Measurement Considerations
Observe the following guidelines when making measurements,
refer to Figure 1:
•
Center the conductor inside the Current Clamp jaw.
•
Make sure the clamp is perpendicular to the conductor.
•
For optimal reading, make sure the conductor is positioned
between the alignment marks on the jaws of the Current
Clamp.
•
Avoid taking measurements close to other current-carrying
conductors.
Operation
To use the Current Clamp:
1.
Connect the clamp cable to the measurement
instrument’s current inputs.
2.
Make sure the measurement instrument is set to the
proper range.
3.
Connect the current clamp jaws around the conductor
to be measured.
