*)
in an industrial environment
* With measurement per EN 61326, May 2004 edition, Annex F, burst to shielding of the transducer or bus line, the class accuracy of 0.1 is
complied with when using filter frequencies up to 2 Hz. When a filter frequency of 100 Hz is used, the measurement variation can be as much
as 1.3%.
