This technical work package details the yearly inspection and calibration procedures for the Continuous Emission Monitoring System (CEMS) at the Ankerlig Power Station. It specifies the tools, safety precautions, and step-by-step actions required to maintain NO, CO, and SO2 analysers, including a 2% deviation threshold for triggering recalibration and a 6 mV replacement threshold for oxygen sensors.

• The inspection and calibration of emission monitoring equipment at Ankerlig Power Station is a yearly requirement that typically takes approximately 3 hours to complete and requires one competent person.
• General equipment checks for the monitoring system include testing indication panel lamps, cleaning the compartment with a vacuum cleaner, verifying the operation of the heater and air conditioner, and inspecting filters for fouling (indicated by brown or yellow discoloration).
• The calibration process for NO, CO, and SO2 analysers involves using test gas cylinders with a pressure above 5 bar, maintaining a flow of 60–80 l/h at approximately 0.2 bar, and purging the system for at least 5 minutes. If the analyser display deviates by more than 2% from the test certificate values, the analyser must be recalibrated.
• Specific maintenance thresholds are set for the oxygen sensor, which must be replaced if its voltage drops below 6 mV.
