Input Impedance - Iwatsu SS-530 Instruction Manual

Typical Characteristics

Input impedance

The location where the sensor is clamped will exhibit
impedance as shown in Figs. 5 and 6, which inserts a load
in a circuit under measurement. In particular, take this
characteristic into account when measuring a high-frequency
current.
