You
must
insulate signal connections for the maximum voltage for
which the device is rated. Do
not
exceed the maximum ratings for
the device. Remove power from signal lines before connection to
or disconnection from the device.
Caution
National Instruments measurement products
may be classified as either Measurement Category I or II.
Operate products at or below the Measurement Category
level specified in the hardware specifications.
Measurement Category
1
: Measurement circuits are subjected to
working voltages
2
and transient stresses (overvoltage) from the
circuit to which they are connected during measurement or test.
Measurement Category establishes standardized impulse
withstand voltage levels that commonly occur in electrical
1
Measurement Categories as defined in electrical safety standard IEC 61010-1.
2
Working voltage is the highest rms value of an AC or DC voltage that can occur
across any particular insulation.
