(Clamp On)
2 or 4 traverses version
1. Fix a tensioning band for small or large nominal diameters as described on
Page 17. Do not fasten the second tensioning band. You must still be able to move
the second tensioning band along the pipe.
2. Determine the spacing between the distance holes (sensor distance).
!
Note!
To determine the spacing between the distance holes (sensor distance) use:
– the "Sensor Installation" Quick Setup menu if the measuring device has a local
operation. Use the Quick Setup as described on Page 82. The sensor distance is
shown in the POSITION SENSOR function (6886), (i.e. a letter between A...K for
sensor 1 and a number between 10...76 for sensor 2). The transmitter has to be
installed and connected to the power supply to carry out the "Sensor Installation"
Quick Setup.
– the procedure described on Page 86 ff. if the measuring device has no local
operation.
3. Place the mounting rail on the threaded studs and then fasten the second
tensioning band. Remove the mounting rail.

4. Fix the sensor holder to the pipe using the threaded studs. Tighten the locking nuts
using a spanner (AF 13).
5. Coat the contact surface of the sensors with an even (approx. 1 mm thick) layer of
coupling fluid (from the centre to the groove, see Page 117). Then carefully insert
the sensors into the sensor holder. Press the sensor cover onto the sensor holder
until you hear a click. Make sure that the arrows (
housing and sensor holder are pointing to each other. Then insert the sensor cable
plug into the opening provided and manually tighten the plug to the stop.
