PROBLEMS

Battery indicator is on

EC of soil matches EC of the water

Salinity is lower than expected

It is important to keep the wings of the probe clean and free of dirt and buildup. It is suggested

that every couple of weeks, the wings be polished with a plastic abrasive pad to remove

buildup. When cleaning it is also important not to abrade the plastic area.

SOLUTIONS

Replace the battery quickly. Remove the

battery cover and replace with a 9 volt

battery.

Give more time for the soil to come to

equilibrium. Do not test so soon after

irrigation.

Check soil moisture level. If the soil

moisture level is below 65% the readings

need to be calibrated with a soil sampling

test. Salt will precipitate in the soil's free

(available) water, and will saturate out in

this soil/water mixture. There is not

enough water present for the salts to mix

with the water evenly. For this reason, a

sample of the soil must be taken, then the

moisture and salt content of the soil

sample has to be determined, and the

results can be used to calibrate the "EC"

readings of the EC-300.
