N2893A Probe
WARNING
The sensor head is a precision assembly including a molded component, a ferrite core, and a Hall
effect element. It may be damaged if subjected to sudden changes in ambient temperature, or
mechanical strain or shock, and therefore great care should be exercised in handling it.
WARNING
To avoid scratching the surfaces of the Hall effect elements, keep the core section of the sensor
closed, except when clamping it around the insulated conductor to be measured.
WARNING
Before turning on the instrument, you must connect the protective earth terminal of the instrument to
the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket
outlet provided with a protective earth contact. You must not negate the protective action by using an
extension cord (power cable) without a protective conductor (grounding).
