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
