D. Measuring Currents
If the fuse burns out during measurement, the Meter

equipment under test, check the Meter’s fuses
before measuring current. Use proper terminals,
function, and range for the measurement. Never
place the testing leads in parallel with any circuit
or component when the leads are plugged into the
current terminals.
