1.3 Principles of measurement
The MGR10 generates a constant current which is connected using the +I and -I leads across the
unknown resistance to be measured. This current also passes through a stable and accurate internal
standard. The volt drop across the unknown resistance is then measured together with the volt drop
across the internal standard, the ratio of these two measurements is then computed and displayed on
the front panel.
