The Wöhler A 550 is equipped with a rechargeable lithium ion battery 3.7 V. Only after a
long working period the battery has to be changed. In this case send the analyzer to your
dealer or change the battery as follows:
•
Switch off the analyzer. Open the analyzer as
described before in the chapter "sensor re-
placement".

tery.
