Wait until both the Sensor Head and Control Unit have been switched on for a minimum of 90 minutes. Perform the following tests:  Verify that the green LED (D10) on the terminal PCB is flashing at equal intervals, indicating that the chest assembly temperature is under control.  Check the final stabilised Sensor Head temperature by measuring the voltage between TB3 terminals 1 and 2 (ground) in the Sensor Head terminal box. This voltage should be 6.6 0.4V.  Select the VIEW option from the main menu. Check that the zirconia sensor temperature is 700 10C.  Check that the combustibles sensor temperature is 300 20C. how to perform this test
