Converting pH or temperature 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.
Resolution: 12000, Current: 4 to 20 mA DC (Load resistance: Max 550 )Output accuracy: Within 0.3% of Transmission output 1 span
1-point Contact output: See ‘Contact output (EVT option)’.
Converting pH or temperature to analog signal every input sampling period, outputs the value incurrent. (Factory default: Transmission output 1: Resistivity, Transmission output 2: Temperature)
If Transmission output 2 high limit and low limit are set to the same value, Transmission output
