When installing equipment where access to the main power cord is restricted, such as
rack mounting, a separate main input power disconnect device must be provided in
close proximity to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments
while power is applied to the circuit under test. ALWAYS remove power from the
entire test system and discharge any capacitors before: connecting or disconnecting
cables or jumpers, installing or removing 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 accordance with its specifications and
operating instructions, or the safety of the equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories, as defined
in the specifications and operating information, and as shown on the instrument or test
fixture panels, or switching card.
When fuses are used in a product, replace with the same type and rating for continued
protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits,
NOT as protective earth (safety ground) 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.
