Procedure:

1. Plug the instrument to an ac supply.

2. Put the frequency selector switch to needed frequency (say 1000 Hz).

3. Set the mode selector on CAL and set the range selector on the desired setting example for 2, 20 or 200. The above refer to the full scale meter value in milli Siemens (mS). Along with the help of sensitivity knob keep the pointer roughly midway between the lowest and highest sensitivity say at 1 position.

4. Connect the conductivity cell electrodes to the suitable terminals of the instrument. Clean the conductivity cell along with distilled water (Conductivity water).

5. Take the standard KCl solution (say 0.1M) in a clean beaker.  Begin a stirring rod (to be used for magnetic stirring) within the solution and put the solution beaker on a magnetic stirrer plate.

6. Insert the conductivity cell in the solution.  Ensure that the platinum plate electrodes are completely immersed in the solution and they do not touch the stirring rod or the sides or the bottom of the beaker.
