4. Total section thickness counter
Can also be set to ‘0’ at any time (via key).
If the total section thickness indication is not
set to ‘0’ manually, the instrument counts up to
maximum 9999.5 µm at which point the counter
will automatically switch back to ‘0’.
This indication shows the total thickness of all
sections carried out since the counter was last
