Keep the measurement cell and grinder-compressor clean and use the correct crop calibration and sample quantity for every test. Check the grinder blade and feeder ring if grinding becomes difficult or readings become inconsistent, and remove the battery during long periods of storage. The Grainmaster i2-S supports Bluetooth connectivity and the Grainmaster app; make sure the meter is running current firmware if app connectivity is required. Regular servicing and calibration checks help maintain consistent results.
