Frequently asked Questions

  • Base Alignments
    • How does Auto Feature Recognition work?

      CALYPSO will automatically construct a feature out of the measured data. For instance, with one probing point, CALYPSO can construct a point. With a second point it can construct a line or a symmetry point. With a third point, CALYPSO can construct a plane or a circle.

    • How do I change my Base Alignment?

      On the Measurement tab, Click on Base/Start Alignment, then select “Change current base alignment”. You can make changes here and all your nominal values will automatically update to the new alignment. You can also make changes to the individual features in a Base Alignment and all the nominals for all the features will update.

    • When and how can I use Secondary alignments?

      You can use Secondary Alignments to match Datum Reference Frames. You can also, use Secondary Alignments when features on a Part Print are dimensioned from more than one origin.

  • Probe Qualification
    • What is Tensor Qualification?

      Tensor is the qualification method for Active Scanning head that take 2 points at 15 different locations on the Reference Sphere. The first point is taken with a low measurement force, the second with a high measurement force. The difference between the two point is captured and used to calculate the amount of stylus bend.

    • What is Dynamic Tensor Qualification?

      This is an enhanced Tensor Qualification routine, utilizing  circular scans at low and high measurement forces and slow and fact measurement speeds. This routine is absolutely required for the Navigator option and requires 180 degrees of sphere coverage.

    • What is Qualify Passive qualification?

      This is the only qualification routine available for the XXT TL1, TL2, or TL3 when qualifying a new stylus system or a new stylus on an existing stylus system.  It uses a series of circular scans on the Reference Sphere at low and high forces and slow and fast speeds to calculate bend. Then a six point routine to calculate size and location of the stylus sphere.  This initial routine requires 180 degrees of sphere coverage.

    • What is Geometry Requalification?

      This routine is available for the XXT TL1, TL2, or TL3 after the initial Qualify Passive routine has been run. It is simply the 6 point qualification that calculates size and location of the stylus sphere.

    • How often do I need to run Fitting Position?

      Fitting Position is the qualification routine for determining location of the operating sphere for the Master Probe with RDS-CAA. This location needs to be re-determined every time the RDS head is removed and reinstalled. Also, this can be done whenever the machined is homed.

      • The minimum screen resolution is 1280x1024 pixels. This is the default size for the 'CALYPSO User Desk' window.
      • Two network connections must be possible (incl. installed driver): 1x for control connection, 1x for customer network. The TCP/IP network protocol must be installed. 
      • The installed graphics card must be installed with CALYPSO OPEN-GL drivers. At least one of the ZEISS approved graphics cards should be used (NVIDIA Quadro FX 3800, NVIDIA Quadro2000 or ATI FirePro V3800).
      • Windows 7 32bit, Windows 7 64bit, or Windows 8.1 64bit
    • The CMM's drives are not moving and seem to be off. How do I turn on the drives?

      There are a few simple reasons why the drives may not be on and some easy solutions to resolve the issue.

      1. The first step is to cycle the power for both the CMM and the CMM’s computer by turning them off, then on.
      2. If they do not turn on, check the incoming air pressure. This is the most common issue. Sufficient pressure is needed, with a minimum of 6.2 bar (90 PSI) at the wall or connector location. The compressed-air connection on the CMM should be 5 bar (72.5 PSI).
      3. If the problem persists, consider the following in this order:
        • Be sure that the CMM is inside the measuring volume (not at the end of travel in the X, Y, or Z axes).
          Please follow the “Probe outside the measuring volume” section in the Operating instructions for specific steps to move the CMM back into the measuring volume.
        • The EMERGENCY STOP button on either the control console or control cabinet (not present on all CMMs) should be unlocked.
          Slightly turn the button to reset. The button will pop out a few millimeters.
        • If the control console LED lights are blinking and the display (on some models) shows a ZEISS logo, the control cabinet is off and needs to be turned on.
    • How do I properly shut down the CMM?

      Because the probe loses its reference to the CMM home position from its current location, use the following shut-down procedure to eliminate any potential issues when you turn it on.

      1. Move the probe to a safe position inside the measuring volume, close to but NOT in the home position.
      2. Move the probe holder to its initial position. If you have an articulating head, turn it to the 0/0 position.
      3. Close the measuring software.
      4. Shut down the operating system.
      5. Switch the computer off.
      6. Turn the drives off by pressing the Power M key on Control console panel. They are off when the LED above the key is not lit.
