Cable capacity

Page 70
A cable of a given length has a given capacity. When the measured
conductance is low (below 4 µS), the cable capacity is not
negligible and must be taken into account.
Enter the cable capacitance when:
• measuring low conductances (below 4 µS),
• the cable capacity of the conductivity cell is greater than 350 pF.
The cable capacity is normally specified by the manufacturer. Cable
capacities of a few Radiometer Analytical conductivity cells are given

If you create a conductivity cell from the Catalogue list, the
cable capacity is automatically assigned to the
conductivity cell created (and cannot be modified).
