This file contains important information about NI-DMM, including installation instructions, new features, a partial list of bugs fixed, and known issues.
If you plan to use LabVIEW NXG, refer to LabVIEW NXG Support and Considerations.
NI-DMM is an NI instrument driver that communicates with all NI programmable digital multimeters (DMMs). NI-DMM is an interchangeable virtual instrument (IVI)–compliant instrument driver, and it features a set of operations and properties that exercise the functionality of the DMM and includes an interactive soft front panel and examples.
NI-DMM 18.1 has the following requirements:
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW.
NI-DMM 18.1 supports the following operating systems:
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note In 2016 NI-DMM dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. NI-DMM 18.1 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-DMM 18.1 to an unsupported OS. Additionally, after installing NI-DMM 18.1, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.
For more information about the changes to our OS support for 2016, refer to KB 79UC78LS, Why Does My NI ADE Installer Fail on Windows XP/Vista and Windows Server 2003?.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit ni.com/info and enter the Info Code PAESupport.
NI-DMM 18.1 supports the following application software versions, including service packs. If you are not using NI application software, refer to Microsoft Visual Studio Support.
|Application Software||Versions Supported by NI-DMM|
|LabVIEW||2015, 2016, 2017, 2018|
|LabVIEW Real-Time Module||2015, 2016, 2017, 2018|
|LabVIEW NXG||2.0, 2.1|
|LabWindows™/CVI™||2013 and later|
|LabWindows/CVI Real-Time Module||2013 and later|
If you are using the NI-DMM .NET Class Library, the .NET Framework 4.0 (minimum) is required. The NI-DMM .NET Class Library can be used with the Visual C# or Visual Basic .NET programming languages in any Visual Studio version that can target the .NET Framework 4.0 or the .NET Framework 4.5.
To use the .NET API, you must select the .NET Framework 4.0 Languages Support or the .NET Framework 4.5 Languages Support packages in the NI-DMM installer to install the .NET class libraries in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to the National Instruments .NET Driver Support document at ni.com/info and enter Info Code NETAPIdriversupport.
You can install all of your LabVIEW products—including NI-DMM 18.1—using the LabVIEW 2018 Platform media.
To request additional LabVIEW Platform media, refer to the NI website.
NI automates LabVIEW NXG installation using NI Package Manager. Visit ni.com/info and enter the Info Code NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
The following list details the hardware models supported in NI-DMM 18.1.
PXI Amplifier Module

Digital Multimeter Device
You can access the software and documentation known issues list online. Refer to the NI website for an up-to-date list of known issues in NI-DMM 18.1.
The following items are the IDs and titles of a subset of issues fixed in NI-DMM. This is not an exhaustive list of issues fixed in the current version of NI-DMM. If you have a CAR ID, you can search this list to validate that the issue has been fixed.
The following items are changes in NI-DMM 18.1 from NI-DMM 18.0.
|575369||Fixed an issue affecting the PXIe‑4080, PXIe‑4081, and PXIe‑4082 that caused additional trigger latency in waveform mode.|
|682078||Fixed an issue affecting the PXI/PCI/PCIe/USB‑4065 when the Range property was set to Auto Range Once that caused the device to perform an autorange each time the Read or Initiate VIs were called rather than for only the first measurement of an acquisition.|
The following items are changes in NI-DMM 15.2 from NI-DMM 14.0.
|507445||Fixed an issue in NI-DMM 14.0 where the Capacitance, Susceptance, Resistance, and Reactance attributes had incorrect IDs and wrote to the incorrect attributes in the NI-DMM property node. The attributes have been fixed with the correct IDs and now write to the correct attribute. The Susceptance and Resistance attributes were incorrectly set as integer types, producing an IVI_ERROR_TYPES_DO_NOT_MATCH error. The attributes have been fixed to doubles.|

NI-DMM no longer installs IVI Compliance Package. NI-DMM supports IVI configuration and runtime, but no longer supports the following features:
If you want to use the above features, you must install IVI Compliance Package separately, either from ni.com/downloads or from the NI Device Drivers 2018 DVD.
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.
When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher.
