Defining a Sample

3.3 Defining a Sample

3.3.1 When Not Using a Sample Table

When “Use Sample Table” is not selected in Analysis Method setting, take the following procedure for defining a sample prior to measurement. (Refer to “3.3.2 When Using a Sample Table” when “6 Cell Mode On” and “6 cell control mode On” are selected on the General tab page with the U-5100 connected.)

(1) Click the button, and a window as shown in Fig. 3-10

will appear.

Fig. 3-10

(2) Enter a sample name and comment.

Maximum number of input characters (half-size)

Sample name : 40 characters Comment : 255 characters

For automatic saving of data, put a check mark at “Auto File” and specify a file name. Click Select button, specify a save location and enter the file name.

By putting a check mark at “Auto File” and check marks at “Auto JCAMP-DX file”, “Auto Text file” and “Auto Meta file”,

a time scan data file can be automatically saved together with files of the formats given below.

 JCAMP-DX Files (*.dx)  ASCII Text Files (*.txt)  Graph Meta Files (*.wmf)

Specified files will be saved under the file names at the save destination.

(3) When your setting is completed, click OK button.

3.3.2 When Using a Sample Table

When “Use Sample Table” is selected in Analysis Method setting, take the following procedure for defining a sample prior to measurement. (With the U-5100, a sample table is also usable on condition that “6 Cell Mode” and “6 cell control mode” are both activated on the General tab page. In this case, the maximum number of samples is limited to 5. The set number of samples will automatically be measured.)

Open the monitor window and click the (Edit Sample Table) button. The Sample Table dialog box will appear as shown in Fig. 3-11, so enter sample names and desired comments. Then, specify a destination folder for saving data, and set up a file name.

(1) To create a new sample table, enter the number of samples and click Update button. For instance, when there are five samples, enter “5” at Number of Samples and click Update.

When a sample table has already been created, a confirmation message stating “Changing the number of sample entries will clear all existing records. Are you sure you want to continue?” will appear. Clicking Yes will create a new sample table for the specified number of samples. Clicking No will halt the processing.

(2) To add a line to the end of the sample table, click the Insert button. A line will be added at each click of this button.

(3) To delete an unnecessary line in the table, click the No. of the line to be deleted to make it active as shown in Fig. 3-12. Then click the Delete button.

The activated line is thus deleted.

(4) It is possible to click the sample name and comment

columns for each sample and enter the necessary data directly.

Name : 40 characters

Comments : 255 characters

3.3 Defining a Sample

For the U-5100, the function for auto zero before sequence is provided. When the check box for this function is turned on, auto zero will be carried out with cell A before sample measurement. After the auto zero operation, sample measurement is carried out. Unless the check box is turned on, sample measurement starts without auto zero operation. Therefore, auto zero operation is always required before start of measurement.

U-5100

(5) Collective Input of Sample Names

It is possible to set sample names collectively, such as Common Sample Name + Start No., Common Sample Name + (Start No. + 1) …, in the following procedure.

(a) Enter a common name for the samples at Common Sample Name. A maximum of 36 half-size characters can be entered. (Example: SampleB)

(b) Put a check mark at Auto Numbering and enter a Start

No. (Example: Start No. = 1)

(c) Click the No. column of the sample table and select the top line for collective input of sample names. While holding down the Ctrl key, click the No. part of the sample name to be set and select several lines.

(d) Now click Input key, and the Common Sample Name + Start No., Common Sample Name + (Start No. + 1)… will be set. (“SampleA001 to SampleA005” are set for the sample name in Fig. 3-16.) By pressing the Input key without putting a check at Auto Numbering, setting will be made at the lines on which the sample common name has been activated.

(6) Specify a save destination folder for the data files, in the

following procedure.

(a) When a save destination folder has been created, display a folder reference dialog by means of the Browse button. After folder selection, click the OK button on the Browse for Folder dialog shown in Fig. 3-18.

(b) Take the following procedure for newly creating a

folder.

1) Click the Browse button to display a folder reference dialog as in Fig. 3-18. Specify a path for creating a folder.

2) Click the Create Folder button and a Create New Folder dialog as shown in Fig. 3-19 will appear. Enter a folder name in the Name column and click OK button. A folder having the name specified under Current folder will thus be created.

Fig. 3-19 Create New Folder Dialog

(7) Enter a file name. (Example: test1) The data file name will be saved in the destination folder as “File name – sample No.” (Example: test1-001.udt) If the same file name already exists, the file will be saved as “Data file name + measurement date/time”. (Example: test1-001_20100811164856.udt)

(8) When the necessary information has been entered for the sample table, check it and then click OK button.

(9) Cancel Button

Clicking this button will prevent the entered information from being reflected on the process.

(10) Load Table Button

This is used for loading an existing sample table. Clicking this button will display a dialog for opening a file.

Fig. 3-20 Dialog for Opening a File

Upon selecting a sample table and clicking Open button, the specified sample table will be loaded.

(11) Save Button

Clicking this button will overwrite and save the altered contents. When a table has been newly created, the Save As dialog will appear.

(12) Save As Button

This is used for saving a file under a new name. Clicking this button will open the Save As dialog.
