A. INTRODUCTION

INTRODUCTION

1. Congratulations!!

Thank you for purchasing a TPI Digital Multimeter. The
Triple Display196 is an innovative new concept in DMM
design. The unique display enables you to view more than
one event at a time. This eliminates the hassle of switching
back and forth to review minimum, maximum or preset
comparative values. The meter is also easy to use and built
to last.

2. Production Description

The DMM 196 is a hand-held autoranging DMM. The backlit
LCD can display three readings at one time. In addition to
basic function of AC/DC V, AC/DC A, Ohm, Diode test,
continuity, Capacitance, Frequency, there is the adaptor
function. The DMM 196 also has RS232 output and software
for recording information into a PC.

The DMM 196 also features:

•

REC Records Min/Max and Average readings during

specified measurement intervals.

•

COMP Compare actual reading to preset HI and LOW

value for Pass/Fail testing of component.

•

HOLD Tow hold system automatically holds the previous

stable reading when a new one is obtained.

The DMM 196 comes complete with the following
accessories:

Battery
Rubber Boot
Test Lead Set

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 DMM 196 before using to make sure it is
operating property.

• 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 under test.

• Disconnect power to circuit, and then connect test leads to
the DMM 196, and then to circuit being measured.

NEVER

• Attempt to measure unknown high voltage.

• Attempt to measure current with the meter in parallel to
the circuit.

• Connect to 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 model DMM 196 conforms to the
protection requirement 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

To ensure conformity with these standards, this instruction
must be operated in accordance with the instruction 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
the 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.

C. TECHNICAL DATA

1. Features and benefits

Safety Meets CE and IEC 1010 requirements. UL

Listed to U.S. and Canadian Safety
Standards.

True RMS Needed to accurately measure non-

sinusoidal AC voltage and current
waveforms found on many controls and
circuits.

Triple Display Shows more than one reading

simultaneously.

Two-Hold Holds two readings on the display at
System thesame time.

Auto Power Off

Automatically powers instrument down
after 15 minutes of inactivity, yet will
continue acquiring data in its various
modes.

Record Records Min/Max and Average values

Compare Compares stored value with measured

value for matching components.

Relative Displays measured value as a % of stored
Percentage value for checking component tolerances.

RS232 Output Transfers data directly to a PC while

measuring.

Back Light Allows viewing in any light condition.

Auto range Automatically selects the best range for

the measurement.
