Electrical conductivity
Max. measured error not specified.
Accuracy of outputs
o.r. = of reading; o.f.s. = of full scale value
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).
Current output
Accuracy Max. ±0.05 % o.f.s. or ±5 µA
Pulse/frequency output
Accuracy Max. ±50 ppm o.r.
