Enpac Ex Parameters 107
Instrument Configuration
Parameters The Instrument Configuration parameters set up the data collection options. These
parameters affect the measurement, the data collection process, and the way data is
displayed in the Enpac Ex. The Enpac Ex stores these settings even when the unit is
powered off.
Refer to Selecting the Data Collection Options on page 78 for
more information.

Parameter Name Description Values/Comments
Freq. Units The frequency units for displaying spectra/FFT data
in the data collector. This parameter is initially set to
the default frequency (Hz or CPM) in Emonitor when
you load a list.
• Hz - Displays spectra in Hertz, cycles per second.
• CPM - Displays spectra in cycles per minute.
• Orders - Displays spectra in orders of the
operating speed. This is used only when order
normalized or phase data is collected using a
tachometer or strobe to trigger data collection.
Options: Hz (default)
CPM
Orders
Auto Store Controls the number of key presses required to
accept data.
• On - The Enpac Ex automatically accepts both the
overall and signature measurements and proceeds
to the next point in the list. The overall
measurement is accepted based on an algorithm.
The algorithm is based on a percent fluctuation
over a period of time (seconds). If the overall stays
with the % specified by Percent for the number of
seconds specified with Time, the overall
magnitude is accepted.
• Off - You must press READ/OK to accept the
overall measurement, and then press READ/OK
again to accept the signature measurement.
Options: On
Off
Time The number of seconds that input signal must be
steady for Auto Store to occur. Default value is 5 seconds
Note: This parameter is only used
when Auto Store is set to "On."
Percent The fluctuation percent for Auto Store to occur. Default value is 10%
Note: This parameter is only used
when Auto Store is set to "On."
Auto Advance Determines whether the Enpac Ex automatically
moves forward to the next point in the list after
collecting data for the current point.
• On - Enpac Ex automatically moves forward to the
next point in the list after collecting data for the
current point. No spectrum is displayed.
• Off -Enpac Ex displays a spectrum after collecting
data for the current point.
Options: On
Off (default)
