Do not exceed the maximum signal levels of the in-
struments and accessories, as defined in the specifi-
cations 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 same
type and rating for continued protection against fire
hazard.
Chassis connections must only be used as shield con-
nections for measuring circuits, NOT as safety earth
ground connections.
If you are using a test fixture, keep the lid closed while
power is applied to the device under test. Safe opera-
tion 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 documenta-
tion.

bined effect of normal and common mode voltages.

that might result in personal injury or death. Always
read the associated information very carefully before
performing the indicated procedure.
