[. . . ] Operation and Maintenance Manual GFS2102TM Gravimetric Flow Standard © 2007 DH Instruments, a Fluke Company GFS2102TM OPERATION AND MAINTENANCE MANUAL Pressurized gases are potentially hazardous. Energy stored in these gases can be released unexpectedly and with extreme force. Pressurized systems should be assembled and operated only by personnel who have been instructed in proper safety practices. © 2007 DH Instruments, a Fluke Company All rights reserved.

[. . . ] This option is provided to help avoid logging erroneous or inconsistent data caused by an incorrect K factor. Check this option to force GFS Tools to change the unit of measure and gas information of a DUT molbox to the settings required by the GFS during test initialization. Page 83 © 2007 DH Instruments, a Fluke Company GFS2102TM OPERATION AND MAINTENANCE MANUAL FEATURE Disable entry of K factors for non DHI products (check box) DESCRIPTION Un-check (recommended) this option to automatically populate the K factor field of a non DHI product (such as an MFC) with the K factor information stored in the Process Gas Editor. If the manufacturer gas information is not sotred in the Process Gas Editor, the K factor field is enabled for user entry. Use the [Tools][Process Gas Editor] menu choice to update gas information for a specific manufacturer. 5. 2. 2. 3 [END TEST] TAB The [Tools], [Options], [End Test] tab is used to set user preferences affecting operations that occur to conclude a test sequence. The purpose of the [End Test] tab fields and settings as well as instructions on how to use them are provided in Table 28. When selections are complete, click [OK] to save changes or select another tab to change other options. Selecting a fixed repeat point delay, deactivating the test notes and enabling the auto report generation can allow an automated test to run and generate a complete report without user intervention. Figure 54. Options, [End Test] Tab © 2007 DH Instruments, a Fluke Company Page 84 5. Options, [End Test] Tab Fields FEATURE Final point of each cycle (radio button selection) DESCRIPTION GFS Tools provides the capability to repeat test points using the Run Toolbar, [Back] icon. However, if a test ends automatically after the last point, there is no opportunity to repeat points when the last point has completed. This option determines whether a pause to allow points to be repeated after the last point is complete or automatically end the test without pause. There are three choices: Enable repeat for fixed time delay After the last test point is complete, the test pauses for a fixed time delay. During the delay, the Run Toolbar, [Back] icon remains active allowing points to be repeated. This choice gives the possibility of repeating points after the last point is complete but also causes the test to eventually continue automatically without operator intervention. Prompt to repeat Systematically pauses the test at the end of each test cycle and prompts the user to indicate whether the last test point should be repeated. This selection guarantees that the operator will consider whether to repeat points but it also prevents the test from completing automatically. There is no opportunity to repeat points after the last point is complete. Use this choice to prevent any delays or interruptions in the test sequence. No repeat option Auto generate report after complete tests (check box) Prompt for test notes at the end of the test (check box) Check this option to automatically create a report when a test completes. The <Test Complete> options still display at the end of the test. If checked, GFS Tools always prompts for test notes to be entered at the end of the test. The prompt occurs after all test data is collected and the flow is set to 0. In this case, no test notes can be included in the test's Data File. 5. 2. 2. 4 [DATA FILE] TAB The [Tools], [Options], [Data File] tab is used to set user preferences affecting the Data File (*. dat) which records the data from a test. [. . . ] The best fit flow as determined by calculating a real time best fit at the defined sample rate since the beginning of an accumulation, with the fit forced through zero. Automated mass handler; specialized platform for vertical actuation of the reference gas cylinder and reference mass on and off the balance mass tray, especially for AutoZero function. Device under test; the item being tested or calibrated by GFS, often a molbloc. The full scale value is the maximum value or the span of a measurement range. [. . . ]
