OPERATION
RHS Control is a PC program (available on Windows and Linux) which allows the user to operate the humidity
generator system. Operation may be manual, through direct entry of desired setpoints, or automatically, through a
series of preprogrammed, user selectable setpoints and times.
In addition to entering setpoints for control, the program offers visualization of resulting data in real-time both in
numerical and graphical formats. It also allows for connection to other instruments such as those connected as
Units Under Test, or UUT’s, provided they have a serial data port. For those instruments with a serial data port, a
customized protocol description in the form of a .json file is used to make the data connection. These .json files are
text files utilizing our RHS Descriptor Language to define the instrument protocol, commands, and data
presentation method. These instrument specific files may be created and/or modified by end users, or they may be
obtained from RH Systems for particular instruments. While these descriptor files are available for RH Systems
brand products, they can also be created for a wide variety of instruments and are not limited by brand and model.
The main requirement is that the instrument be connected via a serial interface that can respond to command
requests in a consistent manner.
