Not saying that you cannot make it work. However, a pure resistive load that will maintain that resistance under load is best for making accurate adjustments. A resistor dummy load can/will do that.

Heating the resistor will change its resistance value, the more power that is applied to it will change its value. Using a 100w dummy resistor in a can of mineral oil will keep it consistent; but this will also depend upon how much power is applied. More power means more heat and a larger range of error.
