4-20mA Outputs
The P-
600 Salt in Crude Analyzer’s analog outputs (Channel 1 standard; Channel 2 optional) can be
programmed to output various types of information, as well as the range of the analog signal and an
offset.
•
Type
—
This menu item allows you to select the type of information that will be output using the
selected analog signal. The choices are Off, SiC 1, SiC 2, Cell Temperature, Conductance, and
Validation.
•
4 mA
—
This menu item is used to set the value at which a 4mA signal will be output.
•
20 mA
—
This menu item is used to set the value at which a 20mA signal will be output.
•
Offset
—
This menu selection allows you to offset the analog output signal by the programmed
value. For example, if the offset is set to +1.5, the Analyzer will generate an analog signal
corresponding to 10.5 when the actual measured (and displayed) concentration value is 9.0.
Graphics
These menu items allow you to select the measurement information which will be displayed in the
graphical data display section of the Main Run screen. The choices are:
•
Salt in Crude

•
Conductance
–
Conductance measurement result.
•
Validation
–
Validation measurement results.
