1. Check that the system is safe, and that the preparations described in the pre-
ceding sections have been carried out.
2. Pull the sensor slider, so that the clamp opens.
3. Align the sensor so that the current direction indication matches the direction
of current flow through the conductor that you measure. The conductor should
be in the center of the clamp aperture because the measurement may be
affected by the position within the clamp aperture of the conductor being mea-
sured.
4. Press the opening lever until the UNLOCK indication disappears. Make sure
that the sensor head is properly closed.
If the sensor head is not properly closed, accurate measurement is not possi-
ble.
