A WARNING notice denotes a hazard.
It calls attention to an operating proce-
dure, practice, or the like that, if not
correctly performed or adhered to,
could result in personal injury or death.
Do not proceed beyond a WARNING
notice until the indicated conditions are
fully understood and met.
CAUTION
A CAUTION notice denotes a hazard.
It calls attention to an operating proce-
dure, practice, or the like that, if not
correctly performed or adhered to,

Instructions for Use
The Agilent 34330A Current Shunt is
a precision 0.001Ω resistor housed in a
plastic case surrounded by epoxy.
Output is 1 mV per A of current
passing through the shunt.
WARNING
Install the shunt in the multimeter
voltage input terminals before use. Do
not remove the shunt with a current
source still connected, as there may be
danger of shorting the banana plugs to
ground. Observe the current and volt-
age limits listed under “Specifications.”
The following simplified diagram shows
how the shunt is used:
Insert the shunt’s banana-plug outputs
into the main voltage inputs on the
multimeter (not the high ampere
inputs). Then connect the current
source to be measured to the shunt’s
input terminals (binding posts). The
multimeter will read the IR drop caused
by the input current through the shunt.
The precision resistance of the shunt is
0.001Ω, so the voltage measured by the
multimeter is equal to the current
multiplied by 0.001Ω. Thus, the voltage
reading sensitivity is 1 mV/A. For a
15 A current, the voltage reading is
15 mV. Select an appropriate voltage
range on the multimeter. See your
multimeter User’s Guide for further
information.
Cleaning Instructions
Wipe with a soft cloth, moistened
slightly with water, if needed.
