• Measuring method Integration
• Measurement resolution 15 bits + sign
• Interference frequency suppression None | 10 Hz | 50 Hz | 60 Hz | 400 Hz
• Refresh rate / conversion rate Number of active channels x conversion time +16 ms for wire break detection for each channel when activated. The conversion time will depend on the interference frequency suppression:
  • None: 8 ms
  • 400 Hz: 45 ms
  • 60 Hz: 109 ms
  • 50 Hz: 128 ms
  • 10 Hz: 342 ms
• Diagnoses Upper measuring range limit exceeded (overflow), lower measuring range limit fallen below (underflow), wire break, parameter assignment error
• Process alarms Upper and lower limit per channel
