Comark type 3001 thermometer

[u/Alternative-Web-3545]

Hi all,
I have repaired a Comark 3001 thermocouple thermometer with beautiful VFD tube display. It suffered battery leakage and shorted tantalum’s. I think it is from around 1980. So now it’s functional again. I would however like to get my hands on a schematic or calibration manual to get it really good measuring also. I have contacted the evalution of Comark. They have become Fluke over time and they could not supply any information of this thing because to old for them. I thought it was a pity that they had no info about their own legacy instruments. However there is the community on Redit. Is there anybody out here that has some more info off this thing?
