component of the lead cables for source. Care must be taken therefore when drawing a load current since
the voltage drop due to the resistance component (approximately 0.1 Ω on a round-trip basis) of the lead
cables serves as an error.
7.1 Connecting Cables to Terminals
For DC voltage, thermocouple (Figure 5)
Step 1:
Connect the black lead cable for source to the
COM output terminal and the red lead cable to the “VTc” output
terminal.
Step 2:
Connect the other ends of the cables to the input

are correct.
For DC current (Figure 6)
Step 1:
Connect the black lead cable for source to the
“mA-” output terminal and the red lead cable to the
‘’mA+’’ output terminal.
Step 2:
Connect the other ends of the cables to the input of
equipment under test while making sure the polarities are
correct.
