Accuracy of outputs
The output accuracy must be factored into the measured error if analog outputs are
used, but can be ignored for fieldbus outputs (e.g. Modbus RS485, EtherNet/IP).
The outputs have the following base accuracy specifications.
Current output
Accuracy Max. ±5 µA
Pulse/frequency output
o.r. = of reading
Accuracy Max. ±50 ppm o.r. (over the entire ambient temperature range)
o.r. = of reading; 1 g/cm 3
