Floating Average and Reference not working

[horstdroege]

Good morning,

I am using
TP MR3040
Canon EOS 5DIII with external intervalometer
qdslr 3.5.1 on iPAD mini

In qdslr, LRTimelapse I can change manually the settings of the camera so connection iPAD - camera works. In the Auto Holy Grail the Floating Average and Reference stays always on "0". This is also the case by using the internal intervalometer of qdslr.

Anyone has an idea what I may do wrong here ?

Cheers Horst
