9.6 Exchanging the cable/rod
If necessary, the cable or rod (measuring part) of the probe can be
exchanged.
Loosen the rod or cable with a fork wrench, wrench size 7 (rod ø 8,
cable ø 2 and 4) or wrench size 10 (rod ø 12).
1. Loosen the rod or cable with a fork wrench applied to the flat
surface, provide counterforce with another fork wrench.
2. Unscrew the loosened rod or cable manually.
3. Insert the new measuring rod carefully by hand with a twisting
motion into the opening of the process fitting.
4. Continue screwing in the rod manually into the opening of the pro-
cess fitting.
5. Exert counterforce with the second fork spanner and tighten the
rod or cable on the flat surfaces with the following torque.
Rod ø 8, cable ø 2 and 4: 6 Nm (4.43 lbf ft)
Rod ø 12: 10 Nm (7.37 lbf ft)
Fig. 35: Exchange cable or rod
Information:
Please keep the stated torque so that the max. tensile strength
remains.
6. Enter new probe length and then carry out a fresh adjustment
(see "Setup procedure, Carrying out min. adjustment - Carrying
out max. adjustment").
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.
