B. SAFETY CONSIDERATIONS

WARNING: Please follow manufacturers test

procedures whenever possible. Do not attempt to

measure unknown voltages or components until a

complete understanding of the circuit is obtained.

GENERAL GUIDELINES

ALWAYS

• Test the 291 before using it to make sure it is

operating properly.

• Inspect the test leads before using to make sure there

are no breaks or shorts.

• Double check all connections before testing.

• Have someone check on you periodically if

working alone.

• Have a complete understanding of the circuit

being measured.

• Disconnect power to circuit, then connect test leads to

the 291, then to circuit being measured.

NEVER

• Attempt to measure unknown high voltages.

• Attempt to measure current with the meter in

parallel to the circuit.

• Connect the test leads to a live circuit before

setting up the instrument.

• Touch any exposed metal part of the test lead assembly.

3. EC Declaration of Conformity

This is to certify that TPI Model 291 conforms to the

protection requirements of the council directive

89/336/EEC, in the approximation of laws of the member

states relating to Electromagnetic compatibility and

73/23/EEC. The Low Voltage Directive by application of

the following standards:

EN 50081-1 1992 Emissions Standard

EN 50082-1 1992 Immunity Standard

EN 61010-1 1993 Safety Standard

EN 61010-2-031 1995 Safety Standard

EN 61010-2-032 1995 Safety Standard

To ensure conformity with these standard, this instru-

ment must be operated in accordance with the instruc-

tions and specifications given in this manual.

CAUTION: Even though this instrument complies with

the immunity standards, it’s accuracy can be affected

by strong radio emissions not covered in the above

standards. Sources such as hand-held radio trans-

ceivers, radio and TV transmitters, vehicle radios and

cellular phones generate electromagnetic radiation

that could be induced into the test leads of this instru-

ment. Care should be taken to avoid such situations or

alternatively, check to make sure that the instrument is

not being influence by these emissions.

CAUTION: Please follow manufacturers test proce-

dures whenever possible. Do not attempt to measure

unknown voltages or components until a complete

understanding of the circuit is obtained.
