GENERAL OVERVIEW Thank you for purchasing a FieldScout TDR 350 Soil Moisture Meter. This manual describes the meter’s general features and operations. Soil moisture is a critical, and potentially highly valuable component of the soil environment. Time domain reflectometry (TDR) is a proven technology for quickly and accurately determining volumetric water content (VWC) in soil. Electrical conductivity (EC) is a function of the moisture and salt in the soil and can be factored out to increase the accuracy of VWC measurements. -

Page 8: Setup
SETUP GNSS (Location) Settings GNSS Location adds the ability to log global position coordinates with measurements to aid in irrigation mapping of crops and turf greens. Location references are stored with the measurement in the data log and can be uploaded to the Cloud through the SpecConnect FieldScout Mobile App option. - Page 9 Intial Use: During the first three days of use, the meter’s GNSS receiver will build an internal satellite record used for tracking and accuracy. Accuracy during this time may appear low, will depend on the accuracy of available satellite systems, and can vary within 10 meters.

Page 14: Maintenance
The salinity level of soil is an important component of irrigation and nutrient management. The source of soil salts ranges from the original patent material, additions from natural sources and management activity. High salt concentration in the soil has a negative effect as plant roots cannot bring in sufficient soil moisture, However, fertilizer exists as salt ions in that same soil solution. -
Page 15: Updating & Calibration
Display Installation Reconnect the sensor cable to the 3.5mm connector on the back of the display module if previously removed. Insert the foam spacer back behind the sensor cable if previously removed. The split end fits around the sensor cable molding. If equipped with the IR temperature sensor option, attach it to the smaller diameter connector. - Page 16 Calibration The FieldScout TDR is fully calibrated at the factory. Further calibration is not required, nor recommended. The meter has internal calibrations that will work for many soil types. Each meter will have a small difference in how it responds to identical soil conditions.
