  1. When using a power adapter booster (standard). 15 A-Pk, 5 V-RMS without oscilloscope-provided power only. An MXR/EXR enables max current range without using the power adapter.
  2. Auto-selected based on Amps/division setting.
  3. The maximum number of current probes supported by InfiniiVision oscilloscopes is limited depending on the oscilloscope. Infiniium oscilloscopes have no limitations.
  4. Manually selectable.
  5. A wider input range is possible when using the user-defined head and Rsense.
