Well done on that find. I love Takeda Riken (later, "Advantest") equipment. The quality of their gear seems much, much better than Leader (another hugely popular Japanese manufacturer). I have a few nixie TR multimeters on my bench and they work wonderfully. The later nixie models tend to show up quite often.
Unfortunately, Japanese manufacturers very rarely made documentation available (even in the earlier days). I did find a mention of your TR6155 in a special article commemorating 60 years since TR/Advantest was formed, in the Semiconductor Equipment Association of Japan's "SEAJ Journal" vol.142 here: http://seaj.or.jp/journal/pdf/no142.pdf . The mention is in the 2nd-last paragraph of section 1, where it indicates that the TR6155(/6255) was the first all-transistor multimeter that TR made. They use what might be translated as "epoch-making" for emphasis. It might be quite rare! Enjoy using it and having it on your bench!
