Overview
This VI is the NI ELVISmx Instrument Launcher’s Digital Multimeter (DMM) for the Mac OS. The DMM is an all-in-one instrument used to measure DC and AC voltage, DC and AC current, resistance, diode voltage, and continuity. This instrument has been adapted from its Windows OS form to work with a Mac OS, and the changes between these versions are explained below.

Hardware Instructions
This VI interfaces with the myDAQ using the DMM cables. Connect your device via USB and select that from the device list in the VI. Use as normal with the red and black DMM cables.
Executable Instructions
1. First, you must download the NI-DAQmx for myDAQ driver from this link:https://decibel.ni.com/content/docs/DOC-39065.
2. Download the attached file (Digital Multimeter.zip) and save a local copy on your computer.
3. Once inside the folder, navigate to the Digital Multimeter.app and double click to open.
4. Choose your device from the drop down list and press run.
Changes from Windows Version
This instrument is nearly unchanged from its Windows version. The two differences are that the continuity tester does not make the beep sound when it is “GOOD” and the Help button does not launch the full LabVIEW Help window.
Disclaimer
This instrument is posted as an example for myDAQ for Mac OS X. While it is not an officially supported part of the DAQmx for Mac OS software, we have found it to work without issue. If you run into any issues apart from those noted above, please let us know by posting below.
