Other Equipment
There are several required items not included in your device kit that you need to
install or operate the NI 4080/4081/4082.
■1/8 in. flathead screwdriver
■A PXI Express chassis with a controller and the chassis documentation
Installing the Soware
You must be an Administrator to install NI soware on your computer.
1. Install an ADE, such as LabVIEW or LabWindows™/CVI™.
2. Download the driver soware installer from ni.com/downloads.
NI Package Manager downloads with the driver soware to handle the
installation. Refer to the NI Package Manager Manual for more information
about installing, removing, and upgrading NI soware using NI Package
Manager.
3. Follow the instructions in the installation prompts.
Note Windows users may see access and security messages during
installation. Accept the prompts to complete the installation.
4. When the installer completes, select Restart in the dialog box that prompts
you to restart, shut down, or restart later.
Installing the NI 4080/4081/4082
Notice To prevent damage to the NI 4080/4081/4082 caused by ESD or
contamination, handle the module using the edges or the metal bracket.
1. Ensure the AC power source is connected to the chassis before installing the
module.
The AC power cord grounds the chassis and protects it from electrical damage
while you install the module.
2. Power o the chassis.

9. Latch the module in place by pulling up on the ejector handle.
10. Secure the module front panel to the chassis using the front-panel mounting
screws.
Note Tightening the top and bottom mounting screws increases
mechanical stability and also electrically connects the front panel to
the chassis, which can improve the signal quality and
electromagnetic performance.
11. Cover all empty slots using either filler panels (standard or EMC) or slot
blockers with filler panels, depending on your application.
Note For more information about installing slot blockers and filler
panels, go to ni.com/r/pxiblocker.
12. Power on the chassis.
Hardware Front Panel Connectors

Requirements for Cables and Probes
The DMM shipping kit contains a pair of test probes with safety banana plugs. These
probes meet international safety requirements, including UL 3111 and IEC-1010-1,
for the full range of applications supported by the DMM.
Caution Before using any probes or accessories, ensure that they meet
applicable safety requirements for the signal levels you may encounter.
Connect the test probes to the banana plug connectors on the DMM front panel
using safety banana plugs. The shrouds around the banana plugs prevent you from
contacting potentially hazardous voltages connected to the test probes. You can
also connect the cable to standard, unshrouded banana plug probes or accessories.
Use unshrouded probes or accessories only when the voltages are less than 30 Vrms
and 42 Vpk, or 60 VDC.
Caution (NI 4081 users) To prevent possible safety hazards, the
maximum voltage between any of the inputs and the ground of the PXI
Express chassis is 500 VDC or 500 Vrms (sine wave), except between the HI
terminal and ground, where the maximum voltage is 1,000 VDC
or700 Vrms (sine wave). The maximum current the NI 4081 can measure
through the current inputs is ±3 ADC or 3 Arms.

PXIe-4080/4081/4082 Getting Started

Caution (NI 4080/4082 users) To prevent possible safety hazards, the
maximum voltage between any of the inputs and the ground of the
computer is 300 VDC or 300 Vrms. The maximum current the NI 4080/4082
can measure through the current inputs is ±1 ADC or 1 Arms.
Configuring the NI 4080/4081/4082 in MAX
Use Measurement & Automation Explorer (MAX) to configure your NI hardware. MAX
informs other programs about which NI hardware products are in the system and
how they are configured. MAX is automatically installed with NI-DMM.
1. Launch MAX.
2. In the configuration tree, expand Devices and Interfaces to see the list of
installed NI hardware.
Installed modules appear under the name of their associated chassis.
3. Expand your Chassis tree item.
MAX lists all modules installed in the chassis. Your default names may vary.
Note If you do not see your module listed, press <F5> to refresh the
list of installed modules. If the module is still not listed, power o the
system, ensure the module is correctly installed, and restart.
4. Record the identifier MAX assigns to the hardware. Use this identifier when
programming the NI 4080/4081/4082.
5. Self-test the hardware by selecting the item in the configuration tree and
clicking Self-Test in the MAX toolbar.
The MAX self-test performs a basic verification of hardware resources.
Programming the NI 4080/4081/4082
You can acquire data interactively using the NI-DMM So Front Panel (SFP), or you
can use the NI-DMM instrument driver to program your device in the supported ADE
of your choice.
