  1. Calibration

Check calibration status

To check the Calibrationstatus you must have access to the user interface. If this is not the case, see here how to do it:Access to the user interface

The easiest way to check the calibration status is to place the Hydrom in 20 degree water and access the Configuration-View.

If the hydrom now shows a value close to 0P at 20 degrees water temperature, then the hydrom is calibrated.

If the value is greater than 15, it is likely that Gravity has been set as the unit. This can be changed by selecting "Plato" under Tilt-Unit in Settings.

If the hydrom is not calibrated, there are three possibilities.

  1. plain water calibration The Hydrom measures the actual angle in the water and calculates an approximation to the actual calibration formula from the known relationships.

  2. reference calibration The hydrom is placed in a reference liquid and when the density changes, this is measured with a reference meter and entered into the hydrom. This step must then be repeated 7 times to determine the formula. Yeast or sugar can be used to change the density.
