DataLoggerXP User’s Manual • Page 1
Introduction
Thank you for buying DataLoggerXP! With Datalogger XP you can record up to six thousand
measurements, on an intrinsically safe, fully temperature compensated pressure gauge. With the
XP2i’s long battery life you can take measurements for up to three months, without the need for
external power supplies or battery replacements.
With an XP2i and DataLoggerXP you can:
Record up to 6000 pressure measurements (data points)
•
Change data collection parameters, with or without a computer
•
Start and stop multiple collection runs from the keypad
•
Record pressure readings at intervals as quick as once per second or as slow as once
•
every 18 hours.
Record the averages, averages and peaks, or just the pressure indication.
•
Store an indicated pressure by pushing one button.
•
View the data on any Windows-equipped computer.
•
Save the data les directly into Microsoft® Excel spreadsheets (Excel 95 through Excel 2003), or
•
as comma separated text les.
How it works
There are two parts of this solution—the DataLoggerXP program and the XP2i Digital Test
Gauge. Both are required to form a data logging solution. The Windows application handles all
the transfer and saving of data from the gauge to your computer’s hard drive, while the XP2i performs all the actual data collection.
XP2i Operational Modes
A data logger XP2i operates dierently than a standard XP2i. When operating as a data logger, the
software internal to the XP2i, called the rmware, is replaced. The rmware within the XP2i denes
the mode of the gauge.
When the gauge is operating in standard mode, the XP2i provides all of the functionality documented in the XP2i’s Operation Manual. This is the mode in which all gauges are shipped from the factory.
The DataLoggerXP program switches a gauge into data logger mode. Mode changes take less
than a minute, and can be done an unlimited number of times. Datalogger mode adds the capability to record pressure readings. The accuracy of the gauge is unaected by this change, but
some capabilities (such as peak display and multiple pressure scales) are removed to allow for
maximum memory availability. For information on the changes in gauge operation while operating in data logger mode, see “Dierences Between the XP2i Datalogger and XP2i “ on page 12.

Note: An evaluation mode allows up to 100 data points to be taken after which authorization
is required. For unlimited operation, the gauge must be authorized for use as a data logger.
The gauge can be authorized either by the factory, prior to shipment, or in the eld, by the
use of an authorization key. Gauges are always shipped from the factory in standard mode.
Datalogger Terminology
The XP2i stores data in memory. Memory is expressed in terms of bytes available, with each data
point taking some number of bytes to store. A clear gauge (one without any data in memory) will
have approximately 8,000 bytes available. How long a gauge can log data depends on several factors, each of which is described below.
The rst factor is the logging interval. This is the time, in seconds, between each data point.
The second factor is the logging type. The logging type controls what kind of data is stored for
each reading, with dierent modes requiring dierent amounts of memory for each reading.
The third factor is the dynamics of the input pressure. Data is compressed into memory whenever possible. Therefore, pressure that is changing slowly over time will require less memory as
compared to large variations of input pressure. More information on how these factors aect the
maximum number of readings can be found under “Maximum Number of Readings” on page 9.
Together, the logging interval and logging type are referred to in this document as the logging
parameters. Logging parameters can be set up one of two ways: on a computer connected to an
XP2i, or on an XP2i by itself. This second option allows the user to make changes in the logging
parameters while in the eld.
Once the logging parameters have been selected, the gauge can begin sampling data. A set of
one or more readings taken by the gauge is called a run. The user can specify dierent logging parameters for each successive run. There is no limit to the number of runs a gauge can store, providing there is sucient memory to store them.
After one or more runs have been stored on the gauge, DataLoggerXP can download the data to a
computer for viewing and/or saving to the computer’s hard drive. This is done by simply connecting the gauge to the computer via a serial cable and using the Download function of the application software.
Once the data is downloaded to the computer, you will typically clear the gauge. This removes
any existing runs from the gauge’s memory, so that all of the memory is available for the next
sequence of runs.
Typical Usage
While there are a variety of ways in which the DataLogger software and XP2i digital test gauge can
be used, a typical way to use the Datalogger might be like this:
1 You set up the logging parameters—either on the computer or directly on the XP2i keypad—
and start recording data.

2 Once the logging is complete, the test gauge is connected to a computer.
3 Using the DataLoggerXP application, you download one or more runs to the computer.
4 You save one or more of the runs to Excel worksheets, or as text les.
Installing the Software
DataLoggerXP can either be installed from a CD provided by Crystal Engineering, or downloaded
from the Crystal Engineering web site; however, it’s recommended to check the Crystal Engineering (www.xp2i.com) web site for the latest version of the software.
To install from the CD, simply run the Setup.exe application located on the install CD. This is typically D:\Setup.exe, but may be dierent on your computer.
To install from the Internet, visit http://www.crystalengineering.net and select the DataLoggerXP software page to download the latest version of the software.
Once the setup application is started, simply follow the on-screen prompts to complete the installation.
If DataloggerXP is being upgraded, the prior version does not need to be uninstalled. The new version will be installed over any existing version.
Quick Start
For experienced users, the following quick-start should provide sucient information to get up
and running quickly:
XP2i Initial Setup
Because the gauge is not shipped in Datalogger mode, rst time setup requires the use of a computer. Once the XP2i has been congured as a datalogger, settings can be changed from either
the DataloggerXP application, or from the XP2i’s keypad.
1 Connect the gauge to the computer with a serial cable, P/N 2400 or equivalent.
2 By default, DataloggerXP is congured for automatic serial port detection. If you need to set a
specic port, select View > Options from the main menu.
Page 4 • DataLoggerXP User’s Manual
3 Then select the Serial port from the drop down list and click OK.
4 Click the Connect button to connect to the gauge.
5 If the gauge is not in datalogger mode (as shipped from the factory) you will see this message:
Press the Switch Mode button to convert it to datalogger mode, then press Yes.
