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.
Failure to comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and intended use of the
instrument. B&K Precision assumes no liability for a customer’s failure to comply
with these requirements. This is a Safety Class I instrument.
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
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 protec
tive 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.
WARNING: To avoid electrical shock hazard, disconnect power cord
before
removing covers. Refer servicing to qualified personnel.
CAUTION:
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.
CAUTION:
This product uses components which can be damaged by
electro-
static discharge (ESD). To avoid damage, be sure to follow
proper pr
ocedures for handling, storing and transporting parts and
subassemblies which contain ESD-sensitive components.
