Errors and warnings:
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” 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. Change the battery and restart the

•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.
To save the battery, the instrument shuts down after 10 minutes of non-use.
One fresh battery lasts for a minimum of 5000 measurements. When the battery is dead
the instrument will display “bAd” then ”bAt” for 1 second and then turns off.
To restart the instrument, the battery must be replaced with a new one.
To replace the instrument’s battery:
•Turn the instrument off by holding the button until the meter shuts off.
•Turn the instrument upside down and remove the battery cover with a screwdriver.
