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.
