I'm pretty sure your just looking for the pH of the cell. So you would use the concentrations to find [H+] and then use -log[H+] to find the pH.

A pH meter is a device used to measure the pH of a solution/system. So yes, it follows that the question you're referring to is wanting you to find the pH! It would help more if you would provide the question you're trying to answer.

A pH meter is an example of an ion-selective electrode. The pH meter has a thin-walled glass membrane that measures the difference in [H+] from in the standard inside the pH meter and the solution is is placed in. This [H+] difference is used to find the pH of the solution.
