When using the
RheoVac
software on a PC, the software may give you a “Communication Error or
Message.” Use the Table VII to determine the source of this message and appropriate action.
Note: If the
RheoVac
instrument is operating without message indications but output readings are
questionable, please send to Intek by telefax or e-mail the following plant data: turbine back pressure,
hot well temperature, load, and inlet and outlet circulation water temperatures, along with at least 24
hours of data from the
RheoVac
instrument/probe for the same time period.
