CHAPTER 1 - OVERVIEW
A Brief Descripon of Chapter 1
This manual provides the user and service personnel with a descripon of the specicaons, installa-
on, setup, conguraon, operaon, communicaon, maintenance, and troubleshoong procedures
for the METRIX Instruments HI 803 Transducer Test Set (TTS). The HI 803 TTS is a totally self-contained
baery powered vibraon transducer tester. The TTS can be used in the eld or in the laboratory. The
TTS tests and veries the performance of most vibraon transducers including accelerometers, velocity
pickups and displacement probes. The TTS is also used to troubleshoot vibraon monitoring systems or
vibraon analyzers including cabling and associated system alarms and other instrumentaon.
About METRIX Manuals
Every METRIX Installaon and Operaon manual is organized into easily referenced chapters, that are
almost always the same:
• Chapter 1 - Provides an introducon to the instrument and an Overview of the equipment
and its capabilies.
• Chapter 2 - Provides a complete list of Specicaons.
• Chapter 3 - Contains informaon needed to Install the HI 803 TTS. (both standard and
oponal equipment)
• Chapter 4 - Provides all Calibraon instrucons.
• Chapter 5 - Pertains to the Operang Procedures of the HI 803 TTS.
METRIX Instruments hopes that this manual meets your needs for informaon and operaon. All cor-
recons or suggesons for improvements of this manual are welcome and can be sent to the Technical
Publicaons Department or Customer Support Department at METRIX Instruments Inc.
Descripon
The HI 803 TTS performs the following primary funcons:
1. Vibraon Generator “Shaker” - The vibraon generator is used to vibrate or “shake” the Transducer-
Under-Test (TUT). The frequency and amplitude of the applied vibraon are selectable and digitally
displayed. Operaon control is maintained and supervised by a microcomputer. A highly accurate refer-
ence accelerometer, which is traceable to the Naon Instute of Standards (NIST), is used to provide the
measurement signal, ensuring high accuracy of the displayed frequency and amplitude levels.
2. Automacally Calculates Transducer Sensivies - Internal elec- tronics provide the necessary signal
condioning and drive current for most transducers. By measuring the output signal of the TUT as it
is vibrated, and comparing it with an internal reference signal, the sensivity (signal out per unit of
moon) of the transducer is automacally calculated. This is calculated sensivity can then be used to
determine whether the TUT is within the transducer manufacturer’s specicaons. A thermal printer is
built in to the TTS to provide hard copy printouts of the test parameters and test results.
Capabilies
Amplitude Units
Vibraon amplitude units are selectable and displayed in acceleraon, velocity or
displacement. The units are also selectable in English or Metric.
Frequency Units
Vibraon frequency is displayed in hertz (Hz). Ranges are user selectable in 3-100 Hz, 100-
1000 Hz and 1000-10,000 Hz, with front panel selecons for 100, 1K and 10K respecvely.
Automac Calculaon
Sensivity calculaons (mV/engineering unit or pc/engineering unit) are automacally per-
formed using a microcomputer.
