9.2.2. cleaning and recalibration at the
factory
If the sensor is excessively soiled or damaged by the operating gas,
the device may deviate significantly in terms of the mass flow-rate
measurement. Cleaning or replacement followed by recalibration at
the factory will then be required.
note
• Recalibration must be carried out at the factory as it requires
the use of very precise references and a specific digital
communication system.
