2.6 Connection to Device under Test
Figure 2-13 illustrates the connection of the 1855 instrument to a DUT using the 1855-01 Lead
Set. For Leakage Current, Insulation Resistance and Withstand Voltage Tests, the red alligator
clip/BNC cable is connected between the silver INPUT terminal on the 1855 unit and the high
side of the device under test. The black alligator clip/banana cable is connected between the
white HV (-) terminal on the 1855 unit and the low side of the DUT.
