Safety Summary

The following safety precautions apply to both operating and maintenance personnel and must be followed during all

phases of operation, service, and repair of this instrument.

Before applying power to this instrument:

• Read and understand the safety and operational information in this manual.

• Apply all the listed safety precautions.

• Verify that the voltage selector at the line power cord input is set to the correct line voltage. Operating the instrument

at an incorrect line voltage will void the warranty.

The IEC 61010 standard denes safety category ratings that specify the amount of electrical energy available and the

voltage impulses that may occur on electrical conductors associated with these category ratings. The category rating is

a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of the circuit to be tested,

which denes the voltage impulses expected and required insulation clearances. These categories are:

Category I (CAT I): Measurement instruments whose measurement inputs are not intended to be connected to the

mains supply. The voltages in the environment are typically derived from a limited-energy trans-

former or a battery.

Category II (CAT II): Measurement instruments whose measurement inputs are meant to be connected to the mains

supply at a standard wall outlet or similar sources. Example measurement environments are portable

tools and household appliances.

for this instrument.

You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the

instrument’s category rating to maintain the instrument’s category rating. Failure to do so will lower the category rating

of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be

115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your

country of use.

Ground the Instrument

To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This

Unless otherwise stated, a ground connection on the instrument’s front or rear panel is for a reference of potential only

and is not to be used as a safety ground. Do not operate in an explosive or ammable atmosphere.

Do not operate the instrument in the presence of ammable gases or vapors, fumes, or nely-divided particulates.

The instrument is designed to be used in oce-type indoor environments. Do not operate the instrument

• In the presence of noxious, corrosive, or ammable fumes, gases, vapors, chemicals, or nely-divided particulates.

• In relative humidity conditions outside the instrument’s specications.

• In environments where there is a danger of any liquid being spilled on the instrument or where any liquid can condense

on the instrument.

• In air temperatures exceeding the specied operating temperatures.

• In atmospheric pressures outside the specied altitude limits or where the surrounding gas is not air.

rapid temperature or humidity changes, sunlight, vibration and/or mechanical shocks, acoustic noise, electrical noise,

strong electric elds, or strong magnetic elds.

Do not operate instrument if damaged

If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other material gets on or inside the

instrument, remove the instrument’s power cord, remove the instrument from service, label it as not to be operated,

and return the instrument to B&K Precision for repair. Notify B&K Precision of the nature of any contamination of the

instrument.

Clean the instrument only as instructed

Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants, solvents, acids/bases,

or other such chemicals. Clean the instrument only with a clean dry lint-free cloth or as instructed in this manual. Not

for critical applications

exist when the covers are removed. To avoid injuries, always disconnect the power cord from the instrument, disconnect

all other connections (for example, test leads, computer interface cables, etc.), discharge all circuits, and verify there

are no hazardous voltages present on any conductors by measurements with a properly-operating voltage-sensing device

before touching any internal parts. Verify the voltage-sensing device is working properly before and after making the

measurements by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt

any service or adjustment unless another person capable of rendering rst aid and resuscitation is present.

Do not insert any object into an instrument’s ventilation openings or other openings.

Hazardous voltages may be present in unexpected locations in circuitry being tested when a fault condition in the circuit

exists.

Fuse replacement must be done by qualied service-trained maintenance personnel who are aware of the instrument’s fuse

B&K Precision for service and repair to ensure that safety and performance features are maintained.

For continued safe use of the instrument

• Do not place heavy objects on the instrument.

• Do not obstruct cooling air ow to the instrument.

• Do not place a hot soldering iron on the instrument.

• Do not pull the instrument with the power cord, connected probe, or connected test lead.

• Do not move the instrument when a probe is connected to a circuit being tested.
