6-6-2 Terminal to Terminal Current (LI)
Terminal-to-Terminal Current is the current that runs between
− and + terminals when measuring resistance. There may be
some cases that the impedance of measured object varies,
especially when measuring semi-conductors, due to selfheating caused by current running while measuring resistance.
The maximum LI values are printed on the body panel, at right
side of each range. Readings at each range shall be converted
by multiplying the values (shown below).
Range : LI scale x10, and read as µA.
x1k (80µA)
x100 (800µA) Range : LI scale x100, and read as µA.

Wire breaking point
Cx 2
Cx 1>Cx 2
Continuity or open-wire check of parallel cords, as shown in Fig,
can be done by measuring capacitance between the core wires
(conductors) as a comparison test.
Longer cords are easier to check the detection of the open-wire
because the capacity value lost by leakage between the wires is
proportioned to the length of the wires.
