7.1 Operating and maintenance notices
NOTE
The product and electrode must be handled with care and used in accordance with the
technical data. Do not throw or strike.
NOTE
Plugs and sockets must be protected from soiling.
NOTE
If the product is stored at a temperature above 50 °C, or is not used for an extended
period of time, the batteries must be removed. Leaks from the batteries are avoided as
a result.
NOTE
If the product is stored at a temperature above 50 °C, or is not used for an extended
period of time, the batteries must be removed. Leaks from the batteries are avoided as
a result.
NOTE
The electrode should be stored in dry rooms at a temperature between 10 °C and 30
°C. If the storage temperature range is exceeded or undercut, the electrode can be
destroyed. It should always be stored wet in 3 mol/l KCl. Extended storage in distilled
or deionised water will result in depletion of the reference electrolytes.
NOTE
The pH electrode included in the scope of supply should be arranged vertically up-
wards with the connecting cable. A slight angle of inclination does not impair the
measurement.
7.2 Battery
7.2.1 Battery indicator
If the empty frame in the battery display blinks, the batteries are depleted and must be
replaced. However, the device will still operate for a certain length of time.
If the
BAT
display text appears in the main display, the battery voltage is no longer ad-
equate for operation of the product. Now the battery is fully depleted.
