I saw the "Little mismatch".
One plant was measured with 2 devices.
Must I calibrate?
The leaf thickness gauge comes calibrated from the factory. However, we have noticed there can be an issue where the orientation with which the magnet (use in the thickness measurements) was installed can cause some problems. We are looking at making some changes to the firmware and calibration process to solve this issue.
We will give you updates as we make progress.
