CAUTION!
Before cleaning the instrument, disconnect the electrical

Clean the instrument with a moist cloth. This applies in

particular to thermometers with a case made of plastic
and cable sensors with plastic-insulated connecting
cable, to ensure that any risk of electrostatic discharge is
avoided.
Electrical connections must not come into contact with
■
moisture.
Wash or clean the dismounted instrument before returning
■
it, in order to protect persons and the environment from
exposure to residual media.
Residual media in dismounted instruments can result in
