CALIBRATE SENSORS – S67
Channel: 01
Now: 02.3 Ref: 02.5
Status: First stage
CALIBRATE SENSOR S67
The sensor calibration procedure consists of two stages. Each stage is initiated
by pressing SET
SET SET SET SET key. See section SENSOR CALIBRATION PROCEDURE for
more information. Both stages are required to complete the 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 Sensor (4-20 mA analog input)
2. EC Sensor (4-20 mA analog input)
3. EC Sensor for input water (4-20 mA analog input)
4. Temperature sensor (4-20 mA analog input)
7. Differential pressure 1 (0-30V analog input)
8. Differential pressure 2 (0-30V analog input)
− Now - Real time sensor value for the indexed channel
− Ref - The calibration reference value (entered by user) for the indicated stage
of calibration for the indexed channel.
− Status indication - Current state of the calibration procedure (current stage/
result).
CONTROLLER ID – S68
Comm ID:00
User ID:1234
CONTROLLER ID S68
The panel allows the setting of the controller identification numbers necessary
when several Fertigation Controllers work together in a network. This panel
displays and allows the setting of the following parameters:
− Comm ID – identification number of the controller in a network.
− User ID – Identification number of the controller.
