If you get an 'E9 Wrong Tray Error' on your Idexx Measuring Instruments, it suggests the test strip tray needs cleaning, is damaged, or an LED on the phototransistor is defective. Start by turning off the analyzer and removing the test strip tray. Then, carefully clean and dry the tray. If the error continues, contact IDEXX Technical Support for a replacement.
