The checker shows clear warning messages when erroneous conditions appear and when measured values are outside the expected range. The information below provides an explanation of the errors and warnings, and the recommended action to be taken.
Light High: There is an excess amount of ambient light reaching the detector. Please check the preparation of the zero cuvette.
Light Low: There is not enough light to perform a measurement. Please check the preparation of the zero cuvette.
Inverted Cuvettes: The sample and the zero cuvettes are inverted. Swap the cuvettes and repeat the measurement.
Under Range: A blinking "0.00" indicates that the sample absorbs less light than the zero reference. Check the measurement procedure and make sure to use the same cuvette for reference (zero) and measurement.
Over Range: Maximum concentration value displayed blinking indicates the measured value is outside the limits of the method. Verify that the sample does not contain any debris. Dilute the sample and repeat the measurement.
Battery Low: Battery level is too low for the checker to function properly. Replace the battery with a new one.
Drained Battery: The battery is drained and must be replaced. Replace the battery with a new one and restart the checker.
To save the battery, the checker shuts down after 2 minutes of non-use.
A fresh battery lasts for a minimum of 5000 measurements. When the battery is drained, the instrument displays "bAd" then "bAt", and turns off.
