Converting Turbidity/SS input value or MV to analog signal every input sampling period, and outputs theTransmission
value in current. If Transmission output high limit and low limit are set to the same value, Transmission
outputoutput will be fixed at 4 mA DC. Bar graph indication is possible in accordance with transmission output.
