Current Measurements

�
If tangible dangerous active parts are present in the plant where you
are making measurements, individual protection equipment (e.g.
suitable covers) must be used.
�
Always hold the instrument below the handle shroud.
�
The respective accident prevention regulations established by the
professional associations are to be strictly enforced at all times regarding
tasks executed under voltage or in proximity of parts under voltage.
1) Turn selector switch (2) to the AC current range you need
2) Open the clamp, and close it round the conductor. Make sure that the
clamp properly encircles the conductor, and that there is no air gap
between the jaws. For best measurement results and highest accuracy,
have the conductor placed in center of clamp jaws.

I + (- I) = 0
For incorrect measurement, the display equals zero. In compliance with
the Kirchhoff's current law states the sum of all currents equals zero.
However, this measurement layout in conjunction with a very sensitive
current clamp can be used to measure leakage currents.
