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

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.
