Front Panel Keys (cont.)
B
Enables or disables output from an amplifier, when
it would not otherwise be automatically selected.
Sets the Calibrator to standby if this selection
moves the output location.
When available, an amplifier is automatically
selected for output settings that exceed Calibrator
capabilities, but fall within the limits of the selected
amplifier. The B key is only needed to activate
an amplifier for an output setting that is available
from either the Calibrator or from the amplifier.
This allows you to take advantage of amplifier
capabilities other than extended range (i.e. higher
compliance voltage).
For both voltage and current, the amplifier is
assumed to be a 5725A unless another model is
designated in the Setup menus.
P
Aborts the current operation of the Calibrator and
recalls the previous menu. Some menus display a
more specific label for this key, such as "DONE
setting up."
u
Softkeys
The functions of the five unlabeled softkeys are
provided through each menu in the Control
Display, with each function located directly above
the softkey that activates that function. Many of
these functions access new menus that contain a
new set of functions for the softkeys, providing
access to many capabilities and configuration
options through the menu tree.
POWER switch
Turns the power on and off.
