Agilent N6781A Auxiliary Voltage Measurement Input
The auxiliary voltage measurement input is located on the rear panel
of the Agilent N6781A. It is primarily used for battery voltage
rundown measurements, but it is also suitable for general purpose
DC measurements between ± 20 VDC. As shown in the following
figure, auxiliary voltage measurements cannot be made on test points
that are at a greater potential than ± 20 VDC from Common.
Refer to chapter 4 under “Making Measurements” for more
information.
CAUTION
When using the auxiliary voltage measurement input on Model N6781A, no
output terminal or measurement input terminal may be more than ± 60 VDC
from any other terminal and chassis ground.
