Description
Outputs the analog signal (specified in the current
separation method, or default separation method) to a
device such as an integrator or strip chart recorder (see
"Set I/O parameter values" on page
one of the following signals as the chart out signal:
• Flow rate
• System pressure
• Sample loop pressure
• Primary head pressure
• Composition (%A, %B, %C, %D)
• Sample temperature
• Column temperature
• Degasser vacuum
The table, below, lists the output signal conditions for
each of these parameters.
