Special Resistance
Use this function to measure the:
• Loop Resistance between the red and
green test leads.
• Resistance of each conductor connected
to the red and green test lead.
• Resistance Difference between the two
conductors.
Connect the red lead to one side of the pair.
Connect the green lead to the other side of the pair.
Connect the black to a reference wire.
Note that the “reference wire” can be a separate
wire or the shield of the cable.
Connect the Strap at a ‘far-end’ access point to the
two conductors of the same pair, and to the reference
wire.
Press the [Enter] key to start the test.
After the 965DSP displays the results, press the
[Enter] key to repeat the test.
Use the [Return] key to return to the Toolbox.
