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,

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.

• For best accuracy, avoid if possible, the proximity of other conductors which may create
noise.

Tips For Making Precise Measurements
• When using a current probe with a meter, please select the range that provides the best
resolution. Failure to do this may result in measurement errors.

Contaminants cause air gaps between the jaws, increasing the phase shift between
primary and secondary. It is very critical for power measurement.
MAINTENANCE
Warning
• For maintenance use only original replacement parts.
• To avoid electrical shock, do not attempt to perform any service on the device unless you
