I have one Surgical CO2 laser of 50W manufactured by Heraeus Surgical Inc (USA), labeled as Laser Sonics, model Paragon 50 with problem in thermopile calibration. In the initial self-test, all are OK, but when in continuos mode use, few seconds later, the display shows the message POWER HIGH. I made some adjusts in the thermopile board trimpots. I made the machine to operate well until 10W, but when I adjust for more then it, the error message is showed again. Someone have one tip to resolve this problem or have the schematic of this machine?

Thanks in advance,
