Converting resistivity, temperature or MV to analog signal every input sampling period,
outputs the value in current. (Factory default: Resistivity)
If Transmission output 1 high limit and low limit are set to the same value, Transmission
output 1 will be fixed at 4 mA DC.
Transmission output can be indicated with the bar graph.
