To use a Pearson current transformer one needs an oscilloscope (or for RF work sometimes an RF voltmeter) and an appropriate length of coaxial cable (usually 50 ohms impedance). The output receptacle of the current transformer is connected via the coaxial cable to the high-impedance oscilloscope or voltmeter input. The conductor carrying the current to be measured is passed through the hole in the current transformer. The voltage waveshape as displayed on the oscilloscope will then be a faithful reproduction of the actual current waveshape (within the limitations of rise time and droop specified for the particular model used). The voltage amplitude will be related, on a linear basis, to the current amplitude by the sensitivity or transfer impedance in volts-per-ampere.
* Maximum current-time product can be obtained by using core-reset bias as described in the Application Notes. 2 Ampere-second is typical without bias.
