≤ ±0.5 % of span (option)
≤ ±0.3 % of span (option, not possible in combination with DIP switch)
Including non-linearity, hysteresis, zero offset and end value deviation (corresponds to measured
error per IEC 61298-2). Calibrated in vertical mounting position, process connection facing
downwards.
The existence of strong electromagnetic fields in a frequency range of < 2.7 GHz can result in
increased measuring errors up to 1 % of span. Do not install the instruments in the vicinity of
strong electromagnetic sources of interference (e.g. transmitting devices, radio equipment), or
use sheath current filters where applicable.
