AC Current Probe
Models SR701 and SR704
User Manual
DESCRIPTION
The SR701/SR704 AC Current Probes (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 1000 Arms and are compatible with any AC ammeter,
multimeter, or other current measurement instrument with an input impedance lower than 5 Ω.
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.
• Do not use the probe if damaged. Always connect the current probe to the measuring device before it is
connected around the conductor
• Do not use on non-insulated conductor with a potential to ground greater than 600 V CAT III pollution 2.
Use extreme caution when clamping around bare conductors or bus bars.
• Before each use, inspect the probe; look for cracks in housing or output cable insulation.
• Do not use clamp in wet environment or in locations that hazardous gases exist.
• Do not use the probe anywhere beyond the tactile barrier.
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 symbol signifies that this is a type A current sensor and that application near and
removal from HAZARDOUS LIVE conductors is permitted.
DEFINITION OF MEASUREMENT CATEGORIES
CAT IV: For measurements performed at the primary electrical supply (< 1000 V), such as
on primary overcurrent protection devices, ripple control units, or meters.
CAT III: For measurements performed in the building installation at the distribution level, such
as hardwired equipment in fixed installation or circuit breakers.
CAT II: For measurements performed on circuits directly connected to the electrical
distribution system, such as measurements on household appliances or portable
tools.
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.
