Hi,

I've bought an Audio Precision Portable One Plus [1995 year, labelled 1995 calibration, sn 21260].
I'm using it a lot, its a fantastic machine.

About calibration:
my unit has the GPIB option, and I was told by customer support [great indeed!] that, having it, its still possible to have it calibrated at the factory, in Netherlands.
But I am also curious about the possibility to do the calibration myself, not only for money, its a DIY issue :)

Only worse thing, the service manual needed for calibration costs a lot [200$].
I've still not bought it, because I dont know if I have [will have] all the gear needed for calibration.
If not, it would be a waste.

So, I'm asking here, do someone has taken this route and knows what are the needed tools?

Thanks!
