Electrode installation and measuring cable connection

Measuring cable connection

The pH and redox electrodes are connected
using special terminated and shielded
multi-core cables.
The measuring cables (see table) can be
extended with junction box VBA or VBM (see
chpt. 9). Termination instructions are supplied
with the measuring cables.

Note:

Connectors, cable ends and
terminals are to be protected against
moisture to prevent inaccurate
measurement!
