Status: First Stage

CALIBRATE SENSOR S54

The sensor calibration procedure consists of two stages. Each stage is initiated

by pressing SET key. Both stages are required to complete the calibration proce-

dure. For more information see Section 7.1 SENSOR CALIBRATION PROCE-

DURE . The channel number indexes this panel. This panel displays and allows

the setting of the following parameters:

Channel number

Panel index. The Fertigation Controller is equipped with 8 channels for various

sensor inputs. The channels are configured as follows:

1. pH 1 Sensor (4-20 mA analog input)

2. pH 2 Sensor (4-20 mA analog input)

3. EC 1 Probe (4-20 mA analog input)

4. EC 2 Probe (4-20 mA analog input)

5. EC IN Probe (4-20 mA analog input), 3

optional EC probe for

monitoring incoming water supply.

8. Solar Radiation sensor (2 volt analog signal)
