A. INTRODUCTION

1. Congratulations!!

Thank you for purchasing TPI brand products. The meter 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 163 is a hand-held autoranging DMM. The 163
measures ACV, DCV, ACA, DCA, Resistance, Diodes and
Continuity.

The 163 also features:

• RANGE Allows the user to manually range the

163 instead of autoranging.

• Data Hold Holds the reading on the display for

easy viewing.

• Auto Off Preserves battery life.

The 163 comes complete with the following accessories:

Rubber Boot
Test Lead Set
Instruction Manual
Battery

3. EC Declaration of Conformity

This is to certify that model 163 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
EN61010-1 1993 Safety Standard
EN61010-2-031 1995 Safety Standard

To ensure conformity with these standards, 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, the 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 influenced by these
emissions.

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

AL

WAYS

• Test the 163 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 complete understanding of circuit being
measured.

• Disconnect power to circuit, then connect test
leads to the 163, 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.
