Diagnostic menu functions are used primarily during troubleshooting. In this menu, you will
learn to gain individual control of components in the instrument. For example, you can turn
motors on and off, and even "exercise" motor-controlled devices. You can run pumps to check
fluid movement. You can check probe electrical current and even simulate a calibration or
sample cycle. You can check I/O (input/output) devices such as display, keypad and printer for
proper function. And finally, you can check the status of most sensors in the system. These
include the temperature sensor in the Sample Chamber; the level sensors in the reagent and
waste bottles; the Sipper capacitance sensing; and the optical sensors that control motors, the
Sipper Pump and sense the Test Tube Holder position.
Follow the display prompts and information below to learn about the 2700 SELECT menu
diagnostics mode. As before, you will often need to press [0] to return to a previous menu level.
Occasionally, the instrument will print diagnostic information.
