AC Current Probe 

Model SR759 

User Manual

 

 

DESCRIPTION 

The SR759 (Catalog #2116.33) is designed for use in industrial environments. The ergonomic design allows 

itm to easily attach to cables or small bus bars. The “circular” jaws guarantee a very good accuracy and low 

phase shift. The probe has four measurement ranges with the highest range measuring to 1000Arms 

continuous and is compatible with any AC Voltmeter, multimeter, or other voltage measurement instrument 

that has the following features: Range and resolution capable of displaying 1mV of output per amp of 

measured current; Voltmeter accuracy of 0.75% or better to take full advantage of the accuracy of the 

probe; Input impedance of 

 10M

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.
