  • Page 32: Communications & Data Storage

    The SI7500 can communicate measuring results by means of printing, storing or transmitting data through its onboard USB, RS-232 and Parallel ports. This section details the setup options for the RS-232 and USB ports. For a full list of the available options and their implementation, please refer to the SI7500 User Manual (document number 502823).

  • Page 34: Usb Setup

    USB flash drive. Files stored on flash drives are named DataN.txt by the SI7500 system, where N denotes the number of the data file. File type: The USB port data file type can be specified to replace existing files (of the same name) on the USB flash drive, append to the existing file or create new files that are auto-numbered sequentially in ascending order (Data1.txt, Data2.txt..DataN.txt).

  • Page 35: Backing Up

    It is recommended that after satisfactory configuration of the SI7500, a backup copy of the settings be taken. This can be done by saving the SI7500 settings as a file onto a USB flash memory stick. The settings can later be copied onto the same or another SI7500 to refresh a configuration or to speed the installation procedure in applications using several units.

  • Page 36: Operation

    6.1 Basic Operation The SI7500 is ideally used for static gauging, where parts are measured at rest. The gauging process itself can be semi or fully automated to varying degrees, as required. The flow chart below details a standard SI7500 measurement process: 6.2 Selecting A Part...

  • Page 37: Establishing A Measurement Reference

    6.3 Establishing A Measurement Reference Since all Orbit modules (with the exception of Analogue Input Modules) are pre-calibrated, typically only a single point needs to be calibrated on the SI7500 to define a reference position. Analogue Input Modules however require a full calibration to be performed by the SI7500 to derive the resolution of the instrument to which they are connected, instructions for this procedure can be found in chapter 5 of the SI7500 User Manual (document number 502823).

  • Page 38: Conduct A Measurement

    6.4 Conduct A Measurement The SI7500's DRO and Bar Graph screens display continuously updating Dimension values. The instrument is designed such that once a part is in place and Orbit Digital probes or other modules are reading appropriately, the currently displayed reading can be 'captured' and saved into the instrument's internal memory.

  • Page 39: Send Or Report Results

    6.6 Send Or Report Results Reports of current dimension values, screen views, stored measurement results or even SI7500 setup parameters can be printed, transmitted to a PC or PLC or saved to a USB flash memory stick simply by displaying the desired screen and pressing the "Print" key.
