1 Check that the system is safe and that the preparations
described in the preceding section have been carried out.
2 Pull the sensor opening lever with the sensor head opens.
3 Align the sensor so that the current direction indication
corresponds to the direction of current flow through the
conductor to be measured. Also, align the clamp so that
the conductor is in the center of the sensor aperture.
4 Press the opening lever on the sensor head until the
"UNLOCK" indication disappears. Also check that the
opening lever is firmly locked and the sensor head
securely closed.
5 Before making current measurements, the oscilloscope
must be set up as follows.
