1 % + 0.5 % + 0.5 % = 2 %. The overall accuracy refers to the overall measuring range of 0 ... 25 mA Overall accuracy in mA in relation to the overall measuring range: 25 mA * 2 % = 0.5 mA Operating Manual PNOZ m EF 4AI | 13 1004650-EN-02... - Page 14 Sensor's measuring range: 0 ... 500 mbar at 4 ... 20 mA. Resolution of the sensor: 500 mbar / (20 – 4 mA) = 31.25 mbar per mA. The overall accuracy in mbar is therefore: 1 mA * 31.25 mbar per mA = 31.25 mbar.

You can define switching thresholds, which can be used to monitor certain process vari- ables (e.g. temperature values). You can monitor whether a numerical value is greater or less than a configured switching threshold. Operating Manual PNOZ m EF 4AI | 20 1004650-EN-02... -
Page 21: Range Monitoring
2 threshold values are configured per switching threshold. One threshold value (switch-on threshold) defines when the affected output is switched on. The second threshold value (switch-off threshold) defines when the output will be switched off again. Operating Manual PNOZ m EF 4AI | 21 1004650-EN-02... -
