1. Introduction The SMM Soil Moisture Meter is a complete system for collecting and storing data from up to ten sensors in the field or in the laboratory. The SMM is equipped with an internal battery which provides power to the instrument as well as the sensors. A fully charged battery should have the capacity to provide several hours of data collection in the field before recharging is required. -

6. Turn the Instrument On To turn on/charge your SMM Soil Moisture Meter connect the Instrument to a computer via a USB cable. Alternatively, the SMM can either be turned on manually by pressing the power button or automatically by connecting an external power supply. -
Page 12: Connect To The Instrument
7. Connect to the Instrument Connect Via USB Connect the USB cable to the instrument. Open ICT Instrument software and click “Search for Devices”, then click the named instrument from the Available Devices within the Device Selection Window. Click the connect button or double-click the instrument from the list. Enabling better global research outcomes in soil, plant &... -
Page 13: Connect Via Mcc Mini
Connect via MCC Mini Ensure that the SMM is on. Connect the MCC Mini to your computer, open ICT Combined Instrument software. Tick ‘Auto RF Discover’ and then Search for Devices. The MCC Mini should appear on the list, it will then automatically search for nearby ICT Instruments. -
Page 14: Set The Measurement Parameters
8. Set the Measurement Parameters When you connect to an instrument, the Channels screen will be displayed. This shows the current measurement status, when the next measurement will take place, the currently configured channels, instrument serial number/name/comment, battery status, external power status, SD card status, and the instrument time and date. -
Page 15: Configuration
In manual mode a measurement will be taken whenever the Start Measurement button on the Channels screen is clicked. If the SMM is in live mode, measurements can be taken from every 250ms to 60 seconds. ICT recommend connecting the SMM to a continuous external power supply (eg: a CH24) when using live mode, as this significantly increases the power usage of the logger. -
Page 16: Measurement Suspend And Time Delay
8.1.3 Measurement Suspend and Time Delay This option allows you to set a time for the instrument to begin logging. This can be handy for completely setting up an instrument prior to installation in the field. Logging can be delayed for up to 24 hours (23:59:59), at which point it will begin to log at the set interval. -
Page 17: Conversion Configuration
Conversion Configuration allows conversion scripts and tables to be added. These can be assigned to a channel in Channel Configuration. When your instrument arrives from ICT International it will be preloaded with all necessary tables and/or scripts. 8.2.3 Advanced Configuration The Advanced Configuration section is used to combine 2 single-ended inputs into a single differential input. -
Page 18: Lookup Tables And Scripts
Lookup Tables commonly used for the ICT Instrument described in this manual are found in Appendix 11.2. If you cannot find the table or script corresponding to your sensor please contact ICT International. Lookup tables can be imported/exported as CSV, where column A is mV and column B is the converted value. - Page 19 User Scripts allow the conversion of millivolt (mV) sensor output into meaningful measurements, and are particularly useful if the relationship between mV and the converted value is non-linear. Scripts can also be used for linear relationships. User scripts can be imported/exported as .uscr files, which can be opened in notepad or any similar program.

Page 21: Download Data
10. Download Data The Data tab can be used for basic data visualisation, SD card management, and to download data files from the instrument. Data is stored on the MicroSD card in csv format. The MicroSD card can also be removed from the logger and read by a computer. - Page 22 Manage SD displays the content of the instrument SD card. Refresh List loads the list of files currently present on the SD card. Download File downloads the selected file to the location of your choice. Rename File allows you to change the name of the selected file. Note that if the instrument data file is renamed a new file will be created for measurements from that point onward.

The MP406 can be installed by drilling a close-fitting hole into the soil profile, (either at an angle or vertically – suitable augers are available from ICT International) or it can be installed horizontally from a larger hole or soil pit. Care must be taken to ensure the needles are fully in contact with the soil profile after installation. -
Page 28: Theory Of Operation
2. Theory of Operation The MP406 has a high frequency moisture detector which uses the standing wave principle to indicate the ratio of two or more substances forming a body of material, each substance having a different electric constant (Ka). The moisture measurement of the material is based upon the fact that in a water/soil/air matrix, the dielectric constant is dominated by the amount of water present. - Page 29 The results from measurement of the absolute volumetric soil water percent (VSW%) using the MP406 when compared with TDR technology are given in Figure 2. This result is typical of the results obtained from comparative testing of the MP406 compared to TDR technology for a wide range of agricultural soils.

Page 30: Linear Calibration
3. Calibration General The results obtained from measurement of the absolute volumetric soil water content (VSW%) using the MP406 are expected to be within ± 2–5% of the actual soil moisture as determined in the laboratory by gravimetric and volumetric methods of determination. Recalibration is not expected to be necessary for most applications in most commonly occurring agricultural soils. -
