Step 1: Select an Optical Filter
• Check your test method
– Almost all test methods describe the filter type
• If you don’t test to a specific method:
– Outdoor applications: Daylight - Q
– Indoor applications: Window - Q

Step 2: Select Irradiance Settings
• 340 nm Control Point
– For outdoor service environments
• 420 nm Control Point
– For indoor service environments
• TUV Control Point
– 300-400 nm (wideband, general service environments)
– Typically used for European standards

Q-SUN Calibration
• Irradiance sensor
– Every 500 light hours
• Black Panel temp sensor
– Every 6 months
• Chamber air temp sensor
– Every 12 months
• Calibration best practices
– Calibrate whenever test conditions are changed
– Calibrate at operating conditions
– Always calibrate the lamps before calibrating the Black Panel
