  • Page 12: Operator Information

    Your P6022 is shipped with the following accessories: This instruction manual — Read these instructions to familiarize your- self with the features, specifications, and operation of the P6022 current probe. 6-inch ground lead — Use the 6-inch ground lead to ground the shield around the probe transformer at the probe end of the cable.

  • Page 13: Operating Considerations

    Considerations Features and Controls Sensitivity Control — The P6022 termination has a control that allows you to select probe sensitivity. The switch has two positions: 1 mA/mV and 10 mA/mV. When the control is in the 1 mA/mV position, the oscillo- scope displays 1 mV for every 1 mA of current in the circuit under test.

  • Page 14: Insertion Impedance

    When you insert a conductor into the probe, you add impedance to the circuit you are measuring. This additional impedance affects signals; this is particularly important if you are measuring fast rise times. Figure 2 illustrates the equivalent circuit with additional impedance introduced by the P6022. 0.6 H 0.2 nH .025 Ω...

  • Page 15: Probe Shielding

    Operator Information Probe Shielding The P6022 is shielded to minimize the effect of external magnetic fields. However, strong fields can interfere with the current signal being measured. If you suspect that an external field is interfering with your measurement, remove the probe from the conductor, but keep it in the same location as when you made the suspect measurement.
