Page 3: Basic Operation
Basic Operation Power up/down The soil moisture sensor reader is powered on and off with the ON/OFF button. The meter will initially display the battery level and firmware version. It will then transition to sensor reading mode. The initial mode displayed will be the mode that was active when the meter was powered off. - Page 4 3. Watermark: Displays the soil moisture tension in kPa. Reader must be connected to a WatchDog compatible Watermark sensor (see Watermark Sensors, p 5). 116.0 kP WatrMark Sample Watermark LCD Screen 4. Temperature: This mode is valid when a temperature sen- sor or an SMEC300 sensor is connected to the reader.

Taking readings The display is dynamic and will be continually updated as conditions surrounding the sensor change. Because the meter automatically refreshes itself, occasionally you will notice that the LCD will spontaneously restart and display the initial power-up screen. This happens if a sensor is being inserted or withdrawn at the precise moment when the meter is taking a reading. -
Page 6: Calibration Procedure
Calibrating the SMEC 300 EC Sensor The EC sensor of the SMEC300 sensor has an internal constant that can be adjusted by the user to correct for sensor drift. To calibrate the sensor, you will need a container wide enough to accom- modate the sensor and tall enough so the sensor can be immersed to the midway point of the sen- sor molding. -

calibration is complete, the internal sensor constant will not be modified and this step should be repeated. 6. Disconnect the sensor plug. 7. Rinse and dry the sensor. Take care not to touch the EC sensor pads with your fingers. 8. - Page 8 Type: Electrical Equipment for Measurement, Control, and Laboratory Use The undersigned hereby declares, on behalf of Spectrum Technologies, Inc. of Aurora, Illinois, USA, that the above referenced product, to which this declaration relates, is in conformity with the provisions of:...
