3.7.3 Input Impedance
The current probe inserts a load in the circuit to be measured as shown in fig. 3-4.
In particular, take this characteristic into account when measuring a high-fre-
quency current.

3.7.4 Consumption Current
Fig. 3-5 shows the current consumption of the current probe drawn from the
power supply versus the input current in the 30 A range.
