When measuring high impedances (i.e. low capacitance), use cables that are shielded all
the way to the test clips. This will minimize stray capacitance between the high and low
test leads. Using the provided 4-terminal test leads (shielded coax) is recommended. If a
different test cable is used, it should be constructed from coaxial cables. Twist the coax
cables and make sure the cables are arranged as shown in the cross-sectional view to theS
right. This will minimize errors when performing high impedance measurement. The
shorter the cables, the less the error.
