Getting started
To ensure stable positioning, the instrument is
equipped with 3 trigger pins on the bottom plate. If
not all pins have been pressed thoroughly on the
sample surface (e.g. curvature too high, instrument
movement), the display shows the pins which are
not pressed correctly in red and the indication
lights are red.
Press all pins correctly on the sample surface. The
pins on the display and the indication lights turn
green.
