4.

Record the device number or device name assigned to the DMM. You need this when programming 
the DMM.

(NI-DAQmx devices)

 The assigned device name is appended to the DMM in its configuration 

tree label. For example, after installing the NI PXI-4070, the device configuration tree label 
may appear as 

NI PXI-4070:

 

"

Dev1"

, where 

Dev1

 is the device name that MAX assigned 

to the DMM. When developing your application, the resource name for the DMM is this 
device name.

(Traditional NI-DAQ (Legacy) devices)

 Select the DMM to see its properties in the configuration 

view. The device number appears in the Values column. When developing your application, 
the resource name for the DMM is 

DAQ::

n

, where 

n

 is the device number MAX assigned to 

the DMM.

Note

To avoid modifying existing applications that use a Traditional NI-DAQ (Legacy) device 

number, change the assigned NI-DAQmx device name. To change an NI-DAQmx device name, 
right-click the DMM, select 

Rename

, and enter the Traditional NI-DAQ (Legacy) device number 

used in your application. For more information about device naming conventions, refer to the 

niDMM Initialize 

or 

niDMM_init 

topic in the 

NI Digital Multimeters Help

 located at 

Start»All 

Programs»National Instruments»NI-DMM»Documentation»NI Digital Multimeters Help

.

5.

Perform a self-test on the DMM to verify installation.

(NI-DAQmx devices) 

Right-click the DMM and select 

Self-Test

. If you need help during the 

self-test, open the 

Measurement & Automation Explorer Help for NI-DAQmx 

by selecting 

Help»Help Topics»NI-DAQmx»MAX Help for NI-DAQmx

.

(Traditional NI-DAQ (Legacy) devices)

 Right-click the DMM, select 

Properties

, and click 

Test 

Resources

.

A dialog box appears and indicates whether the DMM passed the test.

Note

If the DMM does not pass the test, repeat the steps in the 

5. Installing the Hardware

 section. 

If the DMM still does not pass the test, visit NI Technical Support at 

ni.com/support

.

6.

(NI-DAQmx NI 407

x

 devices only)

 Perform a self-calibration on the DMM. Right-click the DMM and 

select 

Self-Cal

. The DMM must warm up for at least 60 minutes before self-calibrating.

7.

Launch the DMM Soft Front Panel to run functional tests and to use the DMM. You can launch 
the DMM SFP from

Start»All Programs»National Instruments»NI-DMM»NI-DMM Soft 

Front Panel

Note

(NI 4050 and NI 4060 only)

 You can complete the following steps to run the functional test 

panels and to use the DMM. Right-click the NI 4050 and NI 4060 and click 

Test Panels

. Refer to the 

8. Connecting Signals

 section to connect a signal to the DMM. Click 

Close

 to close the test panels 

for the NI 4050 and NI 4060.
