5) Including non-linearity, hysteresis, zero point and full scale error (corresponds to
error of measurement per IEC 61298-2).
Adjusted in vertical mounting position with lower pressure connection.
6) In individual cases equipment exposed to strong electromagnetic fields with
frequencies up to 2.7 GHz may show increased measurement errors of up to 3 %.
To avoid such influences on the measurement signal do not operate the equipment
in proximity to strong transmitters or radio installations, or use suitable sheath
current filters.
