USER MANUAL
Safety Summary
The following safety precautions apply to both operating and
maintenance personnel and must be observed during all phases of
operation, service, and repair of this instrument. Before applying
power, follow the installation instructions and become familiar
with the operating instructions for this instrument.
If this device is damaged or something is missing, contact the
place of purchase immediately.
This manual contains information and warnings must be followed
to ensure safe operation as well as to maintain the oscilloscope in a
safe condition.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet
must be connected to an electrical ground. This instrument is
grounded through the ground conductor of the supplied, three-
conductor ac power cable. The power cable must be plugged into
an approved three-conductor electrical outlet. Do not alter the
ground connection. Without the protective ground connection, all
accessible conductive parts (including control knobs) can render
an electric shock. The power jack and mating plug of the power
cable meet IEC safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases
or fumes. Operation of any electrical instrument in such an
environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating personnel.
Component replacement and internal adjustments must be made
by qualified maintenance personnel. Disconnect the power cord
before removing the instrument covers and replacing components.
Under certain conditions, even with the power cable removed,
dangerous voltages may exist. To avoid injuries, always
disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
3
Do not attempt any internal service or adjustment unless another
person, capable of rendering first aid and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT
Do not install substitute parts or perform any unauthorized
modifications to this instrument. Return the instrument to B&K
Precision for service and repair to ensure that safety features are
maintained.
WARNINGS AND CAUTIONS
WARNING
and
CAUTION
statements, such as the following
examples, denote a hazard and appear throughout this manual.
Follow all instructions contained in these statements.
A
WARNING
statement calls attention to an operating procedure,
practice, or condition, which, if not followed correctly, could
result in injury or death to personnel.
A
CAUTION
statement calls attention to an operating procedure,
practice, or condition, which, if not followed correctly, could
result in damage to or destruction of part or all of the product.
WARNING:
Do not alter the ground connection. Without the
protective ground connection, all accessible
conductive parts (including control knobs) can
render an electric shock. The power jack and
mating plug of the power cable meet IEC safety
standards.
To avoid electrical shock hazard, disconnect power
cord before removing covers. Refer servicing to
qualified personnel.
Before connecting the line cord to the AC mains,
check the rear panel AC line voltage indicator.
Applying a line voltage other than the indicated
voltage can destroy the AC line fuses.
For
continued fire protection, replace fuses only with
those of the specified voltage and current ratings.
This product uses components which can be
damaged by electro-static discharge (ESD). To
avoid damage, be sure to follow proper procedures
for handling, storing and transporting parts and
subassemblies which contain ESD-sensitive
components.
