WARNING
Do not operate the probe or oscilloscope in the presence of flammable gasses or
fumes. Operation of any electrical instrument in such an environment
constitutes a definite safety hazard.
WARNING
Do not use the probe or oscilloscope in a manner not specified by the
manufacturer.
WARNING
Service instructions are for trained service personnel. To avoid dangerous
electric shock, do not perform any service unless qualified to do so. Do not
attempt internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present.
Concerning the Oscilloscope or Voltage Measuring
Instrument to Which the Probe is Connected
WARNING
Whenever it is likely that the ground protection is impaired, you must make the
instrument inoperative and secure it against any unintended operation.
WARNING
If you energize the instrument by an auto transformer (for voltage reduction or
mains isolation), the ground pin of the input connector terminal must be
connected to the earth terminal of the power source.
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). Grounding one
conductor of a two-conductor outlet is not sufficient protection.
WARNING
Only fuses with the required rated current, voltage, and specified type (normal
blow, time delay, etc.) should be used. Do not use repaired fuses or
short-circuited fuseholders. To do so could cause a shock or fire hazard.
WARNING
Capacitors inside the instrument may retain a charge even if the instrument is
disconnected from its source of supply.
