Terminal-to-Terminal Current is the current that runs between− and ＋ terminals when measuring resistance. There may besome 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 rightside of each range. Readings at each range shall be converted
by multiplying the values (shown below).
x1 k (80 µA) Range : LI scale x10, and read as µA.
