⊙ irrigation volume check

⊙ EC / PH measurement of soil and culture ground

2. Weekly

⊙ Cleaning all filters

⊙ Fertilizer volume check of fertilizer tank

⊙ Ventury check and cleaning

⊙ EC / PH sensor cleaning

3. Monthly

⊙ Drip tape check and cleaning

⊙ Check whether all valves operate normally

⊙ Normal operation check of other equipment and facility

4. After cultivation

⊙ Culture ground and soil sterilization

⊙ Culture ground cleaning by water

⊙ Fertilizer supply piping cleaning


EC Converter ZERO (standard value) adjustment method

ZERO Adjustment of EC Converter

1. Prepare EC standard solution. (if there is no standard solution, prepare EC portable whose close to standard value)2. Prepare “-” driver. (a kind of clock driver)3. Remove EC sensor from SW-1004E system.4. Put EC sensor into the standard solution or the solution which is checked with EC portable.5. Open cabinet in front of system and find the EC converter.6. Turn on system power and check the ‘Current EC” value of the initial screen.7. Adjust by turn right or left “SPAN” volume in the center of the EC converter by using driver.8. Set to the EC value which is checked with standard solution or EC portable.9. Adjust exactly by repeating more than 3 times.※ Never adjust other volumes of EC converter.※ Put the EC sensor into the solution as deep as possible.

EC Sensor Management Tip

1. Check and adjust ZERO by using standard solution once a month.

2. Clean the sensor surface by smooth cloth once a week.
