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.
Battery Replacement
To save the battery, the checker shuts down after 7 minutes of non-use and
2 minutes after reading.
A fresh battery lasts for a minimum of 5000 measurements. When the battery is
drained, the instrument displays “bAd” then ”bAt”, and turns off.
To replace the battery, follow the next steps:
1.
Press and hold the ON/OFF button to turn the checker off.
2.
Turn the instrument upside down and use a screwdriver to unfasten the screw and
remove the battery cover.
3. Remove the old battery, replace it with a new 1.5V AAA battery, inserting the
negative end first.
4.
Replace the battery cover, fasten and tighten the screw.
