Deviation determined according to the limit point method according to IEC 60770
Specifications refer to the set span. Turn down (TD) is the ratio: nominal measuring range/set span.
Deviation with turn down 1 : 1 bis 5 : 1
Influence of the medium or ambient temperature
Specifications refer to the set span. Turn down (TD) = nominal measuring range/set span.
Average temperature coefficient of the zero signal
In the compensated temperature range of 0 ... +80 °C (+32 ... +176 °F), reference temperature
20 °C (68 °F).
Average temperature coefficient of the zero signal upon execution < 0.2 %
Ʋ Turn down 1 : 1
Ʋ Turn down up to 5 : 1
Average temperature coefficient of the zero signal upon execution < 0.1 %
Ʋ Turn down 1 : 1
Ʋ Turn down up to 5 : 1
