Mr Kitchers book is very good and he also does some demo video's on YouTube. However the testing is very easy after doing a couple of jobs, the hard part is knowing what all the results mean, how to spot faults and how to use the tester to help remedy the faults. I don't think any book or video will help with that. A C&G 2391/2 course is possibly your best bet.
Good Luck
