Obsolete VIs/Functions

The following VIs/functions are obsolete, and no maintenance is provided for these VIs/functions:

Known Issues

• If you click a topic link in the NI-DMM C Reference Help section of the NI Digital Multimeters Help, you cannot use the Back button in the HTML Help window toolbar to return to the original topic.
• The NI PCI/PCIe-4065 may produce undesired triggers on the Voltmeter Complete signal when configured for Auto Range measurements. To avoid undesired performance, do not trigger while configured for an Auto Range acquisition.
• NI recommends that you disable Windows power management modes, such as sleep, standby, and hibernate, when using this product. These modes terminate any NI-DMM operation in progress. Notice that in Windows Vista or on a laptop computer, the default power management settings are likely to enable sleep mode.
• When you run setup.exe to install the software from the CD, you are prompted to choose whether you want to always trust software from National Instruments. If you do not select this option, your installation may be interrupted by one or more Microsoft Windows security dialog boxes. However, if you run setup from the command line, you will not receive this prompt, and the installer will automatically install NI's Software Publisher Certificate to the your Windows Trusted Publisher Store. If you do not want to make this change to your Windows Trusted Publisher Store, do not choose this installation method.
• The NI PXI-4070 can not operate as a Traditional DAQ (Legacy) SCXI controller in Windows Vista.
• The NI PXI-4070 was upgraded and new revisions of the device beginning with 191485A-01 are incompatible with versions of NI-DMM prior to 2.3. NI-DMM 2.3 and later provides support for all revisions of the NI PXI-4070.
• The IVI Configuration Store file format now requires that all names be case-sensitive. If you use logical names, driver session names, or virtual names in your program, make sure that the name you use matches the name defined in the IVI Configuration Store file exactly, without any variations in the case of the characters in the name.
• The NI 4065/4070/4071/4072 can be programmed only with NI-DMM. NI-DAQ function calls and DAQ virtual channels are not supported by the NI 4065/4070/4071/4072. Using NI-DAQ with the NI 4065/4070/4071/4072 can cause an error that requires a system reboot.
• In MAX under the Configuring Device window for the NI 4065/4070/4071/4072, Run Test Panels is grayed out.
• In MAX under the Configuring Device window for the NI 4065/4070/4071/4072, Test Resources always indicates that the device has passed the test regardless of the condition of the device.
• If you are replacing the NI 4060 with the NI 4065 or NI 4070/4071/4072 in an application that uses triggering, consider the following differences in behavior:
  • The NI 4060 configured as an SCXI controller automatically sets the Measurement Complete (MC) destination to the location where SCXI is configured (external or internal PXI/SCXI trigger lines).
  • The NI 4065 and NI 4070/4071/4072 configured as an SCXI controller automatically sets the MC destination to NONE.
  
  
  If your application relies on the routing behavior of the NI 4060 by not explicitly calling niDMM Configure Measurement Complete Destination, you must modify your application by calling the VI/function. Alternately, the NI 4065 and NI 4070/4071/4072 can emulate NI 4060 routing behavior by specifying the following registry key:
  
  HKEY_LOCAL_MACHINE\Software\National Instruments\NI-DMM\CurrentVersion\legacyMCRoute
  
  where the value is a DWORD set to 1.
  
  

  Note: For Windows Vista x64, specify the following registry key:
  
  HKEY_LOCAL_MACHINE\Software\Wow6432Node\National Instruments\NI-DMM\CurrentVersion\legacyMCRoute

  Without this registry key, NI-DMM sets NIDMM_ATTR_MEAS_COMPLETE_DEST to NONE for the NI 4065 and NI 4070/4071/4072. With this registry key, NI-DMM sets NIDMM_ATTR_MEAS_COMPLETE_DEST to the location where SCXI communication is configured in the application.
• There are known DLL collision issues with the Visual Basic debugger and National Instruments device drivers. A support DLL used by NI-DMM fails to load if Visual Basic has already loaded another DLL into the same address space. More information on this issue and solution are documented in KnowledgeBase entry 2Q1HG8A6. Refer to ni.com/support to access the KnowledgeBase.

Changes by Release

Changes in NI-DMM 2.7.2 from NI-DMM 2.7.1

• Support for LabVIEW 8.5.

Changes in NI-DMM 2.7.1 from NI-DMM 2.7

• Support for the NI PXI-4065.
• New behavior: For NI 4065 and NI 407x devices, NI-DMM 2.7 incorrectly swapped the Settling Time behavior of triggered and non-triggered multipoint measurements. This behavior resulted in overly-short Settling Times in triggering/switching applications, which could affect measurement quality, and overly-long Settling Times in non-triggered applications. This behavior has been corrected in NI-DMM 2.7.1.

Changes in NI-DMM 2.7 from NI-DMM 2.6

• Support for Windows Vista.
• Datalogger support in NI LabVIEW SignalExpress 2.0 and later.

Changes in NI-DMM 2.6 from NI-DMM 2.5

• Support for the NI PCI/PCIe-4065.
• Introduction of the niDMM Cal Adjust Linearization VI and the niDMM_CalAdjustLinearization function.
• A change was made in NI-DMM 2.6 to ensure that NI 407x devices operate as expected in industrial PC chassis and across MXI configurations (including MXI Express).
• A change was made in NI-DMM 2.6 to ensure that the NI 407x front-end is fully configured before returning from niDMM Initiate or niDMM Control (when the Control Action parameter is set to "Commit").
• On versions of NI-DMM prior to 2.6, NI 4060 users may encounter a rare intermittent behavior that results in a hang or crash. This behavior is typically encountered upon initializing the device a second time within the same instance of an application environment such as LabVIEW. This behavior may also be seen during a calibration routine within Calibration Executive and has been corrected as of NI-DMM version 2.6.

Changes in NI-DMM 2.5 from NI-DMM 2.4

• Introduction of the DMM/Switch Express VI.
• Introduction of the niDMM Control VI and the niDMM_Control function.
• Support for LabVIEW 8.0.
• Support for LabVIEW Real-Time Module 8.0 (NI PXI/PCI-4070, NI PXI-4071, and NI PXI-4072 only)
• New behavior: Initializing a session with the niDMM Initialize VI or the niDMM_init function now closes any other existing sessions open to the same device in the same process. Calling the niDMM Initialize VI or the niDMM_init function therefore always results in the creation of a new session rather than returning an existing session.

Changes in NI-DMM 2.4 from NI-DMM 2.3

• Support for the NI PXI-4071.
• Introduction of the NI-DMM Express VI.
• Support for NI SignalExpress 1.1.
• Introduction of the niDMM Config Measurement VI and the niDMM_ConfigureMeasurementDigits and niDMM_ConfigureMeasurementAbsolute functions.

Changes in NI-DMM 2.3 from NI-DMM 2.2

• Support for the NI PXI-4072.
• Support for the LabVIEW Real-Time Module has been added. For more information about using NI-DMM with the LabVIEW Real-Time Module, launch the NI Digital Multimeters Help and select Programming with NI-DMM»Getting Started»Using NI-DMM in LabVIEW»Considerations for Using the LabVIEW Real-Time Module.
• Inclusion of Measurement Studio C++ interface to NI-DMM.

Changes in NI-DMM 2.2 from NI-DMM 2.1

• Support for the NI PCI-4070.
• Support for the NI PXI/PCI-4070 devices to control an SCXI chassis that contains NI-DAQmx SCXI modules has been added (NI PXI/PCI-4070 only).
• Support in MAX for the Self-Test and Self-Calibrate buttons for NI-DAQmx devices has been added (NI PXI/PCI-4070 only).
• Support for the "break-on-library-error" feature in LabWindows/CVI (CVI user protection).
• NI-DMM removes Offset Compensation Ohms capability for ranges 100 kΩ and greater.
• NI-DMM corrects the resistance reference adjustment function of the external calibration procedure.
• The IVI Configuration Store file format now requires that all names be case-sensitive. If you use logical names, driver session names, or virtual names in your program, make sure that the name you use matches the name defined in the IVI Configuration Store file exactly, without any variations in the case of the characters in the name.

Changes in NI-DMM 2.1 from NI-DMM 2.0

• Self-test and simulation have been added for the NI PXI-4070.
• The 1 MΩ input resistance value is no longer valid for DC voltage measurements on the NI PXI-4070.
• AC voltage measurements using the DC coupling on the NI PXI-4070 have been improved to account for a computational error.
• A new error code, NIDMM_ERROR_INVALID_MEAS_COMP_DEST has been created. This error is returned if an Input Trigger or Sample Trigger source is set to the same value as the Measurement Complete (MC) destination.
• The self-calibration algorithm for the NI PXI-4070 has been updated to improve the gain correction.
• Resistance measurements have been improved for low resolutions that enable both ADC calibration and offset compensated ohms.
