34401A Service Guide v
IEC Measurement Category II includes
electrical devices connected to mains at an
outlet on a branch circuit. Such devices include
most small appliances, test equipment, and
other devices that plug into a branch outlet or
socket. The 34401A may be used to make
measurements with the HI and LO inputs
connected to mains in such devices, or to the
branch outlet itself (up to 300 VAC). However,
the 34401A may not be used with its HI and LO
inputs connected to mains in permanently
installed electrical devices such as the main
circuit-breaker panel,
sub-panel disconnect boxes, or permanently
wired motors. Such devices and circuits are
subject to overvoltages that may exceed the
protection limits of the 34401A.
Note: Voltages above 300 VAC may be
measured only in circuits that are isolated from
mains. However, transient overvoltages are
also present on circuits that are isolated from
mains. The Agilent 34401A are designed to
safely withstand occasional transient
overvoltages up to 2500 Vpk. Do not use this
equipment to measure circuits where transient
overvoltages could exceed this level.
