Front Panel Key Test
Front Panel Key Test
Allows you to test the front panel keys of the instrument.
(Note: This is not available in A.15.xx software)
Front Panel Display Test
The display test will show 5 screens with colors: white, black, red, green, and
blue. This allows you to test for bad pixels in the display. After the last color,
the test will exit and results will be stored to the following log file:
C:\Temp\DisplayTestResults.txt
Multitouch Test
This test includes a series of simple tests to test the basic functionality of the
multi-touch screen. The test results will be stored to the following file:
C:\Temp\MultitouchTestResults.txt
Rotate Test
A Picture will appear in the center of the screen. Use two fingers to rotate the
image 45 degrees clockwise. Once this is completed, rotate the image 45
degrees counter-clockwise.
Zoom Test
A small picture will appear in the center of the screen. Use two fingers and
spread them apart to scale the box until it fills the dotted rectangle around it.
The dotted rectangle will resize. Pinch your fingers together to contract the box
until it fits inside the now smaller dotted rectangle.
Drag Test
A blue circle will appear in the center of the screen. Drag the circle into each
square of the gray grid on the screen to pass the test. Each square will be
colored green when it has been dragged over.
Accuracy Test
The screen will display a series of lines. For each blue line, trace along the line
with your finger to draw a matching line. Lines that deviate significantly from
the blue trace line (i.e beyond the gray lines) will be marked in red.
