AC Current Probe
Models SR701 and SR704
User Manual
DESCRIPTION
The SR701/SR704 (Catalog #2116.29 and #2116.30) are designed for use in industrial environments. The
ergonomic design allows them to easily attach to cables or small bus bars. The "circular" jaws guarantee a
very good accuracy and low phase shift. The probes have a measurement range up to 1000Arms and are
compatible with any AC ammeter, multimeter, or other current measurement instrument with an input
impedance lower than 5Ω. To achieve the stated accuracy, use the SR701/SR704 with an ammeter having
an accuracy of 0.75% or better.
WARNING
These safety warnings are provided to ensure the safety of personnel and proper operation of the
instrument.
• Read the instruction manual completely and follow all the safety information before attempting to
use or service this instrument.
• Use caution on any circuit: Potentially high voltages and currents may be present and may pose
a shock hazard.
• Read the safety specifications section prior to using the current probe. Never exceed the
maximum voltage ratings given.
• Safety is the responsibility of the operator.
• ALWAYS connect the current probe to the display device before clamping the probe onto the
sample being tested.
• ALWAYS inspect the instrument, probe, probe cable, and output terminals prior to use. Replace
any defective parts immediately.
• NEVER use the current probe on electrical conductors rated above 600V in overvoltage
Category III (CAT III). Use extreme caution when clamping around bare conductors or bus bars.
INTERNATIONAL ELECTRICAL SYMBOLS
This symbol signifies that the current probe is protected by double or reinforced insulation. Use
only factory specified replacement parts when servicing the instrument.
This symbol signifies CAUTION! and requests that the user refer to the user manual before
using the instrument.
This is a type A current sensor. This symbol signifies that application around and removal from
HAZARDOUS LIVE conductors is permitted.
DEFINITION OF MEASUREMENT CATEGORIES
Cat. I: For measurements on circuits not directly connected to the AC supply wall outlet such as protected
secondaries, signal level, and limited energy circuits.
Cat. II: For measurements performed on circuits directly connected to the electrical distribution system.
Examples are measurements on household appliances or portable tools.
Cat. III: For measurements performed in the building installation at the distribution level such as on
hardwired equipment in fixed installation and circuit breakers.
Cat. IV: For measurements performed at the primary electrical supply (<1000V) such as on primary
overcurrent protection devices, ripple control units, or meters.
RECEIVING YOUR SHIPMENT
Upon receiving your shipment, make sure that the contents are consistent with the packing list. Notify your
distributor of any missing items. If the equipment appears to be damaged, file a claim immediately with the
carrier and notify your distributor at once, giving a detailed description of any damage.
