- Perform a measurement, the result should be e.g. 0.0 °Brix, 0 ppt, etc. (with the respective accuracy).
If the check fails, take corrective actions until the check is valid again:
- Check the quality of your reference liquid (distilled water).
- Clean the measuring prism and sample well thoroughly. To remove your samples you can also use alcohol or a solvent suitable for your sample.
- Perform a zero adjustment (Go to "Settings" - "Manage my devices" - "SmartRef Connected" - "Zero Adjustment")
