Page 3: Safety Precautions
Do not leave the probe in the soil. If the probe is left in the ground, it can loose intimate contact with the soil resulting in incorrect reading. Guidebook The Aquaterr Instruments Guidebook explains how to use your meter to optimize your irrigation practices by helping you to look at the relationship between plants, soil and moisture. - Page 4 AQUATERR INSTRUMENTS Moisture and Multimeter Owner’s Manual Your patented Aquaterr Instruments Meter can assist you in effective soil-water management. It is light weight and portable providing instantaneous moisture and salinity readings in rapid succession at multiple sites and depths. It is virtually free from errors ordinarily caused by temperature, pH, dissolved salts and metallic ions.
- Page 5 FOUR CRITICAL STEPS While your Meter is easy to use, four important steps must be performed to ensure repeatable results. 1. CALIBRATE the moisture section in IRRIGATION water. Check its calibration every several hours. 2. WIPE THE PROBE with a towel between EACH test, remove all excess dirt. Dirt carryover will cause errors in future readings.
- Page 6 COMMON PROBLEMS (Soil Moisture Measurements) PROBLEMS Insert probe, press the dirt around the Widely varying readings, due to lack of Soil probe by standing close to both sides of the Compaction caused by wiggling the probe. probe. Then take reading. Lower/higher than expected readings.

- Page 8 EVALUATING THE MOISTURE MEASUREMENTS It is important to remember that your Meter is a capacitance moisture meter. Capacitance meters “look” at the air-water ratio in the soil. Thus, soil compaction has an affect on the reading. A more compact soil will hold less air than a loose soil (like a sponge). This means that the more compact soil will have higher readings than a loose soil.

- Page 10 CALIBRATING THE SALINITY FUNCTION (Salinity Multimeter) Caution: This should only be done as a last resort after you have tried everything else and you are certain that it is required. We have provided two methods of calibrating the salinity function. The first method is more convenient for laboratory or controlled conditions;...
