Use the constant CURRENT setting of the supply.

A slight flaw in what is causing what. The acid concentration has a direct effect on the level of voltage as it is part of the resistance in the circuit. Ohm's law dictates that. The real reason for a PS to max out using the numbers you gave in the example is that you are running the part at a 14 ASF current density.
