The Agilent 34330A Current Shunt is a precision 0.001 resistor housed in a plastic case surrounded by epoxy. Output is 1 mV per A of current passing through the shunt. Operating Environment: Indoor use only 2003, 2011 Part Number: 34330-90001 Edition 2, July 2011 Printed in Malaysia Agilent Technologies, Inc. 5301 Stevens Creek Blvd. Santa Clara, CA 95052 USA Safety Notices Do not attempt to repair this sealed device. Do not use this device for any purpose other than indicated in these instructions. Doing so may expose you to bodily injury or cause equipment damage. W ARN IN G 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 voltage limits listed under "Specifications." The following simplified diagram shows how the shunt is used: A CAUTION notice denotes a hazard. It calls attention to an operating procedure, practice, or the like that, if not correctly performed or adhered to, could result in damage to the product or loss of important data. Do not proceed beyond a CAUTION notice until the indicated conditions are fully understood and met. 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 0.001, so the voltage measured by the multimeter is equal to the current multiplied by 0.001. 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.
