Power Requirements
The oscilloscope operates from a 115 V (90 to 132 V) or 220 V (180 to 250 V) AC
power source at 45 Hz to 66 Hz. No voltage selection is required, since the instrument
automatically adapts to the line voltage present.
The power supply of the oscilloscope is protected against short-circuit and
overload by means of a 10.0 A/250 V AC, âTâ rated fuses (size: 5 X 20 mm),
located above the mains plug. Disconnect the power cord before inspecting or
replacing a fuse. Open the fuse box by inserting a small screwdriver into the
slot and turning counter clockwise.
For continued fire protection at all line voltages, replace only with fuse of the
specified type and rating (T 10.0 A/250 V).
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 oscilloscope. 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.
