After I have put new oil in my pump ; it was tested again; it has been partially repainted ; added intake and exhaust? components; decided to give links of my Web showing photos of my new toy and TC gauge measurements. I don't plan to do anything more on it; plan to using it for testing my largest diffusion pump.
The TC gauge reading is shown: http://vaughns_page.50webs.com/vacuum/1402Ebay_2/100_1684b.JPG
When I initially got this gauge from Ebay and tested it with one of my diffusion pumps; the needle pegged well below ? zero very quickly after warming up. After running for some time the controller? was adjusted so that the needle was set to zero. Although the 1402 seems to pump fairly quickly at first; it takes quite a long time for it to reach the value indicated. I am not claiming that the TC
value is absolutely correct ; just what it reads after being zeroed with a diffusion pump.
