For maximum safety, do not touch the product, test cables,
or any other instruments while power is applied to the cir-
cuit under test. ALWAYS remove power from the entire
test system and discharge any capacitors before: connect-
ing or disconnecting cables or jumpers, installing or re-
moving switching cards, or making internal changes, such
as installing or removing jumpers.
Do not touch any object that could provide a current path
to the common side of the circuit under test or power line
(earth) ground. Always make measurements with dry
hands while standing on a dry, insulated surface capable
of withstanding the voltage being measured.
The instrument and accessories must be used in accor-
dance with its specifications and operating instructions
or the safety of the equipment may be impaired.
Do not exceed the maximum signal levels of the instru-

and operating information, and as shown on the instru-
ment or test fixture panels, or switching card.
When fuses are used in a product, replace with same type
and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connec-

connections.
If you are using a test fixture, keep the lid closed while
power is applied to the device under test. Safe operation
requires the use of a lid interlock.
If a screw is present, connect it to safety earth ground
using the wire recommended in the user documentation.
