CONNECTING TO THE CIRCUIT TO BE
MEASURED
Open the probe coupling and slip the measuring head over the
conductor carrying the current to be measured.
Close the probe coupling such that it visibly and audibly snaps
into place.
An accurate measurement is assured under the following
conditions:
– The conductor is centered within the measuring head.
– The measuring head forms a perfect circle.
– The probe coupling is not located close to other conductors
carrying high current.
It is strongly recommended to de-energize the circuits to
be measured when making connections to the
installation. If it is necessary to make connections on
energized circuits they must be made by qualified and
authorized personnel only observing the required safety
precautions..
Never apply the probe around bare conductors with
voltage levels over 1000V (CAT III) or 600V (CAT IV) to
ground.
Always connect electronics unit to measuring device
before installing the flexible measuring head.
