Default TV7d/U military tester....how to calibrate

Hello,
I received a Tv7d/U military tube tester from a friend's estate (husband passed, wife thought I might like to have it). I have read the manual through and though and have learned how to test tubes with it. I think it is not calibrated well though. I am finding tubes that are new and/or recently tested at over 100% by other testers only test at sometimes 30 to 60% of expected. In fact off all the tubes I have tried to test with it I have found they all test well below where I would expect them to test.

I have searched around a little on the web about calibrating these but have come up empty handed. Can anybody give me some advice about this or tell me how to do it? I would even consider paying someone to calibrate it for me.
Thanks for your help,
Jeff
