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.
