Hi
PLEASE, I LOOK FOR THE DOCUMENTATION FOR:
a) CALIBRATION PROCEDURE of THE TUBE TESTER "PRECISION 912 "
b) Tension control procedure at the respective pins of the sockets, to check that the transformer is ok
c) Features of the "LINE ADJ" potentiometer, and where it is possible to find
I thank you all
Francis

Lots of info on the Precision Testers is available on Chris' site here:
http://oldradios.50webs.com/precision/

It may or may not answer your questions.

You should also google "precision tube tester calibration" which will return a number of hits, especially from this forum.

I found you operating instructions and a schematic. Yes, it says "910", but it includes the 912 model:

Here's another manual that contains 912 operating instructions, along with an updated supplementary tube chart at the end.
