Leica Leica VT1200S manual Operating the VibroCheck, Using the VibroCheck with the VT1200

6. Operating the VibroCheck

6.1Using the VibroCheck with the VT1200

The following instructions must be adhered to exactly. Noncompliance can cause serious damage to the instrument.

We recommend using the VibroCheck after each blade change to check the optimum position of the blade and minimize the vertical vibration.

Prior to assembly, the dovetail guide (3) is brought down to the lowest position using the DOWN key!

1.The user installs the VibroCheck: the VC is pushed along the dovetail guide (3) past the mark on the base plate of the instrument (rear stop) and clamped firmly using the lever (15). Insert the blade and clamp tightly. Return the blade to the cutting position (see Fig. 20).

2. Plug the connecting plug of the VibroCheck (VC) into the socket (2) on the left side panel. Short red flash of LED on VC --> control panel acknowledges VC. LED then remains red. LED in DOWN key flashes green.

3.The user presses the DOWN key. The VC moves to the bottom position, after that the blade moves to the rearmost position – the LED in the RUN/STOP key flashes. Short red flash of LED on VC --> it then remains red.

4. The user presses the RUN/STOP key: the blade first moves towards the front (into the posi- tion exactly above the VibroCheck); the VC then moves into a position in which the blade partly covers the light barrier. (If the VC does not receive any signal via the light barrier, the operation is canceled and DOWN is enabled.) LED on VC flashes green – RUN/STOP flashes yellow.
