7.3.3 Measurement Display

The center left of the screen contains the measurement results.

• VWC — This section shows volumetric water content in percent. This

value is automatically compensated for varying soil conditions. If the

measurement is out of range the display will show “---” in this position.

• PER — The average period measured -- expressed in microseconds.

Under the sensor readings are displayed model number and rod length of the

sensor used (in this case “CS658 20cm”). This is updated with each

measurement.

If the water content sensor is not properly connected or is malfunctioning, the

display will show “SENSOR TIMEOUT”.
