2. CURRENT MEASUREMENT

2.1. MEASUREMENT PRINCIPLE

The sensor provides an image of the derivative of the current analysed.
The electronic housing provides an image of the integral of the sensor output.
The resultant of these two operations on the output of the housing is the image of
the current analysed.
The sensor used provides:
very good linearity with no saturation effect (and so no heating);

insensitivity to direct current (it is possible to measure the AC component of any

AC + DC signal);
light weight (no magnetic circuit).


2.2. USE

2.2.1. CONNECTION
Connect the cord to the input of an oscilloscope having an input impedance of at
least 1MW, in AC mode.
Switch the electronic housing on by sliding the switch to a position. The green
indicator lights.
