Measured value resolution Dead band as per EN61298-2:
• Digital: 1 mm (0.04 in)
• Analog: 4 µA
Response time The response time can be configured. The following step response times apply (in
accordance with DIN EN 61298-2) when damping is switched off:
Tank height
<10 m (32.8 ft)
Sampling rate
1 s -1
Response time
<3 s
In accordance with DIN EN 61298-2, the step response time is the time following an
abrupt change in the input signal up until the changed output signal has adopted 90%
of the steady-state value for the first time.
Influence of ambient
temperature
The measurements are carried out in accordance with EN 61298-3

Standard version: average T
C
= ±3 mm (±0.12 in)/10 K
• Analog (current output):
• Zero point (4 mA): average T
K
= 0.02 %/10 K
• Span (20 mA): average T
K
= 0.05 %/10 K
