For any system, from the time an experiment starts,
it takes a while for any system transients to die out.
Therefore, the experiment needs to run for at least
long enough for the transients to die out
before the "steady oscillation" condition can be observed in the output.
THEN, the experiment needs to run long enough to get
AT LEAST one full cycle of the sine curve.
So, let's say that your frequency is "f", then your
Sine wave has a period of 1/f = T
Add this T to whatever the minimum suggestions are below.
For the Pressure or Speed system, from the time an experiment starts,
it takes about 2 or 3 seconds for any system transients to die out.
Therefore, the experiment needs to run for at least about 5 seconds
MINIMUM before you get steady socillation data from the system.
Lab Wizard suggestion for Pressure or Speed:
MINIMUM Length of experiment (sec) of 5 or 10 seconds
For the Flow system, from the time an experiment starts,
it takes about 5 or 6 seconds for any system transients to die out.
Therefore, the experiment needs to run for at least about 10 seconds
MINIMUM before you get steady socillation data from the system.
Lab Wizard suggestion for Flow:
MINIMUM Length of experiment (sec) of 10 or 15 seconds
For the Voltage system, from the time an experiment starts,
it takes about 10 seconds for any system transients to die out.
Therefore, the experiment needs to run for at least about 15 seconds
MINIMUM before you get steady socillation data from the system.
Lab Wizard suggestion for Voltage:
MINIMUM Length of experiment (sec) of 15 or 20 seconds
For the Level system, from the time an experiment starts,
(using the small tank)
it takes about 3 minutes for any system transients to die out.
Therefore, the experiment needs to run for at least about 5 minutes
MINIMUM before you get steady socillation data from the system.
Lab Wizard suggestion for Level (small tank):
MINIMUM Length of experiment (min) of 5 or 10 minutes
The large tank takes about 2 to 5 times as long.
Adjust times accordingly.
