4.2.2. điều chỉnh hệ thống thermostation cánh quạtThis screen makes it possible to adjust the thermostation system of the rotor in such a way that the reactions temperature is 37ºC. To make this adjustment, place a well rotor in position and ensure that the analyzer has been initialised. The rotor can be automatically filled with distilled water by pressing the corresponding button. Once filled, the technician must wait a few minutes for the rotor to be thermostated. The temperature in the rotor wells must be measured with a temperature calibrated at 37ºC through the dispensing hole of the rotor cover. A button makes it possible to turn the rotor in increases of 15 wells to change the well on which the measurement is being taken. The program shows the control set point temperature, which is the parameter that must be adjusted for the temperature of the rotor to be correct. This parameter must be other than 37ºC. The technician must measure the temperature of the water with the calibrated thermometer in the wells and enter the temperature on the screen. The analyzer automatically modifies the set point temperature in accord with the temperature measured with the thermometer for the rotor reactions temperature to be 37ºC. The technician can modify this set point temperature proposed by the program. On pressing Adjust, the analyzer thermostates the rotor with the new set point. Each time the set point temperature is modified, wait 5 minutes before performing new dispensing operations for the rotor temperature to become stabilised. The technician must repeat this process until the rotor temperature is as near as possible to 37ºC. Pressing the Store button, the analyzer stores the current value of the adjusted set point temperature. Pressing the Cancel button keeps the last stored value and the current value is not stored. Pressing the Restore button restores the initial screen input value.
