10.1.11.3. A data acquisition screen similar to the one shown below will be displayed. If
you are unfamiliar with reading this screen, see Chapter 24 of this manual,
“Reading Spectrum and Scales”. Allow the analyzer to average the acquired data
until the indications are stable. The term STABLE is used here to indicate that
the Average indications are not widely fluctuating and that the Error indication is
as low as possible and not increasing. Press [F1] “Reset”, to clear the averaged
data to this point and begin the averaging process anew or press [OK] to stop the
acquisition and proceed.
The top line of this screen can display three different status messages. The
messages are:
“
Waiting for Data ” – This message is displayed until in-range RPM, Vibration,
and Phase Angle readings are recorded by the analyzer.
“
Acquiring Data ” – This message is displayed during data acquisition. As long
as the data remains in-range, the analyzer will add each new sample to the
running average.
“
Data Quality Fair ” – This message is displayed when enough data has been
collected to continue. However, the data collected at this point may not be the best
to provide an optimum solution. It is recommended to wait for the “Complete!
Press OK” message before proceeding.
“
Complete! Press OK ” – This message will appear when the optimum number of
consistent samples has been collected. Allow the unit to collect data as long as
the error continues to decrease. This will insure you have the most accurate data
possible. Use the [OK] key to exit this screen and store the reading.
The text below the “Current” heading indicates the RPM, Vibration, and Phase
Angle from the latest collected sample. These values will change as the
individual readings are collected. The RPM will be the currently recorded speed
value. For Run 1 the “RPM” heading itself will blink “HIGH” or “LOW” if the
current RPM is more than +/- 200 RPM from the RPM defined in a Fan/Turbine
Balance setup. For subsequent runs, the HIGH/LOW warning will appear if the
value is +/- 50 RPM from the value recorded during Run 1.
Use the [F1] “Reset” key as a way to validate the measurement or to reset the
average. Use the [F3] “+/- Pol.” key to reverse the polarity of the Tach Signal. If
the Current RPM is erratic at a stable engine speed, press this key in an attempt to
