Autonomous Sampling Commands (continued)
ProcessRealTime=x x= Y: Apply alignment, filtering, and
conductivity cell thermal mass corrections
to real-time data. Only applies if
OutputFormat=1 or 3. Default.
x= N: Do not apply corrections to data.
TAdvance=x x= Time to advance temperature data
relative to conductivity and pressure data.
Range 0 to 0.125 seconds; default
0.0625 seconds. Only applies if
ProcessRealTime=Y and
OutputFormat=1 or 3.
Alpha=x x= Conductivity cell thermal mass alpha
correction. Range 0.02 to 0.05; default
0.03. Only applies if ProcessRealTime=Y
and OutputFormat=1 or 3.
Tau=x x= Conductivity cell thermal mass tau
correction. Range 5.0 to 10.0; default 7.0.
Only applies if ProcessRealTime=Y and
OutputFormat=1 or 3.
AutoRun=x x=N: Wait for a command when power is
applied. Default.
x=Y: Start autonomous sampling
automatically when power is applied.
Start Start autonomous sampling now
(applicable if AutoRun=N or if you just
sent AutoRun=Y).
Stop Stop autonomous sampling.
Press Enter key to get S> prompt
before entering Stop.
Notes:
• You may need to send Stop several
times to get the FastCAT to respond.
• You can also stop autonomous
sampling by clicking the Stop key on
the Toolbar, typing Ctrl Z, or
removing power.
Note:
After you send AutoRun=Y,
to start sampling immediately:
• turn power off and then on again, or
• send Start.
Notes:
• See Real-Time Data Corrections for
detailed explanations of
ProcessRealTime=, TAdvance=,
Alpha=, and Tau=.
• If ProcessRealTime=Y but
OutputFormat=0 or 2 (output raw
hex or raw decimal data), the status
reply shows:
real-time temperature and
conductivity correction
enabled, not applied to raw
data,
and the FastCAT does not perform
real-time corrections.
