Tips for an accurate measurement

• It is important that the sample does not contain any debris.
• Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil and dirt. Wipe it thoroughly with HI 731318 or a lint-free cloth prior to insertion.
• Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove bubbles by swirling or by gently tapping the cuvette.
• Do not let the reacted sample stand for too long after reagent is added, as accuracy will be affected.
• After the reading it is important to immediately discard the sample, otherwise the glass might become permanently stained.

Tips for an Accurate Measurement

• Ensure the sample does not contain any debris.
• Whenever the cuvette is placed into the checker, it must be dry outside and free of fingerprints, oil and dirt.
• Wipe the cuvette thoroughly with HI731318 microfiber cleaning cloth or a lint-free cloth prior to insertion.
• Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.
• Do not let the reacted sample stand too long after reagent has been added, as accuracy will be affected.
• Discard the sample immediately after the reading has been taken or the glass might become permanently stained.

Light High: There is too much light to perform a measurement. 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 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. Battery Low: The battery must be replaced soon. 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.
