24.2.4. –Status Messages
The top line of this screen can display four different status messages. The messages are:
“Waiting for Data” -This message is displayed until in-range RPM, IPS, and Phase Angle
readings are recorded by the analyzer. The only way to exit the screen while this message is
displayed is to use the [F0] “Back Up” key.
“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. The only way
to exit the screen while this message is displayed is to use the [F0] “Back Up” key.
“Data Quality: Fair” (highlighted yellow) -This message indicates that data is being collected,
but there are not enough samples yet to confirm good quality readings. You can press [OK] to
accept a reading at this point, but the quality of the measurement may be reduced.
“Complete! Press OK” (highlighted green) -This message will appear when a minimum number
of consistent samples have 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.
