On Zero Reading: Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette. Dead battery: This indicates that the battery is dead and must be replaced. Once this indication is displayed, normal operation of the instrument will be interrupted. Change the battery and restart the meter. Light Low: There is not enough light to perform a measurement. Please check the preparation of the zero cuvette. No Light: The instrument cannot adjust the light level. Please check that the sample does not contain any debris. On Sample Reading: Inverted cuvettes: The sample and the zero cuvette are inverted. Zero: A zero reading was not taken. Follow the instructions of the measurement procedure for zeroing the meter. 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 an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and re-run the test. During Calibration Procedure: Standard Low: The standard reading is less than expected. Standard High: The standard reading is higher than expected. Other Errors And Warnings: Cap error: Appears when external light enters in the analysis cell. Assure that the cuvette cap is present. Cooling lamp: The instrument waits for the lamp to cool down.
