视觉论坛的各种资源，除了视觉相关的模块有使用外，大部分的都不会使用，所以仅提供资源不能提供技术支持。资源的下载地址一般会同时提供NI官方地址和百度网盘的下载地址。某些工具包NI的地址失效或没有NI的下载地址，那视觉论坛也没有办法，只能尝试使用百度网盘地址下载；如果百度网盘的下载地址失效过期，可联系论坛客服更新。现在NI的下载服务器对我国IP地址不是很友好，有些时候速度很慢或大的资源下载很容易出错，这样会造成安装过程各种类型报错而无法安装。建议在下载完成后，对下载资源做校验和验证（NI一般会提供MD5或SHA256等），与官方或视觉论坛提供的校验和对比，一致就可以安装，如果不一致，则需要重新下载。视觉论坛早期下载的资源，那时候NI没有这么多限制，基本上都是正常下载的资源；后期下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘，所以百度网盘的资源基本上是正确的。校验和工具下载地址：

Examples

Obsolete VIs/Functions

Known Issues

• The default aperture times listed in the NI Digital Multimeters Help are incorrect for the NI PXI-4071 on the 100 V DC range.燭he correct values are 1.6 millisecond for 5½ digits and 50 microseconds for 4½ digits.

• The recommended aperture times listed in the Maximizing DC Reading Rate examples are incorrect for the NI PXI-4071 on the 100 V DC range for 4½ and 5½ digits.

• Upgrading from NI-DMM 1.5 to NI-DMM 2.3 on a Windows NT 4.0 system can result in one or more error messages. To completely install NI-DMM 2.3 on such a system, you must acknowledge these error messages by clicking the OK dialog boxes.

• 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 4070/4071/4072 can be programmed only with NI-DMM. NI-DAQ function calls and DAQ virtual channels are not supported by the NI 4070/4071/4072. Using NI-DAQ with the NI 4070/4071/4072 can cause an error that requires a system reboot.

• In MAX under the Configuring Device window for the NI 4070/4071/4072, Run Test Panels is grayed out.

• In MAX under the Configuring Device window for the NI 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 PXI-4060 with the NI PXI-4070/4071/4072 in an application that uses triggering, consider the following differences in behavior:
  
  
  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 4070/4071/4072 can emulate NI 4060 routing behavior by specifying the following registry key:
  
  HKEY_LOCAL_MACHINESoftwareNational InstrumentsNI-DMMCurrentVersionlegacyMCRoute
  
  where the value is a DWORD set to 1.
  
  Without this registry key, NI-DMM sets NIDMM_ATTR_MEAS_COMPLETE_DEST to NONE for the 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.

• 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 4070/4071/4072 configured as an SCXI controller automatically sets the MC destination to NONE.
  

• 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 ReleaseChanges since NI-DMM 2.3

• Support for the NI PXI-4071 has been added.

• 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 has been added.

• 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 has been added.

• 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.
