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
The safety warnings are provided to ensure the safety of personnel and proper operation of the
instrument. Read the instruction completely.
• 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 600V 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 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 IV: For measurements performed at the primary electrical supply (<1000V) 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 on
hardwired equipment in fixed installation and circuit breakers.
CAT II: For measurements performed on circuits directly connected to the electrical distribution system.
Examples are 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.
