The oscilloscope has not been designed to make direct measurements on the
human body. Users who connect a LeCroy oscilloscope directly to a person do so at
their own risk. Use only indoors.
Power Requirements
The oscilloscope operates from 90–132 V AC 45-440 Hz, and 180–250 V AC; 45–66
Hz. No voltage selection is required, since the instrument automatically adapts to
the line voltage present.
Fuses
The power supply of the oscilloscope is protected against short-circuit and overload
by means of two 6.3 A/250 V AC
“T”-rated fuses, located above the mains plug.
Disconnect the power cord before inspecting or replacing a fuse. Open the fuse box
by inserting a small screwdriver under the plastic cover and prying it open. For
continued fire protection at all line voltages, replace only with fuses of the specified
type and rating (see above).
Ground
The oscilloscope has been designed to operate from a single-phase power source,
with one of the current-carrying conductors (neutral conductor) at ground (earth)
potential. Maintain the ground line to avoid an electric shock.
None of the current-carrying conductors may exceed 250 V rms with respect to
ground potential. The oscilloscope is provided with a three-wire electrical cord
containing a three-terminal polarized plug for mains voltage and safety ground
connection. The plug's ground terminal is connected directly to the frame of the unit.
For adequate protection against electrical hazard, this plug must be inserted into a
mating outlet containing a safety ground contact.
Cleaning and Maintenance
Maintenance and repairs should be carried out exclusively by a LeCroy technician.
Cleaning should be limited to the exterior of the instrument only, using a damp, soft
cloth. Do not use chemicals or abrasive elements. Under no circumstances should
moisture be allowed to penetrate the disk drive analyzer. To avoid electric shocks,
disconnect the instrument from the power supply before cleaning.
CAUTION
Risk of electrical shock: No user-serviceable parts inside. Leave repair to
qualified personnel.
