Cleaning the
sensor module
We recommend to clean the sensor module thoroughly, especially before
measuring low conductivity values. Before measuring, thoroughly rinse the
sensor with deionized water.
5.4 Transport
Activate the cleaning mode. Thus, the instrument will not interpret any
contact with the touch screen as an entry while being transported, e. g. in a
pocket (see chapter 5.3).
5.5 Disposal
Dispose of the meter without the battery and the sensor module as electronic
waste at an appropriate collection point.
