Measurement and application

Current waveform measurements depend on both probe placement and signal conditioning. Start with the conductor shape, available space and the waveform you need to observe, then consider the coil and measurement equipment together.

Selection and connections

Distinguish temporary testing from fixed installation, and confirm the required coil, integrator and cable combination rather than assuming that similar looking accessories are interchangeable.
