Tips for an accurate measurement
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.
• Remove the battery from its location and replace it with a new one, inserting the
negative end first.
• Insert the battery cover and replace the screw with a screwdriver.
• 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 lower 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.
