Strip the insulation of the power cable that you cut, and attach round crimped terminals if
necessary. Connect the power cable to the WT310E in the following ways.
• Power-source-side cable: Connect to the ± current input terminal.
• DUT side cable: Connect to the CURRENT current input terminal.
Pay attention to the terminal polarities so that you don’t attach the cables to terminals (C and ±) with the
wrong polarities.

Connect the voltage measurement cables to the power supply terminals of the DUT.
Use cables that meet the following conditions.
• Sufficient dielectric strength for the voltage of the circuit under measurement
• Of a size to which the 758931 Safety Terminal Adapter can be attached
• Covering: max. diameter 3.9 mm
• Core wire: max. diameter 1.8 mm
