4. Stirring may be necessary for highest accuracy measurements, especially in low-conductivity
solutions.
5. If possible, isolate from ground potential the container or system in which measurements are to
be made.
6. Electrical fields and stray currents caused by stirrer motors, heaters, etc., can interfere with
measurements. The user should determine the effects of these and make the necessary
corrections, either by shielding or by disconnecting those units that cause trouble.
7. Always rinse the cell carefully before transferring it from one solution to another.
8. Never store a dirty or contaminated cell.
