Probing Principles
4.
To adjust for a current null, adjust the
current in one of the conductors until the
displayed measurement is zero.
Extending Current Range
If your measurement exceeds the maximum current rating of the connected probe, you can extend the AC and DC current ranges
without exceeding speci
fi
ed limits by using the following methods.
WARNING.
To avoid personal injury or equipment damage, do not exceed the speci
fi
ed electrical limits of the probe or any
applicable accessories. When using multiple conductors, do not exceed current limits on either conductor.
Extending DC Range
If you want to measure a low-amplitude AC component that is superimposed on an extremely large steady-state DC component
(such as in a power supply), or if you want to extend the DC current range of your probe, you can add offset (bucking) current with
a second conductor.
