surfaces dry and clean.
Do not operate in an explosive environment.
The intended use of these probes is for the measurement of AC current.
CAUTION
Keysight Technologies accepts no responsibility for any damage resulting
from careless use, or failure to observe these instructions.
If HAZARDOUS LIVE voltages are present and accessible in the installation,
WARNING
appropriate protective measures must be taken to avoid electric shock.
The integrity of the insulation around the Rogowski coil must be VISUALLY
WARNING
INSPECTED before and after each use, and the probe must NOT BE USED if
there are signs of coil damage.
Be extremely careful when using the coil of the probe on uninsulated
WARNING
conductors. The power of the uninsulated conductor must be turned off
when applying or removing the probe's coil from this conductor.
In addition, make sure that the probe is never used at voltages greater than
its voltage rating (safe PEAK working voltage) which is clearly labeled on
the probe cable adjacent to the coil. For N7040A and N7041A, it is 5kV peak
and for N7042A, it is 1.2kV peak.
Voltage ratings are only valid if the 'free end' of the coil is fully inserted into
the probe's ferule, and remains fully inserted during use. Refer to the topic
"Probe Handling Precautions" on page 16 to know more.
