The Enpac 2500 Data Collector Chapter 1
Using Memory Cards The Enpac 2500 can store program information and collected data on memory
cards. The Enpac 2500 is configured to accept any standard PCMCIA compact
flash (via adapter), Secure Digital (SD) memory card up to 2 GB that is
supported with a Microsoft Windows CE driver.
The Enpac 2500 data collector, version 3.10 and later supports the Secure Digital
High Capacity (SDHC) storage cards up to storage card up to 16 GB that is
supported with a Microsoft Windows CE driver.
PC cards may be inserted when the instrument is powered on or off. If any
memory card is not formatted to the correct standard, the instrument
automatically opens a dialog prompting you to format the card. We recommend
that memory cards be formatted Fat 16.
In this dialog, press either of the READ/OK buttons to format the card for use
with the Enpac 2500.
Trigger Sets the trigger source. External (default)
Uses the trigger input from the POWER/USB/TRIGGER connector as the
trigger source.
Laser Tach
Enables the internal Laser Tachometer when a Phase or Order
measurement is collected.
Trig Level Sets the trigger level. Applies only to triggered measurements (rpm points, phase points, time-synchronous averaged points).
Hist. Data Collect Determines how data is stored in the Enpac 2500 data collector when
collecting multiple measurements for a signal point:
• If you want to conserve space, you should select Always Overwrite.
• If you want multiple data sets to be stored and unloaded, select
Always Append.
Always Append: adds the new data for a point to existing data.
Always Overwrite: replaces existing data with new data.
Always Ask (default): displays a dialog box before attempting to store
the data.

Parameter Description Value
Value Description
Automatic Samples the trigger signal before collecting the triggered measurement and sets an appropriate trigger level
automatically. When collecting data on a triggered point, a message displays on the screen while the trigger level is being
sampled.
The length of time for which the trigger is sampled during autotriggering is dependent on two factors:
• The high pass filter selected for the point.
• The lower the high pass filter cutoff, the longer the trigger will be sampled.
Mach. Speed
If the Mach. Speed is set to Normal, the maximum trigger sampling time is about one second. If the Mach. Speed is set to
Slow, the maximum trigger sampling time is about 10 seconds. The Normal setting supports autotriggering on machines
running at speeds down to ~120 rpm. The Slow setting will support autotriggering on machines running at speeds down
to ~6 rpm, depending on the width of the trigger pulse.
Fixed: Default The Enpac 2500 data collector uses the signal level entered in the point setup information (either Route or Offroute) as the
trigger point.
IMPORTANT The Enpac 2500 data collector is only certified for use with the Sandisk
Secure Digital (SD) card SDSDx-yyy.
