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：

System RequirementsMinimum System Requirements

• Processor: Pentium 200 MHz or equivalent

• RAM: 64 MB
  

Recommended System

• NI-DAQ version 6.9.3 or higher.

• NI-VISA or NI-VISA Run-Time Engine version 2.6.0 or higher.

• IVI Engine 1.83 or higher.

Installed File Names and Locations

• Select National Instruments Software from the list provided and click Change or Remove.

• Select NI-DMM 2.1 from the list provided and choose the appropriate action.
  
  

New Examples

• Self-test and simulation have been added for the NI 4070.

• The 1 MΩ input resistance value is no longer valid for DC voltage measurements on the NI 4070.

• AC voltage measurements using the DC coupling on the NI 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 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.
  

• The NI PCI-4060 supports Sample Trigger set to Software.

• Interaction problems with TestStand have been resolved.

• The DMM-SFP (soft front panel) supports device numbers greater than 15.

• Application examples were removed from the NI-DMM palette and are located at <LabVIEW>instr.libNIDMM idmm_apps.llb.

• Trigger Delay parameter can be set to Auto Delay OFF (-2).

• Range parameter can be set to AutoRange OFF (-2).
  

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

• In Measurement & Automation Explorer (MAX) under the Configuring Device window for the NI 4070, Run Test Panels is grayed out.

• In MAX under the Configuring Device window for the NI 4070, 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 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 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. 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 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.
