7. Setting up the instrument
Trimming mode (TRIM/µm)
In the trimming mode, the coarse feed buttons
perform the so-called TRIM-STEP function.
When pressing a coarse feed button, a de-
fined, step-by-step advance (TRIM-STEP) by
the value selected in the LED TRIM/µm dis-
play and in the direction of the selected coarse
feed button.
When pressing a single-arrow coarse feed button,
a single TRIM-STEP takes place in the selected di-
rection.
When pressing one of the double-arrow coarse feed
buttons just briefly, there will also be a single TRIM-
STEP in the selected direction.
When holding down one of the double-arrow coarse
feed buttons, multiple consecutive TRIM-STEPs are
performed as long as the button is pressed.
Sectioning modes
Sectioning can be done either by the conventional
method of one full handwheel rotation per section or
in the rocking mode.
To activate the rocking mode, press
ROCK
.
The ROCK LED will be illuminated.
To section, rock the handwheel back and forth over
a short distance.
Every change of direction is electronically detected and
translated alternately into advance and retract move-
ments.
To deactivate the rocking mode, press ROCK again.
The ROCK LED will be extinguished.
The instrument can then again be used in the conven-
tional full-rotation mode.
