2. AC Current Probe Model MN373 User Manual DESCRIPTION The MN373 Catalog 2116 28 is the latest in compact AC current probes Designed to meet the most stringent demands in industry and electrical contracting it also meets the latest safety and performance standards The probe has a measurement range up to 240Arms a range and resolution capable of displaying 10mV of output per amp of measured current a voltmeter accuracy of 0 75 or better to take full advantage of the accuracy of the probe and an input impedance of gt 1MQ 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 0 This symbol signifies that the current probe is protected by double or reinforce
