stabilize the reading. This option may be necessary when some of the Tooth
settings (Mod Tth or Adj Tth) are selected on some engines.
NOTE
While collecting data, if the amplitude is high, the Error number will decrease toward 0.00 very
rapidly. This indicates the number of errors in the indication are averaged out. As the amplitude
is decreased in the balancing process on subsequent runs, the Error indication may not drop as
rapidly and will most likely not reach a 0.00 reading because the amplitude is so low. In lower
amplitude situations, watch for the Error indication to be stable as an indication of acceptable
data rather than waiting for it to decrease further.

10.1.12.1.
The Review Prior Run(s) Data screen, shown below, will be displayed showing
the RPM, Vib (amplitude) and Deg (phase angle) collected on all runs up to this
point. Pressing the [
] or [
] keys will allow you to navigate through the
readings from all runs of the current job. Use the text on the first line to
determine the run number. While viewing the current run, the currently active
RPM field will have its color scheme inverted. Use the [
] and [
] keys to move
the highlighted field. To re-take measurements for the current speed, press the
[F1] “RetakeOne” key. To retake readings for all speeds, use the [F2]
“RetakeAll” key. Press [F5] “Continue” to accept the current measurements and
continue.
