Pull the probe’s opening lever to open the sensor head. The UNLOCK indication is displayed
on the sensor head. Keep sliding the lever backwards into the Open position.

With the probe’s sensor head around the insulated conductor to be measured, slide the
opening lever of the probe
towards the front of the sensor head
into the
Lock

head is properly closed. If the sensor head is not closed properly, accurate measurements
will not be possible.
