Guarding
Guarding reduces the leakage current between the measurement points
and
instrument. This is important when you measure low current.
The following figure shows the theory of guarding. The buffer amplifier (×1) keeps
the potenti
al of the guard conductor at the same potential as the force conductor, so
current does not flow between the force and guard conductors. Therefore, the
current measured by SMU is same as current at measurement point because no
current is leaked.
