Please check the preparation of the zero cuvette.

Inverted Cuvettes: The sample and the zero cuvette are inverted.

Under Range: A blinking “0.00” indicates that the sample absorbs

less light than the zero reference. Check the procedure and make sure
you use the same cuvette for reference (zero) and measurement.
Over Range: A flashing value of the maximum concentration indicates
the reading is over range. Dilute the sample and re-run the test.
