CG1000-RTP OXYGEN ANALYZER Follow these safety precautions when working on the sensor: Disconnect AC power from the analyzer before performing any main- tenance or troubleshooting. The furnace and furnace insulation cover are hot during normal oper- ation (up to 500°F/260°C inside the furnace insulation cover). Allow analyzer components to cool for at least an hour before working inside the analyzer. -
