Troubleshooting
- Primary Test: In air, the Soil Moisture Sensor should read somewhere between -5% and -50%. Grab the sensing portion with your hand, and the reading should go up to somewhere between 10% and 50%.

Calibration
Calibrate? Usually, no. Possible exceptions: you are testing soil with high concentrations of salt, sand, or organic matter; very precise readings are required. See detailed calibration instruction in the user manual. For additional information on sensor calibration, see How do I calibrate my sensor?
