b) Batteries
• Correct polarity must be observed while inserting the battery.
• The batteries should be removed from the device if it is not used for a long period
of time to avoid damage through leaking. Leaking or damaged batteries might
cause acid burns when in contact with skin, therefore use suitable protective
gloves to handle corrupted batteries.
• Batteries must be kept out of reach of children. Do not leave batteries lying
around, as there is risk, that children or pets swallow them.
• All batteries should be replaced at the same time. Mixing old and new batteries in
the device can lead to battery leakage and device damage.
• Batteries must not be dismantled, short-circuited or thrown into fire. Never
recharge nonrechargeable batteries. There is a risk of explosion!
c) Cell Chamber
• The cell chamber (4) must be kept dry. Do not insert wet cells (7) for testing! Water
can destroy the electronic components.
d) DPD Method Performance
• The accuracy of the measurements depend on factors relating to the overall
method which include the meter, the glass cells, reagents and testing procedure.
e) Sample Cells
• These are made from glass and can get damaged if dropped. Handle with care.
• Discard cells (7) that are badly scratched, this can affect the accuracy of results.
Use the included cell covers (5) and caps (6) for protection during transport and
storage.
