    METRIX Instruments HI 803 Transducer Test Set (TTS). The HI 803 TTS is a totally self-contained battery powered vibration transducer tester. The TTS can be used in the field or in the laboratory. The TTS tests and verifies the performance of most vibration transducers including accelerometers, velocity pickups and displacement probes.

  • Page 7: Phase

    (approximately .125 inch P-P dis- placement). Principles of Operation The HI 803 Transducer Test Set is comprised of a Signal Generator, Power Amplifier, Electro dynamic Vibrator, Reference Accelerometer, Digital Voltmeter, Microcomputer and Digital Indicator.

  • Page 8: The Signal Generator

    Capabilities (continued) The Signal Generator The signal generator produces a variable frequency sine wave which becomes the source of the driving signal to produce the vibration at the shaker head. The amplitude of this sine wave signal is controlled by the front panel AMPLITUDE dial controller. The frequency is also con trolled by the front panel FREQUENCY dial controller.
