NOTICES:
The calibration can be cancelled at any time by placing the magnetic wand onto the
marking » S « when calibrating the zero point or on » 0 « during a span calibration.
The individually selected span gas concentration may deviate from the span gas
concentration set at the factory. This must be taken into consideration during span
calibration and must be subsequently entered on the calibration label of the
device.
How to Dispose of the Instrument
From August 2005, regulations apply to the whole of the EU for the disposal of electri-
cal and electronic devices; these regulations are set in the EU Directive 2002/96/EG
and in national laws relating to this device.
