Thanks for that. I actually noticed that as I was reading through 
the user manual for inspiration, I then found an example with a 6 
times right shift and an arithmetical and worked on to the output of 
the ADC. I always thought that was to extract the information for 
that particular users' program!

Stll adding that in and a few other slight modifications and my 
project is working fine.

Thanks,
