22. 6 Troubleshooting Describes points to check before requesting service Chapter 7 Service Explains how to get the unit serviced 11 Chapter 1 Product Outline 1 1 Product Outline The 3283 Clamp on Leak HiTester is designed for wide range measurement on live circuits from very small leak currents up to load currents of 200 amperes The clamp part is made of material with high magnetic permeability to minimize adverse effects caused by external magnetic fields and to reduce tolerances due to the position of the measured conductor 1 2 Features High sensitivity range with 10 mA full scale point Allows accurate measurement even of minute leak currents resolution 10 uA e Wide measurement range Five range settings from 10 mA to 200 A make the 3283 suitable for many applications Microprocessor controlled functions In spite of the compact dimensions of the unit versatile functions such as SLOW and MAX MIN are made possible by the built in microprocessor Chapter 1 Product Outline 12 True rms indication The true rms conversion circuit delivers accurate results not affected by leak current distortion eFiltering The widespread use of switching power supplies and equipment incorporating inverter technology frequently causes harmonics to be superimposed in the leak current waveform The filter in the 3283 allows two kinds of measurement for leak current caused by insulation faults a
