SA ArmPad

The SA ArmPad is a patent-pending input method that takes advantage of a calibrated pad (like a mouse pad) that can be placed on any work surface. Once calibrated, you can tap any function on the pad with a probing device, instantly performing an action or entering the selected measurement mode. You can then perform various interactive actions with SA without using the computer or setting down the arm / probe.

By measuring three calibration points (A, B, & C below), SA will recog- nize the position and orientation of the pad, as well as which pad is being used. (Multiple variations of ArmPads, each with different functionality, are possible). As long as the pad is not moved relative to the instrument, its functions can be activated.


Calibrating the ArmPad is a straightforward process. It only needs to be performed once for a given instrument/pad orientation. That is, as long as the relative position between the instrument and the pad re- main fixed, there is no need to recalibrate. Calibration results are stored with the instrument interface persistence files, so if an inter- face is shut down and restarted, the calibration is stored and recalled.

 

To Calibrate the ArmPad:

  1. In the instrument interface (but without any measurement modes active), click the SA ArmPad button , or hold button 2 on the arm for a brief moment.

  1. The ArmPad Calibration dialog will appear . Follow the prompts and touch the probe to each calibration point on the pad, measuring a single point at each.

 

Contact NRK Support to request a free pad. Or, click the Print Pad but- ton to bring up a PDF of the pad which you can print out yourself on a letter-sized sheet of paper to use. (Note that the PDF should be printed at full scale, ensuring Page Scaling is set to NONE.

The Cancel and Done buttons have various uses (which are intuitive) based on context--they are equivalent to the Cancel or Accept but- tons on the arm itself. The Prev and Next buttons have several meanings depending on context as well. For example, they switch to the previous or next feature when performing a GD&T Inspection, and they move to the previous or next relationship when trapping measurements.
