3.Specications

3.2 Accuracy data

Accuracy at reference conditions

Including non-linearity, hysteresis, zero oset and end value deviation (corresponds to

measured error per IEC 61298-2).

Accuracy

Standard 0.15 % of span

Option 1 0.10 % of span

Option 2 0.20 % of span

Mounting correction

-20 ... +20 %

Non-repeatability

≤ 0.15 % of span

Behaviourwithturndown(withaccuracy0.15%)

Turndown = basic measuring range : scaled measuring range

■

1:1 ... 5:1 No change in accuracy

■

> 5:1 < 0.03 % x turndown

Long-term stability

≤ (0.1 % x turndown)/year

Thermalchangezeropoint/span(referencetemperature20°C)

In compensated range 10 ... 70 °C:

< 0.05 % / 10 K x turndown

Outside compensated range:

Typical < 0.1 % / 10 K x turndown

Thermalchangeofthecurrentoutput(referencetemperature20°C)

< 0.05 % / 10 K, max. 0.15 %
