| Sampling rate / Display rate | The input is read @40mS / the display is updated @1 second. |
| Indicating Accuracy | +/- 1 °C for Thermocouple throughout the range and +/- 0.1 °C for Pt-100 for (4-20)mA or (0-10)V - absolute to the linear input signal. |
| Display | 4 digit 0.5" Red 7-segment display for process variable. |
| 4 digit 0.5" Green 7-segment display for set value and PID parameters | |
| Settings | Using Front panel feather touch key board to set various parameters like Set values, Hysterisis values, Span hi/lo values, MODBUS slave ID, Input selection, calibration etc |
