use of the devices results in a loss of the warranty claims�
• Correct operation and compliance with the measurement accuracy can only
be ensured if the environmental conditions specified in the technical data are
adhered to� Ensure that the maximum pressure range, measuring range and
permitted ambient temperature are not exceeded�
3 Functions and features
