Getting Started
Do not install substitute parts or perform any unauthorized modification to the
WARNING
probe.
Do not operate the probe or oscilloscope in the presence of flammable gasses or
WARNING
fumes. Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
If the probe is used in a manner not specified by the manufacturer, the protection
WARNING
provided by the probe assembly may be impaired.
Do not attempt internal service or adjustment. Service should be carried out by a
WARNING
Keysight Technologies authorized service personnel. For any service needs, contact
Keysight Technologies.
The probe cable is a sensitive part of the probe and, therefore, you should be careful
CAUTION
not to damage it through excessive bending or pulling. Avoid any mechanical shocks
to this product in order to guarantee accurate performance and protection.
Concerning the Oscilloscope or Voltage Measuring Instrument to Which
the Probe is Connected
Whenever it is likely that the ground protection is impaired, you must make the
WARNING
instrument inoperative and secure it against any unintended operation.
If you energize the instrument by an auto transformer (for voltage reduction or
WARNING
mains isolation), the ground pin of the input connector terminal must be connected
to the earth terminal of the power source.
Before turning on the instrument, you must connect the protective earth terminal of
WARNING
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). Grounding one conductor
of a two-conductor outlet is not sufficient protection.
Capacitors inside the instrument may retain a charge even if the instrument is
WARNING
disconnected from its source of supply.
