What I do to put L/R 3 sec balance on my 830 screen is to press and hold the place where I want the data to appear. The box is highlighted and I press it again. This takes me to a menu. I select power. I scroll through the selections until find the 3 second balance. I press it and it appears in the main screen - very easy. I assume the 530 should operate in a similar manner.

The question is does power balance show up in the power menu selections. Good luck
