resistance along the leakage path from the
conductor over the surface of the termination
may be less than that within the major length of
the cable. Under such conditions the guard
feature of the test set is useful in excluding the
leakage of the surface path from the
measurement. This is easily accomplished by
forming an electrode by wrapping a bare wire
around the outer surface of the termination. This
wire electrode, which will intercept the surface
current, must be connected to the test set guard
terminal (BLUE crocodile clip).
The same guard principle can be used on other
apparatus where a suitable intercepting electrode
can be added on a temporary basis.
