Marconi 2382

[keynaboutradios]

Hi everyone!
I am new to electronics so be kind to me!!!!!
Just bought my first ever Spectrum analyzer Marconi 2382/2380 really pleased with it, but trying to find a complete user manual so I can solve my problem, I have bought a attenuator for it, and trying to find out if it is possible to offset the attenuator value so I can read correct value on screen without having to deduct 30db from on screen value, hope that makes sense?
Thanks
Justin

Thanks xrunner
I'm affraid not!, I have read that one, and it refers to chapter 3 for more detailed explanation on using, that one is chapter 1.
Thanks for replying tho.
