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 that must be

followed to ensure safe operation as well as maintain the meter 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

must 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.
