The gray meter in the back is the supply voltage. The meters in the front shows the output of the 7809 regulator and the output of the 7909 regulator (the 7909 is the negative value). Now I probably should throw some caps at the circuit but this shows it works.
I suggest you haven't connected the black leads of both front meters to your GND. Until you do that and get +/-9V I am sceptical to the max.
