Fig. 34: Exchange cable or rod
Information:
Please keep the stated torque so that the max. tensile strength
remains.
The rod or cable of the probe can be shortened individually.
1. Mark the requested length with mounted measuring rod.
2. Cable: Loosen the pins on the gravity weight (hexagon 3)
3. Cable: remove the pins
4. Cable: Pull the cable out of the gravity weight
5. Shorten the cable/rod with a cut-off wheel or metal saw at the
marking. Take note of the specifications in the following illustration
when shortening the cable.
6. Cable with gravity weight: Shift the cable according to the drawing
into the gravity weight
7. Cable with gravity weight: Fasten cable with the pins, torque 7 Nm
(5.16 lbf ft)
Cable with centering weight: Fasten cable with the pins, torque
7 Nm (5.16 lbf ft) and fix the clamping part on the centering
weight.
8. Enter new probe length and then carry out a fresh adjustment
(see "Setup procedure, Carrying out min. adjustment - Carrying
