PXD 222 Digitizer
Warnings
Voltage ratings mentioned in the warnings are given as limits for "working voltage." They represent
VAC rms (50–60 Hz) for AC sine wave applications and as VDC for DC applications.
Overvoltage Category II refers to local distribution level, which is applicable to appliances and por-
table equipment.
The terms "isolated" and "electrically floating" are used in this manual to indicate a measurement
in which the digitizer input BNC or banana jack is connected to a voltage different from earth
ground.
The isolated input connectors have no exposed metal and are fully insulated to protect against
electrical shock.
WARNING
To avoid electrical shock or fire if the digitizer input is connected to more that 42 V peak
(30 V rms) or on circuits of more than 4800 VA:
• Use only insulated voltage probes, test leads, and adapters.
• Before use, inspect voltage probes, test leads, and accessories for mechanical
damage and replace when damaged.
• Remove all probes, test leads, and accessories that are not in use.
• Do not connect the ground spring to voltages higher than 42 V peak (30 V rms) from
earth ground.
• When measuring in a CAT II environment, do not apply to any input voltages that differ
by more than 300 V from earth ground.
• When measuring in a CAT II environment, do not apply to the isolated inputs voltages
that differ by more than 300 V from each other.
• Do not apply input voltages above the rating of the instrument. Use caution when
using 1:1 test leads because the probe tip voltage will be directly transmitted to the
test tool.
• Do not use exposed metal BNC or banana plug connectors.
• Do not insert metal objects into connectors.
• Before connecting any input voltages, the unit must be properly installed in the PXI
rack.
• Disconnect the applied voltage(s) before disconnecting probes, BNC leads, test leads,
or accessories.
• Always use the digitizer only in the manner specified
