Selecting 'TRACKER' transfers to the 'Tracker test.' screen. This invites a user to use a
tracker ball to test the interface, and reports on the screen the details of the last key to be
pressed, and the last movement of the ball:

The possible responses are shown on the diagram. Note that the center key on the tracker
has no function in its operation with the 9500B, and is not tested, so pressing this key
should have no effect, unless the tracker is defective.
If the last key to be named does not coincide with the last key to be physically pressed, or
if the last direction shown does not correspond to the last physical movement; then a
failure is implied. It is possible to diagnose the defect source by checking a second
tracker unit on the same 9500B, or the same tracker unit on a different 9500B.
Rectification may require access to the internal circuitry of the 9500B or tracker unit, so
no further user action is recommended, except to report the result to your Fluke
Calibration Service Center.
EXIT returns to the Interface 'Select test' menu screen.
Printer Checks
Checks of a connected printer are initiated by pressing the PRINTER key on the 'Select
test' menu screen.
Selecting 'PRINTER' transfers to the 'Printer test.' screen. This invites a user to use a
printer to test the interface (e.g. by switching the printer off-line, or removing the paper),
and reports on the status of the printer:
