Note 1: After long-term storage a zero calibration is recommended.

Note 2: All corrosive environments are excluded.

Note 3: Accuracy is defined after zero calibration or after minimum 23 days of continuous operation. The tolerance of the

span gas (2% unless otherwise requested) and test gas adds to the total uncertainty.

Note 4: For reference see TN-025 "on pressure sensitivity".

Note 5: The specifications are valid for the output load connected to Ground G0.
