In this example, a four wire resistance measurement is made with a NI USB-4065 digital multimeter.

Place the blocks:

• CONNECTION USB4065
• RESISTANCE 4W USB4065
• READ USB4065
• BIG NUMBER

First ensure the 4065 blocks have the correct instrument set in the parameters. Run the app to perform a reading.

Note the RESISTANCE 4W USB4065 block has an optional parameter to take a single reading. However, the READ USB4065 block can be used to make the same measurement multiple times without changing any settings.
