You may notice that the touch screen on the tester is registering an incorrect location. This issue can be confirmed on the tester by selecting a point on an AirMapper survey and seeing if the point location is at the same point that the screen was touched. If they are noticeably different, a manual calibration process can be performed to improve the touch accuracy. Please contact us for instructions on how to perform a manual calibration.
Note: If new software is loaded onto the tester or factory defaults are restored, the manual calibration must be performed again.
