4.4 Interaction between the HygroMet MP and probe functions
It is important to note that when used together, the HygroMet MP transmitter and HC2 probe (HygroClip 2)
constitute a 2-component system. Each system component has its own microprocessor, firmware and
functions. Some of these functions are unique to each system component. Other functions are found in both
components.
The functions and settings of the HygroMet MP (HM) and HygroClip 2 probe (HC2) operate together as
indicated below:
