We recommend that you position the device so that the device faces the tester in the 0° position. The gap in the center of the base plate is 3 cm in diameter. A scale is drawn on the plate to facilitate this. We recommend that you position the device so that the center of its screen is concentric with the base plate this will make alignment easier in many cases. The PT3 has four locks to fix the DUT into the housing.

Shown in Figure 6.īasic Usage Place the DUT into the housing The Carriage is the metal piece that holds the actuators. The R1 Axis is also referred to as the rotational stage.Īn Actuator is a finger-like module used to deliver a touch to the screen. The R2 Axis is also referred to as the base plate. The following images show the terminology and visual orientation of the PT3 that is referenced in this topic. You must practice and prepare to become comfortable using the PT3. The PT3 does all of these tasks well, but its capable performance does not make these tasks trivial. It can tap precisely at a defined point, realign quickly, perfectly trace up to five straight lines simultaneously, draw fixed-radius curves, and support adjustable distances between adjacent contacts. It can operate at performance levels where human operator precision is not sufficient. The Precision Touch Testing Tool, or PT3, is a multi-function tool that tests high-performance touch digitizers against the Windows Hardware Lab Kit touch tests for Windows 8.
