Lithium-ion batteries are 'memory-free' and prefer a partial rather than a full discharge. Constant partial
discharges with frequent recharges will not cause any harm. Frequent full discharges should be avoided
whenever possible. Ideally the sensor should be stored at about 40% or more charge.
The speed at which a lithium-ion battery will age is governed by both its storage temperature
(preferably less than 40˚C) and state-of-charge. Eventually the battery will no longer deliver the
stored energy and will need to be replaced. A fully charged battery that loses its charge quickly will
demonstrate the need for replacement. When this happens, contact Data Harvest.
Updating the Firmware
Occasionally Data Harvest may release updated firmware which will contain improvements or new
features. Updates will be made available from the product specific page on the

General cleaning
procedure: - Soak the electrode in 0.1 mol dm
10 to 30 minutes. Rinse thoroughly with distilled water. Soak in its storage solution for at least 2
hours before use.
The pores of the reference junction may become clogged, if so heat to 50˚C in 3 to 4 mol dm
Potassium Chloride (KCl) or pH 4 buffer solution for 1 hour, then allow to cool to room temperature
in the same solution. Rinse with distilled water and soak in its storage solution for at least 30 minutes
before use.
