Suppression of interference, limits of error
Interference voltage suppression for f = n x
(f1 ± 1 %),
(f1 = interference frequency)
• Common mode interference
(peak value of interference < rated value
of input range)
min. 70 dB
Crosstalk between the inputs min. - 50 dB
Operational limit (in the entire temperature
range, with reference to the input range)
± 0.6%
Basic error limit (operational limit at 25° C
with reference to input range)
± 0.4%
Temperature error (with reference to the
input range)
± 0.005 %/K
Linearity error (with reference to the input
range)
