Accuracy at room temperature
Accuracy class
Standard
Option
1) Including non-linearity, hysteresis, zero-point and full scale deviations (corresponds to measured error per IEC 61298-2). Calibrated in
vertical mounting position with process connection facing downwards.
Temperature error
In the range of -20 ... +80 °C [-4 ... +176 °F] the instrument is actively compensated.
-20 ... +10 °C [-4 ... +50 °F]: ≤ ±0,2 % of span/10 K
10 ... 60 °C [50 ... 140 °F]:
60 ... 80 °C [140 ... 176 °F]: ≤ ±0,2 % of span/10 K
1) For the optional accuracy at reference conditions of ≤ ±0.05 % of span there is an additional temperature error of ≤ ±0.05 % of span.
Long-term stability
≤ ±0.1 % of span/year
Total error band (10 ... 60 °C) [50 ... 140 °F]
≤ ±0.1 % of span
