The Importance of Device Grounding
Ground the instruments (Model LR8432-20) securely
The LR8432-20 is designed so that the chassis is grounded when the three-prong
power cord from the adapter is plugged directly into a grounded, three-prong recep-
tacle.
If a three-prong-to-two-prong adapter must be used on the AC adapter power cord
and therefore the instrument is not grounded, the instrument can still be grounded by
connecting a grounded wire to the GND terminal (a pushbutton terminal) located on
the side of the LR8432-20.
Securely ground the chassis of the device being tested.
Securely connect the chassis of the device being tested to a good ground.
Connecting the chassis GND on the signal side to the instrument chas-
sis
When connecting the chassis ground of the LR8432-20 to the chassis ground of the
device being tested and then to ground, use a wire that is as short and as thick as
possible to bring both pieces of device to equal potential.
