Hi guys..

I have one Waters Xevo TQMS. Suddenly, the Detector got disconnected from the PC. I started it over and over again with no success.. After that, I reset it stinging with some Peek tubing on the front hole with no success. After that, I reset the Electronics with the switches on the back of the detector with the same results. In addition, Before the instrment got wrong, there was about 5 minutes since I push the detector on and a few beep sound on. Then I was able to connect it to the PC. When the problem got present, it makes four beeps and then nothing happens. Is there anybody who pass thru the same? Since now.. Thanks for your help!!
