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

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.

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 procedures

for handling, storing and transporting parts and

subassemblies which contain ESD

sensitive

components.

Compliance Statements

Disposal of Old Electrical & Electronic Equipment (Applicable in the

European

Union and other European countries with separate collection systems)

Safety Symbols

This symbol is used to denote the measurement ground

connection.

This symbol on an instrument indicates caution. For details,

the user should refer to the operating instructions in the

manual.

Electrical Shock hazard.

On (Power). This is the In position of the power switch

when instrument is ON.

Off (Power). This is the Out position of the power switch

when instrument is OFF.

This symbol shows that the switch is a power switch located

at the top of the oscilloscope. Pressing this button toggles the

oscilloscope’s state between operation and power off mode.

CAT I

(400V)

IEC Measurement Category I.

Inputs may be connected to

mains (up to 400 VAC) under

Category I overvoltage conditions.
