Measuring method Integration
Interference frequency suppression None / 10 Hz / 50 Hz / 60 Hz / 400 Hz
Refresh rate / conversion rate
Number of active channels x conversion time
The conversion time will depend on the interference
frequency suppression setting being used:
None: 8 ms
400 Hz: 45 ms
60 Hz: 109 ms
50 Hz: 128 ms
10 Hz: 342 ms
Diagnoses
Upper measuring limit exceeded (overflow)
Lower measuring limit fallen below (underflow)
Parameter assignment error
Process alarms Upper and lower limit per channel
Error limits
Operational error limit ±0.5% within the entire temperature range,
relative to the nominal range
Basic error limit ±0.3%, operational error limit at 25 °C, relative to
the nominal range
