Technical Support 3
The Enpac Ex is a full featured data collector designed to collect dynamic
vibration data inside hazardous areas. It is capable of operating as a
stand-alone instrument or it can be interfaced with Emonitor software for
uploading/downloading applications or subsequent data analysis. While the
Enpac Ex is ideal for noise and vibration analysis, it can also be used for a
variety of other applications, such as Rolling-Element Bearing Analysis.
With the combination of the Emonitor software and the Enpac Ex, you can:
®
• Create lists of measurement definitions for data collection.
• Load lists from Emonitor into the Enpac Ex.
• Collect magnitude, process, spectrum, time, and phase data.
• View selected alarms with the data. The Enpac Ex alerts you when a
measurement exceeds an alarm.
• Select inspection codes to store with a measurement, documenting the
condition of the machine.
• Unload the data from the Enpac Ex directly into the Emonitor database,
along with any inspection codes and unscheduled measurements.
In addition, Emonitor can optimize your data collection by combining
measurement definitions at a location. For example, Emonitor can combine
two magnitude and one spectrum measurement definition so that the list
appears to contain only a single measurement. This allows you to collect all
three measurements at one time, minimizing the time you spend collecting
data.

Setting Up Measurements
This chapter describes setting up the measurement definitions in Emonitor to
use with the Enpac Ex. Measurement definitions define how to collect and
store measurements. You can create several different types of measurement
definitions at each location. Emonitor can then take advantage of the abilities
of your data collector by combining some of the measurement definitions
when you load them into the data collector. By combining measurements,
Emonitor can shorten the data collection time.
Chapter 3 also describes how Emonitor and the Enpac Ex handle alarms, lists,
and inspection codes.

Measurement Definition Options
These topics describe the available selections for setting up measurement
definitions in Emonitor. You determine these selections by selecting Too ls >
Set Active Collectors in Emonitor.
Figure 3.1 Set active collectors
The names of the active data
collectors appear in inverse
text
IMPORTANT
If no data collectors are active, the selections that appear in
the Measurement Definition pane are the ones available to
ALL data collectors. If only the Enpac is active, then only
the valid choices for the Enpac appear in the lists. If the
Enpac and other data collectors are active at the same time,
you see the selections that are common to all data
collectors that are active. Therefore, you may not see all the
selections available for the Enpac.
In some cases both Emonitor and Enpac Ex support certain options. In other
cases, Emonitor can support an option that the Enpac Ex cannot support. For
example, Emonitor can apply a software high pass filter to the data after it
unloads the data from the Enpac Ex. This allows you to use a filter that is not
available in the Enpac Ex.
Measurement Types
Emonitor and Enpac Ex support the following measurement definition types:
• Magnitude - This measurement type is a single value representing the
total energy of a measurement. For example, a vibration magnitude
represents the total energy in a vibration spectrum. The Enpac Ex can
also collect magnitude+phase measurements, for the first through the
eighth orders.
• Numeric - Manual entry or DC voltage measurement of an overall value
such as temperature, pressure, flow rate, operating speed, or proximity
probe gap readings.
• Spectrum - Frequency domain measurement of frequency vs. amplitude,
usually for velocity or acceleration. The Enpac Ex can collect phase with
spectrum measurement definitions.
Publication GMSI00-UM001A-EN-E - February 2005
Setting Up Measurements 33
• Time Waveform - Time domain measurement of time vs. amplitude,
usually for displacement, velocity, or acceleration.
Remember that the available measurement types in Emonitor depend on the
active collectors you select with the Tools > Set Active Collectors. If you
have two or more active data collectors, you may not see all the selections
available for the Enpac Ex.
Measurement Filters
Emonitor and Enpac Ex each support certain measurement filters. Some of
the filters are supported in both Emonitor and Enpac Ex. You can define
custom band filters (high pass, low pass, band pass) by creating a new band
filter using Setup > Band Filter. You can choose to use a filter in the Enpac
Ex by selecting the Analog or Rss (digital) option when you define a filter.

34 Setting Up Measurements
IMPORTANT
gSE filters
Filters in Emonitor are referred to as software filters.
Filters in data collectors are referred to as hardware filters.
Hardware filters alter the signal in the Enpac Ex. Emonitor
software filters alter the signal (data representing the signal)
after you unload the data into Emonitor. In general, if the
filter you want to use is available in both Emonitor and in
the data collector, it is to your advantage to use the
hardware filter in the data collector.
Hardware filters have the following advantage:
They can remove low frequency, high amplitude signal
components that would dominate the dynamic range in the
data collector. This results in improved amplitude
resolution of the remaining signal range.
Software filters have the following advantage:
If there is no corresponding filter in the data collector, or
you choose not to use it, Emonitor can apply a digital filter
after you unload the data from the data collector.
Use a gSE filter to detect bearing and other component defects. The gSE
filters provide a demodulated measurement similar to the "envelope"
measurements in other instruments. You can use gSE filters with the following
measurement definitions:

ESP filters
Use an Envelope Spectrum Processing (ESP) filter to detect bearing and other
component defects. The ESP filters apply a band pass filter, envelope the time
domain signal, and then perform a frequency analysis on the result. ESP filters
are built into the Enpac Ex, and you cannot change them in Emonitor. You
can use ESP filters with the following measurement definitions:
• Magnitude
• Spectrum
The following ESP filters are available with Emonitor and the Enpac Ex.
0.6 to 1.25 kHz
1.25 to 2.5 kHz
2.5 to 5 kHz
5 to 10 kHz
10 to 20 kHz
TIP
Contact Technical Support for assistance in using the ESP
filters in Emonitor.
High pass filters
Use a high pass filter to remove high vibration, low frequency signal
components that would dominate the signal. Examples include structural
vibration or signal components generated by an integrator. The high pass filter
excludes all frequencies below a defined frequency. It allows, or passes,
frequencies above the defined frequency. You define these and other band
filters using Setup > Band Filter. You can use a high pass filter with the
following measurement definitions:
• Magnitude
• Spectrum
If you select Analog (as the data collector filter type) when you define a high
pass filter, the data collector uses one of the following filters determined by the
following formula.

Emonitor uses a high pass filter with one of the low frequency cutoff shown in
the table below. It uses the filter whose cutoff is greater than or equal to the
result of the formula.

Order (Magnitude) filters
Use order filters to define the bands around orders for magnitude and
magnitude+phase measurements. You define these filters using Setup > Band
Filter. You can use order filters with the following measurement definitions:
• Magnitude
• Spectrum
You can define and use order filters for the first through the eighth orders with
the Enpac Ex. If you specify the Maximum frequency in Orders, select
Analog and Order normalize when you define the orders filters, then the
Enpac calculates the orders from an external trigger. The Enpac Ex then uses
its own filters to calculate the magnitude and phase for the first through the
eighth orders. Emonitor calculates magnitude values (without phase) for
additional orders after you unload the data. Emonitor also calculates
magnitude values after you unload the data if you select None instead of
Analog.
IMPORTANT
If you want phase, remember to specify the Maximum
frequency (in Collection Specification dialog box) in
Orders, select Analog in the Band Filter Specification
dialog box and Order normalize in the Collection
Specification dialog box. Emonitor does not select these
options by default.
Default filters
There are also four default filters in Emonitor that map to specific filters in
Enpac Ex. The filters are High Frequency, Envelope, Smart HP, and Overall.
Publication GMSI00-UM001A-EN-E - February 2005
• High Frequency - Typically this filter maps to a high frequency filter in
the data collector and is available only for magnitude acceleration
measurements. In the Enpac Ex, it maps to the 5 kHz gSE filter.
• Envelope - Typically this filter maps to one of the gSE filters in the data
collector and is available for magnitude and spectrum acceleration
measurements. In the Enpac Ex, it maps to the 5 kHz gSE filter.
Setting Up Measurements 37
• Smart HP - (Smart High Pass) Typically this filter maps to a specific
high pass filter in the data collector and is available for magnitude,
spectrum, and time waveform measurements. In the Enpac Ex, it maps
to the Enpac filters shown in the table below, depending on the results
of comparing the filter choice to the formula below.
Emonitor uses the following formula.

IMPORTANT
The available filters in Emonitor depend on the data
collectors you select as active data collectors using Too l s >
Set Active Collectors. If you have two or more active data
collectors, you may not see all the selections available for
the Enpac. If you have no active data collectors, you see all
the selections for every data collector, not just the
selections for the Enpac.
RSS Overall
The Enpac Ex allows you to take a digital overall measurement, instead of
analog. This set up makes measurement collection faster. Be aware that this
Root Sum Squares (RSS) overall value is not as complete because it does not
include the power in the signal from below the first spectral bin or above the
highest spectral bin. Please note that the RSS overall values may not trend well
with analog overall measurements.
To use the RSS filter, you must create a Band Filter in Emonitor. Select
Setup > Band Filter and click New. Then select RSS (digital) as the filter
type.

IMPORTANT
Using the 0.36 Hz (21.6 CPM) low cutoff filter for
integrated measurements or the 0.18 Hz (10.8 CPM) low
cutoff filter for non-integrated measurements will always
cause the Enpac Ex to go into a long autorange mode.
Only use these filter settings when very low frequency data
is required.
Measurement Units
Emonitor and the Enpac Ex support many different measurement units. The
measurement units that appear in the Enpac Ex are text that depend on:
• The type of measurement definition
• The units for the measurement definition
• The transducer specification used in the collection specification for the
measurement definition
The Enpac Ex can collect data for English units, Metric units, or Decibels. It
uses the units that you select in Emonitor. You can select units from a single
system (e.g. English g’s, in/sec, etc.), or you can mix units from different

Emonitor and the Enpac Ex support the following input types.
• ICP Accel - Use for ICP accelerometers requiring current from a power
supply.
• AC Coupled - Use for AC voltage measurements and non-ICP
accelerometers.
• DC Coupled - Use for DC voltage measurements. This includes
numeric (process) measurements taken from a DC voltage output.

Measurement Window Types
The measurement window type is part of the collection specification (Setup >
Collection). See Figure 3.4 on page 40. You select the collection specification
when you set up the measurement definition.
Emonitor and the Enpac Ex support the following measurement window
types. In general, the Hanning measurement window provides the best
compromise of frequency and amplitude accuracy for most predictive
maintenance measurements.
• Hanning - A general purpose window to use on random type data
when frequency resolution is more important than amplitude accuracy.
Use this setting for most of your machinery monitoring activities.
• Rectangular - The data collector does not apply a window. Use this
only for transient signals that die out before the end of the time sample,
or for exactly periodic signals within the time sample.
• Flattop - Use this when amplitude accuracy is more important than
frequency resolution. In data with closely spaced peaks, a Flattop
window may smear the peaks together into one wide peak. Use this
setting for sinusoidal or calibration signals.
• Hamming - A general purpose window that is similar to the Hanning
window. It provides better frequency resolution but decreased amplitude
accuracy when compared to the Hanning window. You can use it to
separate close frequency components.
Publication GMSI00-UM001A-EN-E - February 2005
Measurement Signal Detection Types
The signal detection is part of the collection specification (Setup >
Collection). See Figure 3.4 on page 40. You select the collection specification
when you set up the measurement definition.
Emonitor and the Enpac Ex support the following signal detection types.
• None - Use for numeric measurements. None defaults to RMS when
applied to magnitude or spectrum measurement definition.
• RMS - Use for detection of voltage and current. For the frequency
domain, the dynamic signal is measured as the square root of the mean
of the square of the signal. This is the RMS amplitude of a sine wave at
the frequency of interest. For the time domain, the dynamic time signal
is squared, integrated over some time period, and then the square root is
taken.
• Peak - Use for detection of acceleration, velocity, and high frequency
energy. This is the peak (0 to maximum) amplitude of a sine wave at the
frequency of interest and is calculated from the RMS value.
Setting Up Measurements 43
• Peak-Peak - Use for detection of displacement; sometimes used for
high frequency energy. This is the peak-to-peak (minimum to
maximum) amplitude of a sine wave at the frequency of interest and is
calculated from the RMS value.
• True Peak - Use to detect impacts and random transients. The dynamic
time signal contains the absolute value of the largest peak (positive or
negative) within a specified time window. Returns a magnitude value
only. If used with a spectrum measurement, Emonitor uses a Peak signal
detection type instead. This value is not calculated but is measured
directly.
• True Peak-Peak - Use to detect impacts and random transients. The
dynamic time signal contains the absolute value of the largest peak to
peak distance within a specified time window. Returns a magnitude value
only. If used with a spectrum measurement, Emonitor uses a Peak-Peak
signal detection type instead. This value is not calculated but is measured
directly.
Measurement Maximum Frequencies
The measurement maximum frequency is part of the collection specification
(Setup > Collection). See Figure 3.4 on page 40. You select the collection
specification when you set up the measurement definition. Emonitor and the
Enpac Ex support the following maximum frequencies in Hz (CPM).

The number and type of averages are part of the collection specification

Emonitor and the Enpac Ex support the following number and types of
averages for data collection.
• Linear - Up to 4096 averages.
• Time Synchronous - Up to 255 averages, and requires a trigger.
Averaging is useful for reducing random errors. Random errors include
background vibration due to some source other than the machine being
measured. If you collect more averages, you have fewer random errors.
However, collecting more averages requires more time.
Overlap processing (Percent overlap) speeds up the averaging process. The
overlap amount determines how much of the time samples are overlapped for
successive averages. The greater the overlap, the faster the sample can be
collected. The disadvantage is that the greater the overlap, the less new data
there is, and the greater the influence of random errors.

Setting Up Measurement Definitions
The topics in this section describe setting up different types of measurement
definition in Emonitor for your data collector. The topics describe the way
Emonitor works with the Enpac Ex for each different type of measurement
definition.These include answers to questions such as:
• How does Emonitor handle measurement units and alarms available in
Emonitor but not supported in the Enpac Ex?
• How many orders of magnitude and phase can the Enpac Ex collect?
• How does the Enpac Ex support collecting a spectrum when a
magnitude measurement is in alarm?
Emonitor combines measurement definitions when it creates a load file from a
list of measurement definitions. For example, Emonitor can combine the
measurement definitions at a location so that the data collector collects all the
measurements at one time. This makes data collection faster and more
efficient since you do not have to start each measurement individually. For
more general information on setting up measurement definitions, see the
Emonitor online help.
Magnitude Measurement Definitions
Emonitor and the Enpac Ex support magnitude measurement definitions.
This topic lists the unique characteristics of the Enpac Ex that you may need
to know when setting up and collecting magnitude data.
Measurement units not supported in the Enpac Ex
• Magnitude measurement definitions with unit not supported by the
Enpac Ex map to units of USER (eus) in the data collector. This results
in a process (DC) voltage measurement.
• For a list of supported measurement units, see Measurement Units on
page 39.
Magnitude alarms in the Enpac Ex
• The Enpac Ex supports above, below, in window, and out of window
magnitude alarms.
• You must set Trigger to "Yes" for any magnitude alarms you want to
appear in the Enpac Ex during data collection.
• For more on how Emonitor combines alarms before sending them to
the Enpac Ex, see Alarms and the Data Collector on page 60.

Setting Up Measurements 47
Collecting magnitude measurements in multiple frequency bands
You can set up multiple measurement definitions at a location to collect
magnitude values for individual frequency bands. Use band filters to define the
different frequency bands in the measurement definitions. Make sure you
select None in the Band Filter dialog box. This forces the Enpac Ex to
collect a spectrum measurement. After you unload the measurement,
Emonitor calculates the magnitude values in the bands from the spectrum.
If your measurements include both magnitude and phase, the Enpac Ex can
collect up to eight orders. If your measurements include magnitude only, the
Enpac Ex can collect up to 200 orders.

Magnitude and Phase Measurements at Orders
Emonitor and the Enpac Ex support collecting the magnitude and phase at
orders. This topic describes the steps to set up measurement definitions to
collect magnitude and phase with the Enpac Ex. There are several things you
may need to know about collecting magnitude and phase at orders.
• You must select Also collect phase data in the collection specification
to collect phase.
• You must select Analog when you define orders filters. The Enpac Ex
automatically uses its internal order filters if you are collecting phase. If
you are collecting only magnitude values and you do not select this
option, the Enpac Ex collects a spectrum and Emonitor calculates the
magnitudes after unloading.
• When collecting magnitude and phase at orders, the Enpac Ex always
collects a spectrum measurement, and then calculates the magnitude
and phase values from the spectrum.
• The Enpac Ex can collect phase only at the first through eighth orders.
• The Enpac Ex can collect magnitude only at the first through the eighth
orders. If you request additional orders, Emonitor calculates magnitude
values at additional orders from the spectrum after unloading the data.
• The Enpac Ex may collect more orders than requested, but it does not
collect fewer than requested. Only the requested values are unloaded
into Emonitor.
Publication GMSI00-UM001A-EN-E - February 2005
Setting Up Measurements 49
• The Enpac Ex may display a phase value that differs from the value that
appears in Emonitor by up to one degree.
• Phase and magnitude measurements at orders require an external trigger
signal.
WARNING
Do not connect the Enpac Ex to an external trigger unless
the area is known to be nonhazardous.
To set up multiple measurement definitions for magnitude and phase
You create only one measurement definition for magnitude and phase at each
order. The Also collect phase data check box in the Collection
Specification dialog box determines whether you also want to collect phase as
well as magnitude data.
1. Create a new measurement definition by selecting "Magnitude" in the
Data Type column in the Measurement Definition pane.
2. Select the units for the measurement definition, using a dynamic unit
such as g’s, m/s2, ips, mm/s, mils, um, or V.
3. Select the measurement filter. To collect the magnitude and phase at an
order, select a band filter centered on the order. For example, select
(create if necessary) a first order band filter with a Low cutoff of 0.8
Orders, and a High cutoff of 1.2 Orders. See Measurement Filters on
page 33 for details and the examples on the following pages.
IMPORTANT
It is very important that order band filters be centered on
the order. For example, 0.7 to 1.3 orders, 0.8 to 1.2 orders,
0.9 to 1.1 orders, etc. If you do not center the band filters,
magnitude and phase readings may not be accurate.
4. Select the collection specification. You must select the Also collect
phase data check box in the Collection Specification dialog box so
the data collector collects phase at orders.
5. Select the storage specification. The first measurement definition is now
complete.
6. If you want to create more than one measurement, copy the
measurement definition by selecting the correct row and selecting Edit
> Copy.
Publication GMSI00-UM001A-EN-E - February 2005
50 Setting Up Measurements
7. Move down to the next empty row in the measurement definition
spreadsheet, and select Edit > Paste to paste the copied measurement
definition.
8. Edit the new measurement definition by changing the measurement
filter. Select a band filter centered on the next order.
9. Repeat steps 6 and 7 to create measurement definitions for the desired
orders. You can then include these measurement definitions in a list and
load it to the data collector. Remember that you must have a trigger
signal to collect magnitude and phase at an order.

Emonitor and the Enpac Ex support numeric measurement definitions. This
topic lists the unique characteristics of the Enpac Ex that you may need to
know when setting up and collecting numeric data.
Measurements units not supported in the Enpac Ex
• You can make a numeric measurement definition for any available
measurement unit by setting Data Type to "Numeric."
• Numeric measurement definitions with Input type set to "DC
Coupled" with units not supported by the Enpac Ex map to units of
USER (eus). The input type is part of the transducer specification that
you select for the collection specification. This results in a process (DC)
voltage measurement in the Enpac Ex.
• Numeric measurement definitions with Input type set to "Manual
Entry" not supported by the Enpac Ex map to USER (s) in the data
collector. These measurements require you to enter the value with the
Enpac Ex numeric key pad.
• For a list of support measurement units, see Measurement Units on
page 39.
Full scale values for numeric measurements in the Enpac Ex
• The full scale value in the Enpac Ex for a numeric measurement is
defined as ten times the value of the alarm or the baseline measurement.
• If no alarm or baseline measurement exists for the measurement in the
data collector, the Enpac Ex assumes a full scale value of 10,000.
• A full scale value of 10,000 can be a problem if you want to enter a very
large or very small value for the numeric measurement. For example,
you can not enter a value greater than the full scale value. If you enter a
value that is very small compared to the full scale, the Enpac Ex may
round the value off. If you enter 0.01 with a full scale value of 10,000,
the Enpac Ex stores it as a 0 (zero).

52 Setting Up Measurements
Temperature measurements
• Set up a temperature measurement definition by setting Data Type to
"Numeric" and Units to "RPM," "CPM," or "deg. C."
• Set up the temperature transducer in the Transducer Calibration
dialog box with Input type set to "DC Coupled" and Units to "deg. F"
or "deg. C." Make sure you enter the Calibration value that converts
the voltage to a temperature.
• Set up the collection specification to include a Signal detection of
"RMS."
Magnitude alarms in the Enpac Ex
You can use magnitude alarms with numeric measurements.
• The Enpac Ex supports above, below, in window, and out of window
magnitude alarms with numeric measurements.
• You must set Trigger to "Yes" for any alarms you want to appear in the
Enpac Ex during data collection.
• For more on how Emonitor combines alarms before sending them to
the Enpac Ex, see Alarms and the Data Collector on page 60.
Typical numeric measurement definitions
Figure 3.10 shows the setup for typical numeric measurement definitions.
Note that the first two measurements are numeric (DC) voltage measurements,
and the third is a numeric manual entry measurement.

Spectrum Measurement Definitions
Emonitor and the Enpac Ex support spectrum measurement definitions. This
topic lists the unique characteristics of the Enpac Ex that you may need to
know when setting up and collecting spectrum data.
• The Enpac Ex cannot collect phase with a spectrum measurement
definition. In other words, do NOT select the Also collect phase data
check box in the Collection Specification dialog box.
• You can choose to have the Enpac Ex collect a spectrum only if a
magnitude measurement at the same location is in alarm. Set the Collect
and store condition in the Edit Storage Specification dialog box to
"On Magnitude Alarm" for the storage specification for the spectrum
measurement definition.
Time synchronous averaging in the Enpac Ex
• Time synchronous averaging cancels out the effects of signals not
related to the synchronizing trigger. Time synchronous mechanical
effects include imbalance, misalignment, eccentricity of bent shafts,
blade passing, and gear meshing.
• Time synchronous averaging requires an external trigger.
WARNING
Do not connect the Enpac Ex to an external trigger unless
the area is known to be nonhazardous.
• Set up a Collection Specification with the averaging Type set to
"Time Synchronous" and enter the Number of averages. Use a large
number of averages (such as 20 or 30) to get the desired reduction in
non-synchronous effects. For more on supported averaging in the
Enpac Ex, see Number and Type of Averages on page 45.
Publication GMSI00-UM001A-EN-E - February 2005
54 Setting Up Measurements
Order normalized spectra in the Enpac Ex
• Order normalized spectrum measurements have a frequency axis based
on multiples of the running speed (orders). This quickly identifies the
frequency relationship between each measured vibration amplitude and
the running speed of the machine. It is particularly useful on variable
speed machinery.
• An order normalized spectrum measurement requires a trigger input to
the Enpac Ex.
WARNING
Do not connect the Enpac Ex to an external trigger unless
the area is known to be nonhazardous.
• Set up a Collection Specification with Window set to "Rectangular."
Select the Maximum frequency in "Orders," and make sure to select
the Order normalization option. The Averaging can be either "linear"
or "time synchronous," but should include at least four averages.
• The Enpac Ex may collect more orders than required. For example, if
you set the Maximum frequency to "10 Orders," the Enpac Ex may
collect more than ten orders. The Enpac Ex always collects at least the
number of orders you request in the Collection Specification.
• The Enpac Ex displays an order normalized spectrum. If the
Collection Specification dialog box has the Also collect phase check
box selected, and if the Maximum frequency is eight orders or less, the
table on the Enpac Ex screen shows the magnitude and phase values at
each order. If the Collection Specification dialog box does not have
the Also collect phase data check box selected, or if the Maximum
frequency is more than eight orders, the table on the Enpac Ex screen
shows magnitude values only. The Enpac Ex displays a maximum of
eight orders in the table.
Publication GMSI00-UM001A-EN-E - February 2005
If the table has eight orders or less, the Enpac Ex arrow keys move the
spectrum cursor. If the table has more than eight orders, the Enpac Ex
arrow keys scroll the table values.
Spectrum alarms in the Enpac Ex
The Enpac Ex supports band alarms with up to ten bands.
• You can have the data collector collect a spectrum measurement if a
magnitude alarm is in alarm. Set the Collect and store condition in the
Edit Storage Specification dialog box to "On Magnitude Alarm" for
the storage specification for the spectrum measurement definition.
Setting Up Measurements 55
• You must set Trigger to "Yes" for any alarms you want to appear in the
Enpac Ex during data collection. If you set Trigger to "Yes" for two or
more alarms for the same measurement definition, Emonitor combines
the alarms before sending the combined alarm to the Enpac Ex.
• For more on how Emonitor combines alarms before sending them to
the Enpac Ex, see Alarms and the Data Collector on page 60.
The Enpac Ex does not support spectrum alarms. You can still set up the
alarms for the spectrum measurement definitions. Emonitor tests the data
against the alarms after you unload the data.
Typical spectrum measurement definitions
Figure 3.11 shows the setup for typical spectrum measurement definitions.
The first is a standard spectrum, the second is an order normalized spectrum,
and the third is a time synchronous spectrum.

Time Waveform Measurement Definitions
Emonitor and the Enpac Ex support time waveform measurement definitions.
This topic lists the unique characteristics of the Enpac Ex that you may need
to know when setting up and collecting time waveform data.
• The Enpac Ex cannot collect phase with time waveform measurement
definitions.
• You can choose to have the Enpac Ex collect a time waveform only if a
magnitude measurement at the same location is in alarm. Set the Collect
and store condition in the Edit Storage Specification dialog box to
"On Magnitude Alarm" for the storage specification for the time
waveform measurement definition.
• The Enpac Ex supports integrated time waveform measurements
(single integration). This means you can collect a time waveform with
velocity units using an accelerometer or displacement units using a
velocity transducer.
• The length of the time waveform depends on the maximum frequency
you select in the collection specification.
• You can calculate the number of time samples from the number of
spectral lines (Collection Specification dialog box) using this formula.
time samples spectral lines 2.56×=
You can calculate the total time required to collect a time waveform
measurement from the Number of lines value and the Maximum
frequency value in the Collection Specification dialog box (Setup >
Collection Specification).
If your Maximum frequency is specified in CPM, convert CPM to
Hertz using this formula.

Emonitor and the Enpac Ex support measurement definitions with units of
volts (AC or DC). You can collect several different types of voltage
measurements. This topic shows the typical measurement definition setup for
three voltage measurements.
Voltage is similar to other units in that you can collect magnitude, numeric,
spectrum, and time waveform voltage measurements.

Combining Measurement Definitions for a Location
You can use Emonitor to set up many different measurement definitions for
data collection at a location. These can include magnitude, spectrum, time
waveform, and numeric measurements. You can then select the measurement
definitions you want to load to the data collector by creating a list of those
measurement definitions. When you want to load the data collector, Emonitor
builds a load file containing the measurement definitions in the list.
Emonitor combines measurement definitions at each location to make data
collection more efficient. This allows you to collect two or more
measurements automatically, without having to start each measurement
separately. The rules for combining measurement definitions depend on
Publication GMSI00-UM001A-EN-E - February 2005
60 Setting Up Measurements
several factors. In general, however, Emonitor can combine measurement
definitions at the same location when they have the same:
• Measurement units (part of the measurement definition)
• Measurement filter (part of the measurement definition)
• Transducer calibration and input type (from the transducer specification
used in the measurement definition’s collection specification)
In addition, there are some specialized cases that allow or prevent Emonitor
from combining measurement definitions from the same location when they
meet the above conditions.
• In general, Emonitor cannot combine a magnitude and a spectrum
measurement if they have different measurement filters.
• Emonitor can combine an envelope acceleration magnitude
measurement with a spectrum with the same units.
• Emonitor can combine a non-filtered measurement definition with a
high pass, low pass, or band filtered measurement when the band filter is
applied by Emonitor after the spectrum is unloaded.
• Emonitor can combine two signatures if they are the same type (time,
fixed frequency spectrum, order normalized spectrum) and the same
resolution.
Setting Up Alarms, Lists, and Inspection Codes
This section describes the way Emonitor loads alarms, lists, and inspection
codes into the Enpac Ex. For more information on alarms, lists, and
inspection codes, see the Emonitor online help.
Alarms and the Data Collector
Emonitor and the Enpac Ex support loading alarms with the list of
measurement definitions to the data collector.
Selecting alarms to load to the Enpac Ex
• If you want to load an alarm to the data collector with a measurement
definition, you must set Trigger to "Yes" in the Alarm spreadsheet in
Emonitor.
• If you set Trigger to "Yes" for two or more alarms for the same
measurement definition, Emonitor combines them to make a single
alarm.
Publication GMSI00-UM001A-EN-E - February 2005
Setting Up Measurements 61
Supported alarms with the Enpac Ex
This list describes alarms the Enpac Ex supports, alarms it does not support,
and substitutes for some of the unsupported alarms.
• The Enpac Ex supports above, below, in window, and out of window
magnitude alarms for magnitude and numeric measurements.
• You cannot select a magnitude out of window alarm in Emonitor. You
must create one by combining an above and a below alarm for the same
measurement definition. Emonitor creates an out of window alarm
when it builds the load file if both alarms are active.
• The Enpac Ex does not support spectrum (narrowband) alarms for
spectrum measurements. You can still set up spectrum alarms with
spectrum measurement definitions. Emonitor tests the measurements
against the alarms after you unload the data.
For unsupported alarms, Emonitor tests the measurements against the alarms
when you unload the data collector. This means that Emonitor always
accurately indicates when a measurement is in alarm, regardless of the number
or complexity of the alarm(s). This is true for all active alarms, regardless of
their trigger status.
Lists and the Data Collector
Emonitor and the Enpac Ex support loading lists of measurement definitions
to the data collector.
Inspection Codes and the Data Collector
Emonitor and the Enpac Ex support loading inspection codes to the data
collector.
Inspection code support in the Enpac Ex
• You can load inspection codes into the Enpac Ex only with a list.
• You can use only the inspection codes loaded with the list with
measurements in that list. This includes both measurements in a list and
unscheduled measurements associated with that list.
• You can load up to 100 inspection codes into the Enpac Ex. Emonitor
numbers the inspection codes from 1-100. The Enpac Ex numbers the
inspection codes from 00-99.
• The Enpac Ex displays the first 16 characters of each inspection code.
Publication GMSI00-UM001A-EN-E - February 2005
62 Setting Up Measurements
Loading inspection codes to the Enpac Ex
You can load and remove inspection codes.
• You must load the inspection codes when you load a list. You do this by
selecting Load inspection codes in the Load Options dialog box. If
you do not select this option, no inspection codes are available for
measurements from the list or for unscheduled measurements
associated with the list.
• You can remove the inspection codes from the Enpac Ex by initializing
the data collector.

a Pre-Defined Measurement on page 90
.
TIP
To have Emonitor put all unscheduled measurements in
one location, open the Load/Unload dialog box and click
the Unload Options button. Clear the Unscheduled
location smart mode check box.
If Emonitor can match the unscheduled data to an item in the Hierarchy Tree
and a location, then it stores the unscheduled data in measurement definitions
under that location. If Emonitor cannot match the data with an existing
measurement definition, then it creates a new measurement definition and
stores the data there.
If Emonitor cannot match an item in the Hierarchy Tree and a location, it
stores the data in the unscheduled destination, set with Too ls > S et
Unscheduled Dest.
Emonitor tries to match the collection specification for the measurement
definition. The rules for matching a collection specification are as follows.

Collecting a Spectrum Measurement
One of the most useful ways to display vibration signals is in a spectrum. The
spectrum displays the vibration signal level in relation to the frequencies at
which the vibration occurs.
To display a spectrum, the Enpac Ex analyzes the frequency components of
the signal and breaks this analysis down to a number of frequency bands where
the signal level for that band is represented by a single value. These bands are
called lines. A typical spectrum could have 400 lines although the Enpac Ex
allows you to select a smaller or larger number of lines. The higher the lines,
the higher the resolution, and the longer it takes the Enpac Ex to acquire the
data for a spectrum.
Lines of resolution, Fmax, and number of averages all affect the length of time
it takes to acquire and process a spectrum. You can control each of these setup
items either in your computer software for route measurements or on the User
screen for off route measurements. See Creating and Collecting a
User-Defined Point on page 92 for more information about off route
measurements.
1. Attach the transducer to the current location.
2. From the Data Collection screen, press READ/OK to begin ranging
the measurement.
IMPORTANT
If you previously collected a magnitude measurement for
the point, the spectrum measurement starts automatically
after you press READ/OK to accept the magnitude

operating speed. You use a tachometer signal measuring the operating speed to
collect phase data.
WARNING
Do not connect the tachometer to the Enpac Ex unless the
area is known to be nonhazardous.
Follow these steps to collect a spectrum for calculating additional magnitude
and phase values at orders of the operating speed.
1. Align the speed reference device, such as a tachometer, in the correct
direction and attach the vibration transducer properly.

Collecting Off Route Data
The Off Route program allows you to collect data that is not part of a list
(route). While collecting list data, you may notice some unusual conditions that
you want to analyze further. You may also want to collect data for undefined
points (points not in your database), or existing points that are not in your
current list (route).
The Enpac Ex always associates off route measurements with a list. If you
have not loaded a list into the Enpac Ex, the off route data is associated with
the Default Route. Off route measurements are stored at the current point.
The current point is defined by where you leave the regular route to take an off
route measurement. The Enpac Ex labels the off route measurements as
numbers. For example, the first off route measurement is labeled "1." This
number increments by one each time you collect an off route measurement.
To unload unscheduled measurements into the host software, you must have
first loaded a list so that the unscheduled measurements can be unloaded with
that list.
Methods for Collecting Off Route Data
There are two methods for collecting off route measurements with the Enpac Ex.
1. Choose one of the pre-defined measurements on the Off Route
Measurement screen. This method provides an easy way to collect off
route measurements for the current point.
Enpac Ex provides seven pre-defined measurements for you to use to
collect the off route data. You do not need to set any parameters if you
use the pre-defined measurements. The Enpac Ex uses the
measurement definitions for the current point. See Collecting Off Route
Data using a Pre-Defined Measurement on page 90.
2. Create a user-defined measurement point. This method allows you to set
up and collect any type of measurement. See Creating and Collecting a
User-Defined Point on page 92.
Collecting Off Route Data using a Pre-Defined Measurement
The Enpac Ex provides seven pre-defined measurements for you to use to
collect off route data. The pre-defined measurements are as follows:
• Same - uses the same setup as the current point
Publication GMSI00-UM001A-EN-E - February 2005
• Opposite - uses the opposite setup as the current point (e.g. spectrum is
time, time is spectrum)
Collecting and Reviewing Data 91
• Accel - acceleration spectrum point (10kHZ, 800 lines, 4 averages)
• Vel oc it y - accel - velocity spectrum point (2kHz, 400 lines, 4 averages)
• Accel Time - time point (10kHz, 2046 points)
• High Res - high resolution point (increase number of lines by a factor
of two, for example, the current point having 400 lines becomes 800
lines)
• gSE - spike energy point (Envelope parameter in Instrument Setup
must be set to "gSE." See Instrument Setup Parameters on page 105.
• ESP - standard Envelope Spectrum Processing (ESP) point (Envelope
parameter in Instrument Setup must be set to "ESP." See Instrument
Setup Parameters on page 105.
