Sensor calibration
The electrical properties of different materials can be quite diverse and it is often
necessary to calibrate the moisture sensors to suit different materials.
Hydro-View allows the calibration values for up to ten different materials to be stored
internally in a material table which can then be recalled instantly by using a Material in use
number. This number can be selected either locally at the keypad or remotely using the
serial ports.
The Hydro-View uses a two-point calibration method which requires you to enter values
from two samples of material at different moisture contents. A minimum difference of 1%
in moisture content between the two samples is required to reduce possible calibration
errors, although a larger difference is preferable.
