SIMPLIFIED MEASUREMENT
The 4 wires measurement has many advantages. The errors due
to the resistance of the test leads and the contacts as well as R
A
and R are eliminated. However, in some cases, for example when
B
using the high resistance range (2000 ohms) the four wires
method is not necessary to still have a good percentage of
accuracy (compared to the full scale). The simplified method of
two wires can be used without too much problems. C and P can
1 1
be shorted as well as C and P .
