To conserve 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
replace the 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. Remove the battery
from its location and replace it with a new one, inserting the
negative end first. Replace the battery cover and screw.
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
HI731318
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.
