    Many other systems do not offer continuous time-domain transfer to the PC, and as a result the waveform length is limited by the amount of built-in data storage. In regard to our 652u, the only limitation is the amount of available hard disk memory on the host PC, or that which can be accessed by a PC on a network.

  • Page 11: Front Panel (Analog) Connectors

    The front panel includes ten BNC connectors for voltage input. These are labeled CH1 through CH10. The front panel also includes analog common. The IOtech 652u includes circuitry for dynamic analog signal conditioning. The circuitry typically interfaces with piezoelectric transducers that include, but are not limited to: accelerometers, microphones, tachometers, and force/pressure transducers.

    Refer to the specifications chapter for details, including a response chart. Analog Triggers The IOtech 652u signal analyzer can be triggered per software configuration relevant to the 10 analog input channels. Refer to the associated software documentation regarding the various types of triggers and how to set them.

    Asynchronously, the digital I/O can be either read or written to, as opposed to the synchronous mode, which is read- only. Points to note: To use the 652u’s Digital I/O, the host PC must have eZ-TOMAS software installed. All configurations pertaining to Digital I/O are controlled by software and can be updated by the software at any time.

When a computer has a board with USB 2.0 ports, an “Enhanced” USB controller can be found in the Device Manager. The Device Manager will also show two other USB controllers due to the fact that USB2.0 circuitry includes 3 chips [one for the actual USB2.0 capable devices and two for...

    This software adds real-time continuous and transient data acquisition to an IOtech 600 series system. Analysis can be in the time, frequency, or order domain.

  • Page 21: Ez-Tomas

    An IOtech 600 series system running with eZ-TOMAS can be easily moved from machine to machine with very short setup times. You can use the system to reduce downtime, improve data collection, troubleshoot, and recondition the machine.

  • Page 22: Ez-Balance

    Rotating Machine Balancing An IOtech 600 series system using eZ-Balance provides a solution for multi-plane field balance applications of rotating machinery. eZ-Balance computes the optimal balance weights and their locations, based on vibration data collected from the analyzer. The data is displayed in a convenient Polar plot that indicates the magnitude and phase of the unbalance as well as time and spectrum data.

    (non-destructive test) uses resonance to identify part variations caused by process inconsistencies and defects. Using eZ-NDT with an IOtech 600 series device is a fast and inexpensive method for performing 100% inspection of production parts. Inspection parts include, but are not limited to: powder metal, ceramics, and composites.
