the thickness in 1µm steps between 1 and 30µm (see section 2.3.1)
2.2.2 SPECIMEN TRAVEL
The vertical bar graph contains separate segments that light up sequentially as the
Specimen Head advances from its maximum available travel position. The proportion of
lit to unlit segments indicates the amount of travel still available at any time.

When the instrument is first powered up, the first segment flashes to indicate that the
Specimen Head is in its maximum available travel (MAX) position. As the Specimen
Head advances at the end of each cutting stroke, the segments of the display light one
by one until eventually all the segments are lit when no more travel is available. An
audible alarm operates when the end of travel is reached.
[E only]:
Press
[RESET] to return the Specimen Head to its maximum available travel position. The
button LED will light and the display will flash during the reset and the segments will count
down until the Specimen Head reaches maximum travel. The first segment will flash.
Note
1 When the instrument is being reset, all other advance or rewind functions are
over-ridden. This occurs each time the instrument is switched on, or [RESET] is
pressed.
2.2.3 TIME CONTROLS
The Time Controls allow you to set the clock time,
defrost times and fumigate times. Real time is
