A. INTRODUCTION
1. Congratulations!!
Thank you for purchasing a TPI Digital Multimeter. The
Triple Display 183 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. The 183 is covered by a 3 Year Limited Warranty.
2. Product Description
The 183 is a hand-held autoranging DMM. The backlit LCD
can display three readings at one time. In addition to basic
functions of ACV, DCV, ACA, DCA, , Diode Test and
Continuity, the 183 measures Frequency (Hz) and
Capacitance. The 183 also has RS232 output and software
for recording information into a PC.
The 183 also features:
• REC Records Min/Max and Average readings during
specified measurement intervals. Time reference can also be displayed to determine when
the values were recorded.
• COMP Compare actual reading to preset HI and LOW
values for Pass/Fail testing of components.
• HOLD Two-hold system automatically holds the
previous stable reading when a new one is
obtained.
The 183 comes complete with the following
accessories:
Battery
Rubber Boot
Test Lead Set
Instruction Manual
3. EC Declaration of Conformity
This is to certify that model 183 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
ALWAYS
• Test the 183 before using 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 183, and 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.

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-sinu-
soidal AC voltage and current waveforms
found on many controls and circuits.
Triple Display Shows more than one reading simultaneously.
Analog Bar Shows rapidly changing input signals
Graph that the normal display will not.
Two-Hold Holds two readings on the display at
System the same time.
Auto Off Automatically powers instrument off after 30
minutes of inactivity. Pressing any push
button or turning the rotary switch returns
the 183 to normal.
Record Records Min/Max and Average values. Time
reference when value was obtained.
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.
Autorange Automatically selects the best range for
the measurement.
