5.6 The White LED
A white LED is used to illuminate the measurement cuvette for easy viewing of the
instrument operations. During the Zeroing portion of the cycle and the Measurement
portion of the cycle, when the green LED is active, the white LED is turned off to lower
interference. This normal operation for the instrument and does not represent an error or

dependant on the severity of the problem, but is still turned off as described above. Please
note that any fault is always posted to message queue on the lower portion of the LCD.
