Maintenance and care

The analyzer

required only little maintenance:

Charge the battery completely in case you will not use the analyzer over
a longer period. Then recharge the battery every 6 months (using the
included battery charger connected to the USB port).

NOTE

Please note that correct operation of the analyzer is
only ensured if the sensors are adjusted regularly.

►

Depending on the intensity of use, the sensors have

to be adjusted / calibrated 1-2 times a year.
