A. INTRODUCTION
1. Congratulations!!
Thank you for purchasing TPI products. The 265 is easy
to use and is built to last. It is backed by a 3 year limited warranty. Please remember to complete and return
your product warranty registration card.
2. Product Description
The 265 is a hand-held, autoranging clamp-on DMM.
Extra large numerals, capacitance, frequency and data
hold are just a few of the features of the 265. An
affordable choice, the 265 offers measurements in all
basic electrical functions.
The 265 comes complete with the following accessories:
Carrying Pouch
Test Lead Set
Instruction Manual

3. EC Declaration of Conformity
This is to certify that TPI Model 265 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 instrument must be operated in accordance with the instructions 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 transceivers, radio and TV transmitters, vehicle radios and
cellular phones generate electromagnetic radiation
that could be induced into the test leads of this instrument. 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 procedures whenever possible. Do not attempt to measure
unknown voltages or components until a complete
understanding of the circuit is obtained.

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 265 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 265, then to circuit being measured.
NEVER
• Attempt to measure unknown high voltages.
• Attempt to measure DC microamps 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.
