Chapter 1 Product Outline
1.2 Features
･ High-sensitivity range with 10-mA full-scale point
Allows accurate measurement even of minute
leak currents (resolution 10μA).
･ 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.
･ True rms indication
The true rms conversion circuit delivers
accurate results not affected by leak current
distortion.
･ Filtering
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 and for
leak currents including harmonics.
･ Output jack
The output jack allows easy connection to a
level recorder or other equipment (level
recorder output: DC, waveform output: AC).
