DataLogger XP User’s Manual • Page 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.
Page • DataLogger XP User’s Manual 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 field, 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.
DataLogger XP User’s Manual • Page 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 files. 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.
Page • DataLogger XP 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.
DataLogger XP User’s Manual • Page Don’t disconnect or turn off the gauge while it’s being updated. 6 After the gauge has been updated, press the Connect button again. Then set the logging parameters: The Logging Type, and the Logging Interval (if it applies). Click Send to Gauge to update the gauge parameters. 7 When finished, click Disconnect. Recording Pressure 1 Connect the gauge to the pressure line to be monitored and turn it on.
Page • DataLogger XP User’s Manual Downloading 1 Reconnect the gauge to the serial cable and run DataloggerXP. 2 Click the Connect button to connect to the gauge. 3 Click Download to retrieve the data from the gauge. 4 Click View or Save to view or save the data, respectively. Operation Detailed operating instructions on the operation of the software and gauge can be found below.
DataLogger XP User’s Manual • Page The DataLoggerXP main window provides most of the functions of the application. From this window, connecting to a gauge, changing data collection parameters, downloading and viewing data, clearing data and switching operating modes can all be performed. The paragraphs below offer additional information on each of these features. Setting the Options By default, DataLoggerXP is configured for automatic serial port detection.
Page • DataLogger XP User’s Manual Changing Modes Changing modes on the XP2i is accomplished by clicking the Switch Mode button. The software will then proceed to make the appropriate mode change. When converting to data logger mode, the gauge must be upgraded to operate as a data logger. The software will automatically detect whether or not the gauge is authorized.
DataLogger XP User’s Manual • Page Data Logging Parameters The two parameters that affect data logging (logging interval and logging type) are covered below. LOGGING INTERVAL The logging interval controls how frequently the gauge takes a measurement. A logging interval can be as short as one second or as long as eighteen hours. LOGGING TYPE There are four logging types in which the gauge is capable of operating: • Actual: The gauge stores the value displayed on the gauge at each logging interval.
Page 10 • DataLogger XP User’s Manual Each logging type has a different storage requirement. The chart below provides the memory consumed per data point for each logging type: Logging Type Actual or Average Average with Peaks On Demand Bytes per Data Point 3 9 7 The third factor, the pressure dynamic, can significantly impact the maximum number of readings recorded. The gauge employs a data compression mechanism to store a greater number of data points.
DataLogger XP User’s Manual • Page 11 Saving Saving data can be accomplished from two places: clicking the Save button either directly from the main window or from the View dialog box. In either case, the application will first ask for the name of the file to save, and then which run data to save. A file can be saved as either an Excel workbook or comma separated text file (”.txt” or “.csv”) format. To save a file in Excel format, select either an Excel template file (ending in “.
Page 12 • DataLogger XP User’s Manual XP2i DataLogger Gauge Operation When in data logging mode, XP2i provides data logging capability along with the many of the features of a standard XP2i. In order to allow operation as a data logger, some of the functionality of the standard XP2i has been removed. However, using DataLoggerXP, it is possible to switch the XP2i ‘s mode as needed.
DataLogger XP User’s Manual • Page 13 The PEAK key will cycle through the types, where “Lt 1” is Actual, “Lt 2” is Average, “Lt 3” is Average with peaks, and “Lt 4” is on demand. The UNITS key accepts the format and the display advances to the logging interval, displayed in seconds. The PEAK key decrements and the ZERO key increments the logging interval. The UNITS key accepts the logging interval and the display reverts to normal.
Page 14 • DataLogger XP User’s Manual PEAK: When in data format 4, a reading is stored each time the PEAK key is pressed. When in this mode there is no need to press and hold UNITS to begin logging, although it is permissible to do so. If the unit has not already entered data logging type, “Start” is briefly displayed. The PEAK key has no function except as described above.
DataLogger XP User’s Manual • Page 15 the gauge’s clock with the computer’s clock which will allow the time stamps to be correctly read. However, if multiple resets have occurred with the gauge, only time stamps after the last reset will be fixed. When a reset occurs, it is stored as a run with a reset event and no data. Excel Templates In order to provide for a flexible reporting solution, DataLoggerXP is capable of directly interfacing with Microsoft® Excel to paste run data for reporting and graphing.
Page 16 • DataLogger XP User’s Manual Data Data is copied to the location specified in the Options Dialog. The user must provide the sheet, row, and column reference. If the reference is invalid, the data will be copied to the default active cell when the template is opened (usually column A of row 1 in the first worksheet in the Excel workbook). When the data is copied, it will overwrite any existing cell contents, but cell formatting will not be modified.
