Description
The Enpac 2500 can now save the cursor frequency value as speed. The 1XRPM that appears during data collection can be used to
set the machine speed based on cursor position. The cursor value is stored in the Machine Speed column of the Data History screen
in the Emonitor software.
The Enpac 2500 data collector, revision 3.0 will display a warning message when moving between measurement points that are
configured for different sensors (like moving between acceleration and velocity measurements).
This function can be activated or deactivated through the Transducer Change parameter in the Setup utility screen.
Do not Warn = No message is displayed
Warn = Message is displayed when transducer is different than previous point
This function was implemented to meet the requirements of most Nuclear facilities where the sensitivity used by the Enpac 2500
must be typed in exactly as marked on the sensor. This function gives the ability to change the sensitivity of sensors for route
based measurements.
IMPORTANT: If your facility does not require this function, then it is not recommended that it be used. Incorrect settings can affect
measurement results.
The Enpac 2500 data collector, revision 3.0, supports printing screen shots to the SD memory card.
The Enpac 2500 data collector, revision 3.0, gives two options to check the bias voltage before data collection. To configure Bias
Checking, select the desired setting in the Setup Utility.
Manual: To manually check the bias voltage by pressing the 0+2 keys simultaneously while in the data collection screen.
Automatic: Will automatically check and display the bias voltage for every point prior to data collection.
This revision of the Enpac 2500 data collector has the ability to determine the speed using a frequency reference item in Emonitor
software. This allows for machine speeds to be stored and retrieved dynamically.
The speed reference can be configured as a manual entry or a tachometer (external or internal) and its value is used by the
frequency items to calculate the Fmax of the dependent measurements. The speed reference frequency is set up in the Frequency
Item pane in Emonitor.
Refer to the Enpac 2500 User Manual, publication GMSI10-UM002, for more information.
The SD memory card has been added as an option to the Route Memory parameter in the Instrument Setup. You can use the SD
card to load and unload lists from Emonitor software.
The Enpac 2500 data collector supports up to 4 GB in size and 60X speed. The unit also supports a PCMCIA to SD converter.
The Enpac 2500 data collector can now collect multiple readings for a single measurement point. The data collector can store up
to 10 additional measurements for the same measurement point. These additional measurements can be uploaded to your
database if so desired.
When you collect more than one spectrum for a point, the unit can display the spectrum in a waterfall plot. This enables you to
view several measurements in relationship to each other.
To support the multiple collection features, two new parameters have been added to the Instrument Setup – Hist. Data Collect
and Hist. Data Review. These parameters allow you to set up how the additional data will be stored and reviewed in the data
collector.
You can now use a special cursor to identify frequency items on a spectrum in the Enpac 2500. The frequency labels are
downloaded from Emonitor with your route. These diagnostic frequencies are the output items from the Frequency Items pane in
Emonitor.
Two additional averaging options are now supported – peak-hold and exponential averaging. You can use these averaging
options in your route and off route measurements.
The Enpac now supports the specification and collection of a spectrum with an Fmax defined in terms of number of orders for a
varying machine speed.
The Enpac can now remember the last collection point taken prior to turning off the collector or exiting a route.
The Review Data function is now available in the Data Collection screen. This allows you to review collected data within the route.
before you start collecting data.
