Calibrate the Flow Meter
Calibrate the flow meter using one of the following methods:
1.Flow Calibration for Normal Valves, see Section 17.8.1.
2.Flow Calibration for Balanced (Hardi) type valves, see Section 17.8.2.
3.Manual entry of Calibration Factor, see Section 9.0 (OPTIONS/Sensors/Flow)
17.8.1Flow Calibration for Normal Valves
1.Disconnect a line from one valve going to a boom section. Connect a line from the valve to the measuring container. (20 litre drum)
2.Select the "Speed Readout" and set a test with the arrows close to normal spraying speed.
3.Select the boom section that has been disconnected from the valve and is now supplying the measuring container. The section should turn green on the screen.
4.Select the tank icon on the screen you are calibrating,
5.Select "Cal X", (X is the tank number) A window with "CALIBRATE TANK X" appears on the right of the screen.
6.Start the pump and select "Flow On/Off"
7.The Valve and the Master will turn on, and liquid will flow into the measuring container. The pulse readout next to the flow button should increment.
8Press the "Flow On/Off" button when there is approximately 20 litres in the measuring container. Measure this volume as accurately as possible and enter this volume into appropriate section of the window.
9The ZYNX will calculate the correct FLOW CAL. FACTOR and register this into the system.
10Press the ‘Reset’ button and repeat the procedure if required.
11Select done when finished
