(R1, R2, R3 and R4, RF are for common use, respectively.) |
| Contact input | No. of inputs: 1 Contact status: Open collector no-voltage contact a Contact function: Transmission output hold |
| Communications output | RS-485 input/output |
| Calibration function | Conductivity: Based on the specified compensation coefficient for the cell constant (parameter input) Temperature: Calibrated by comparing with the reference thermometer |
| Transmission output Hold function | Selectable from the previous value hold and optional value hold (However, only the previous value hold is available during the maintenance mode. |
