VALUE
VALUE
If a measuring sensor (other than a chlorine measuring sensor) is connected to an AI1 or AI2 analogue intput, the
analogue input can be calibrated:
• either with respect to the measured value, at two points or at one point. See section 8.11.6 Calibrating an
analogue input, AI1 or AI2, at two points, with respect to a measured value other than chlorine or section 8.11.7
Calibrating an analogue input, AI1 or AI2, at one point (offset), with respect to a measured value other than
chlorine.
• or with respect to the current or voltage received on the input. See section 8.11.8 Calibrating an analogue input
connected to a current output or a voltage output.

To read the date of the last calibration of an analogue input, see section 8.11.11.
→
To enter the periodicity of calibrations, see section 8.11.12.
→
To read the date of the last maintenance operation carried out on the sensor connected to the analogue input,
see section 8.11.13.
→
To enter the periodicity of a maintenance operation to be carried out on the sensor connected to the analogue
input, see section 8.11.14.
→
To return to the calibration parameters for the analogue input, as carried out in the factory, see
section 8.11.15.
