is a latching push-push type. When the
switch is latched in, power is on.
