I pressurized my ES-P for the first time today.    Some questions:

1.        Is the pressure head supposed to be illuminated?  There was a dimming wire shown in the wiring diagram.  I hooked it up but am not getting any illumination.

2.       At 17,500 feet, I had a cabin altitude of 3,400 feet and an indicated pressure differential of 5.8 psi.  I thought the maximum was supposed to be 5.1 psi.  Why the difference?  The Dukes components don’t appear to be adjustable.

Thanks for the help!
