Current Measurement
You can measure current in both Scope mode and Meter mode. Scope mode has the advantage
of waveforms being displayed while you perform measurements. Meter mode has the advantage
of high measurement resolution.
The next example explains a typical current measurement in Meter mode.

inputs and the conductor to be measured.
2. Ensure that the red and black connectors correspond to the red and black banana jack inputs.
