Safe Probing - Keysight N2780B User Manual

Safe Probing

This device is designed to comply with IEC 61010 Safety Standards, and has been
thoroughly tested for safety prior to shipment. However, mishandling during use
could result in injury or death, as well as damage to the device. Be certain that you
understand the instructions and precautions in the manual before use. We
disclaim any responsibility for accidents or injuries not resulting directly from
device defects.
To avoid short circuits and potentially life-threatening hazards, follow these
warnings and precautions:
N2780/1/2/3B User's Guide
WARNING To prevent fire or damage of the measurement target and device as well
as burns, exercise caution concerning the following when measuring
high-frequency currents or currents that contain high-frequency
components:
•Eddy current loss may cause heating of the sensor head.
•Dielectric heating may cause heating of cord insulation and other
materials.
•This device should only be connected to the secondary side of a
breaker, so the breaker can prevent an accident if a short circuit
occurs. Connections should never be made to the primary side of a
breaker, because unrestricted current flow could cause a serious
accident if a short circuit occurs.
WARNING For safety's sake, avoid clamping around bare conductors while
clamping or measuring.
WARNING Take measurements at a location on an insulated wire where there is
sufficient insulation for the circuit voltage.
WARNING Be careful to avoid damaging the insulation surface while taking
measurements.
WARNING Do not allow the device to get wet, and do not take measurements with
wet hands. This may cause an electric shock.
