Technical specifications
Interference frequency suppression, error limits
Interference frequency suppression at f = n x (f1 ± 1%), (f1 = interference frequency) n = 1.2, etc.
• Common mode interference (CMV < 250 VAC)
• Series-mode interference (peak interference value <
rated input range)
> 130 dB
(3)
> 90 dB
Crosstalk between inputs > 130 dB
(3)
Operational limit (across entire temperature range, relative to measurement range end value in the selected input range, 0-
60 °C).
Note: This limit does not cover the temperature-error comparison points.
