Measuring Resistance

For DC current measurements, the polarity of the red
test lead connection will be indicated as well.

Note:
1. If you don't know the magnitude of the current to be
measured beforehand, select the highest range and
then reduce it range by range until satisfactory
resolution is obtained.
2. Never place the test lead probes in parallel with a
circuit or component when the test leads are plugged
into the current terminals.
