K-FACTOR
If the main pipe has been fitted with a flow sensor, you will need to set the 'K-
factor' (pulse/litre). Follow the instructions provided with the sensor to install
the sensor correctly and to determine the K-factor.
To set the K-factor, navigate this path:

Irrigation control
You also need to set up the following in the software:
Assigning valves to valve groups
Valves simultaneously
Periods
Volume and duration
Dosing fertilizers and acid
Pre- and post-flushing
Start requirements
More information about using and setting up the irrigation program can be found in
the section "Assigning valves to valve groups" on page 45.

Calibrating the sensors
The sensors need to be checked regularly in order to ensure accurate measurements.
This must be done at least once per year. If the measurements taken by the
verification sensor deviate from those of the control sensor, you need to calibrate the
sensors.
The calibration process requires special calibration solutions. To calibrate an EC
sensor, you will need EC 1.4 and EC 5.0 solutions. To calibrate a pH sensor, you will
need pH 7.0 and 4.0 solutions. The order in which the solutions need to be used is
fixed and may not be reversed.

Calibration steps
The calibration process involves a few simple steps; the controller will describe the
steps that you need to carry out.
Make sure that you have a bucket of clean tap water to hand.
