Teledyne LeCroy CP Series current probes are often used in applications such as the design and test of switching power supplies, motor drives, electric vehicles, and uninterruptible power supplies. Teledyne LeCroy current probes do not require the breaking of a circuit
or the insertion of a shunt to make accurate and reliable current
measurements. Based on a combination of Hall effect and transformer
technology, Teledyne LeCroy current probes are ideal for making accurate
AC, DC, and impulse current measurements.
