Where can I find Fixturlaser Dials app?

The app is available free of charge from both App Store and Google Play. It works on full size tablets as well as iPhone and Android phones. There are currently no version available for Windows Mobile phones.



I have a different fixture setup, can I use the app?

  • The app can be used if you are using the reversed rim method. As the app is currently designed it only supports the setup where both dials are on the same side of the shaft.
  • If you have a setup where the dials are on the opposite side of the shaft, you can still use the app to help you with the calculations BUT you will need to reverse the sign of the numbers you read off the dial sitting on the opposite side from what the app is showing you. I.e. if the M dial is positioned at 6 o’clock, while the app shows it to be at 12 o’clock, and the dial is pointing at 30 you will need to enter -30 in the app.

I get the an offset error of 4.5 – Is that in Inch??

  • When you work with the app set in imperial measures (inch) we express the angular error as mils/inch, or thousands of an inch/inch and the offset error as mils, or thousands of and inch.
  • 1 mils, or 1 thou = 0.001 inch
  • This can be confusing, especially if you are in a company where you have a mix of imperial and metric dimensions. Using the therm ‘mils’ can easily be perceived as an abbreviation for millimeter. This can cause major problems. So be careful how you express yourself. 🙂

What does the angular error mean?

  • The angular error is expressed as mm/100mm. We call it a measure of slope or rise-over-run. (Check out this video)
  • You can also see it as a measure of coupling gap.
    • Example: If you have an angular result of -0.4mm/100mm you can see it as a coupling gap of 0,4mm if the coupling diameter is 100mm. The minus (-) sign means that the gap is on the top of the coupling, at the 12 o’clock position.

My measurement data is not saved

  • As default, the app will automatically try to save the measurement result as an image to your camera roll on your device. On iOS you must allow the app to access your photos. this question comes up on your screen the first time you use the app.
  • There is also a check box in the app’s tools menu (checked by default) that needs to be checked to automatically save the measurement.
  • If your data isn’t saved; make sure the checkbox is marked in the app’s tools menu and check that the app has access to your photos in your device’s Settings screen.

I have a problem but cannot find the answer here.
