Maintenance and Cleaning

Contaminations and deposits on the electrode affect the result of
measurement. Therefore it is important to keep the electrode always
clean. Use only distilled or de-ionised water for cleaning (rinsing) the
pH-electrode and paper napkins for dabbing. Do not use detergents
that contain carbon, petrol, alcohol or similar substances for clean-
ing purposes. This will corrode the surface. Moreover the vapours
are detrimental to health and explosive. Sharp-edged tools, screw-
driver or metal brushes are a taboo for cleaning.
Always store the pH electrode in the provided storage solution.
While doing so first put on the end cap on the electrode. Now put on
the o-ring on the electrode and screw the end cap to the tin.
Replacing the battery
If the battery symbol „ " is displayed on the display, the batteries
– +
must be replaced as soon as possible to prevent erroneous mea-
surements.
To replace the batteries, proceed as follows:
- Switch off the device.
- Loosen the two battery compartment screws on the back of the
device, and slide the lid of the battery compartment (5) out of the
housing.
- Replace the run-down battery with a new one of the same type
(e.g. 1604A).
- Close the measuring device again carefully in reverse sequence.
Do not leave run-down batteries in the measuring device.
Even leak-proof batteries can corrode and thus release
chemicals which can be detrimental to your health or
damage the appliance.

To prevent leakage, remove the batteries if the device is not used
for longer periods of time.
Leaking or damaged batteries may cause burns if in contact with
skin. It is therefore advisable to use suitable protective gloves.
Make sure that the batteries are not short-circuited. Do not throw
batteries into fire.
Batteries should not be recharged. Danger of explosion.
