Operating Manual V1.1 – 05/2007

When LED on VC is green and LED in RUN/

STOP is yellow, the blade starts to vibrate with

the amplitude set. Speed = 0, amplitude can

be changed at any time.

On the (5-digit) display, the deviation in height

amplitude is shown in μm (e.g. 0.9μm). This val-

ue can be either positive or negative. The dis-

play can be switched using the key μm/∑μm.

Then a number appears (e.g. 0.4). This means

clockwise rotation by 0.4 turns ("+" see 18a) –

(Neg. operational sign means counterclockwise

rotation – see 18a). If the value is "0", no improve-

ment of the height amplitude is possible.

5. Press the STOP key. Using a size 3 Allen key,

unscrew the clamping screw (16) only slightly,

pull off the cap (17) by pulling it upwards (keep

it in a safe place) and turn the adjusting screw

(18) by the corresponding value (here, 0.4 turns)

clockwise (in the "+" direction, 18a) using a size

3 Allen key. Tighten the clamping screw (16)

clockwise.

6. Press the RUN key, check the value, repeat

steps 5 – 7 if necessary.

7. If the measured value is accepted, press

DOWN (flashes green). VC moves to lowest

position – blade is moved to the rear. LED on

VC illuminates red again (LED on RUN/STOP

is off).

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.

If the display shows ∑μm (2) "0" (opti-

mal) and the value in μm (1) is unac-

ceptably high, the blade must be

replaced.
