4.9 Joystick calibration and test

Joystick calibration is process which allows correct operation of the device. Normally it is only done at the production stage and recalibration by the operator should never be necessary. If the joystick behaves incorrectly (if, for example, a pan or tilt direction stays active when the joystick is at rest) it may be necessary to carry out the calibration procedure.

First stage: with the joystick at rest (released) press . This

will specify the point at rest. Pressing will pass to testing without continuing with calibration.

After pressing , move the joystick without forcing it until it

reaches its maximum extension upwards, downwards, to the right and to the left.

During movement the values for certain readings will appear on the display. These are of no interest to the operator unless there is faulty operation, in which case they may be useful for telephone assistance. The joystick should be moved until the values given for , ,  and  (values that show the limit points to the left, right, bottom and top) do not change when the joystick is moved. The values shown in the centre of the display change continually when the joystick is moved.

Pressing will pass to the next stage of setup.

Pressing will pass to testing without completing calibration.

During normal operation, activation of the zoom will correspond to rotation of the joystick.

Rotate the joystick until the two extremes are reached several times, until the values shown by  and  (limit points for the counterclockwise and clockwise directions) do not change.

Pressing will complete setup and pass to testing, pressing

will pass to testing without recalibrating the zoom.

Joystick test: after calibration this enables the operator to check whether calibration was successful.

With the joystick at rest the values shown by ,  and  should be equal to 0. Move the joystick until the limit is reached in the four directions and rotate it to the limit in the clockwise and counter-clockwise directions. If, after these operations, the three  parameters and the three  parameters show  calibration was successful.

Otherwise it is advisable to recalibrate the joystick since a setup error in the joystick will affect its operation.
