AC Current Probe Models SR701 and SR704 User Manual 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 5Q 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 e 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 cu
