Introduction
This example application demonstrates how to use a Model DMM7510 to make a high-accuracy DC
voltage measurement.
This type of test is often done in metrology labs, where high accuracy is required for calibration and
verification.
Equipment required
• One Model DMM7510
• Two insulated banana cables (you can use the Model 1756 Standard Test Lead Kit that is
provided with the Model DMM7510, or equivalent)
• One device or component to be tested
• For the SCPI and TSP command examples, one computer set up for communication with the
Model DMM7510
Device connections
You can use either the front or rear input terminals for this test. Both front-panel and rear-panel
connections are safety banana jacks. Note that you must use either the front terminals or the rear
terminals — you cannot mix front and rear connections.
Make sure that the front-panel TERMINALS switch is set to the terminals you are using. F displayed
next to the switch indicates that the instrument is reading the front-panel terminals. R indicates that
the instrument is reading the rear-panel terminals.
Make the following connections:
• Connect the test leads to the INPUT HI and LO terminals.
• Connect the INPUT HI connection to one of the DUT leads.
• Connect the INPUT LO connection to the other DUT lead.
The physical connections for the front and rear panels are shown in the following figures.
