This command draws a fixed hair cross in the centre of the image.Note: the program`s

function and results bars limit the image detail shown on the monitor. Depending on the

screen resolution (min 800 x 600) it may be that the whole of the live image cannot be

seen in the measurement program window. The fixed hair cross is always positioned centrally

to the image detail. When printing the image the hair cross may then again appear in

the centre of the full image.
