Introduction
This example application demonstrates how to use a DMM7510 to make a high-accuracy dc
voltage measurement.
This type of test is often done in metrology laboratories, where high accuracy is required for
calibration and verification.
Equipment required
•
One DMM7510
•
One computer set up for communication with the DMM7510
•
Two insulated cables with banana plugs
•
One device to be tested
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. When F is
displayed next to the switch, the instrument is reading the front-panel terminals. R indicates that the
instrument is reading the rear-panel terminals.
