If you are using glass electrodes with the panel-mounted instrument, you have to terminate
the measuring cable with a BNC connector. A solder-free BNC connector is supplied with the
device.
Proceed as follows:
1. Cut off end sleeves 2 and 3 of the coaxial
cable ( 
å
16).

4 Strand BN (PA)
2. Push the cable gland 5 and the washer 6
onto the coaxial cable.
3. Remove the insulation (13 mm(0.51"))
and screw the clamping ring 7 onto the
insulation.
Parts 5 to 7 are supplied with the BNC
connector for cable diameters 3.2 mm
(0.13") and 5 mm (0.20").
4. Fold the braided screen 8 over the
clamping ring and cut off the excess
material.
5. There is a semi-conductor layer 14
(conductive foil) between the inner
insulation and the braided screen 8. Strip
this semi-conductor layer to the braided
screen.

7. Position the end sleeve 13 onto the
stripped inner conductor and secure the
end sleeve with crimping pliers. a0005746

8. Push the BNC connector housing 9 over
the cable. The inner conductor must be
located on the clamping surface 10 of the
connector.
9. Tighten the cable gland 5.
10.Insert the clamp element 11 and screw in
the connector cover 12. This creates a safe
connection between the inner conductor
and the connector pin.
