40 Instructions for Use V 1.4 RevC – 09/2013
The deviation of the height amplitude is shown
on the display in µm (1). This value can be ei-
ther positive or negative. A number (e.g. –0.3)
appears in the ∑µm display (2). This means a
counterclockwise rotation (because of the "-")
by a turn of 0.3 and reduces the height ampli-
tude to a minimum. (If there is no operation
sign, the rotation is in a clockwise direction
"+".) If the value is "0", no improvement of the
height amplitude is possible.

7. If the measured value is accepted, press
DOWN (flashes green). VC moves to lowest
position - blade is moved to the rear. Control
panel of the VT shows: "VIBRO END". The LED
on the VC is again illuminated in red.
8. The instrument now expects the VibroCheck
to be removed. To do so, disconnect the USB
plug connection of the VC to the basic instru-
ment and pull the VC off of the dovetail guide.
LED in DOWN key continues to flash – wait
until LED in DOWN button goes out.
The normal operating status is now restored.

5. Press the STOP key. Unscrew the clamping
screw (16) only slightly using the size 3 Allen
key, pull the cap (17) up and off (keep it in a
safe place) and turn the adjusting screw (18)
counterclockwise (the "-" direction, 18a) by a
turn of 0.3 using the size 3 Allen key. Tighten
the clamping screw (16) clockwise.
6. Press the RUN key, check the value, repeat
steps 5-7 if necessary.

If the display shows ∑µm (2) "0" (opti-
mal) and the value in µm (1) is unaccept-
ably high, the blade must be replaced.
