3. EC Declaration of Conformity

This is to certify that model DMM 190 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.

A. INTRODUCTION

INTRODUCTION

1. Congratulations!!

Thank you for purchasing a TPI Digital Multimeter. The Triple Display 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 meter 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, Inductance(Only192), continuity, Capacitance, Frequency, there is the adaptor function. The meter also has RS232 output and software for recording information into a PC.

The meter 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 meter comes complete with the following accessories:

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 meter 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 meter, 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.

2. Product Applications

Perform the following tests and/or measurements with the meter and the appropriate function:

HVAC/R DC mV • Gas application. ACA • Heat anticipator current in thermostats. ACV • Line voltage. ACV or DCV • Control circuit voltage. DcuA • Flame safeguard control current. OHMS • Heating element resistance (continuity). OHMS • Compressor winding resistance. OHMS • Contactor and relay coil resistance. OHMS • Continuity of wiring. Hz/FREQ • Frequency of line and control voltage. CAP • Motor start and run capacitance. REC • Record min/max voltage of controls and line

voltages.

ELECTRICAL ACV • Measure line voltage. OHMS • Continuity of circuit breakers. Hz/FREQ • Frequency of line and control voltage. DCV • Voltage of direct drive DC motors.

ELECTRONIC ACV • Measure power supply voltage. OHMS • Continuity of circuit breakers. REL% • Match components COMP • Compare readings in circuit or components Hz/FREQ • Frequency of line and control voltage.

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.
