Measuring DC voltage with high accuracy

High-accuracy DC voltage measurements
This application demonstrates how to use the Model DMM7510 to make a high-accuracy DC voltage
measurement. You can make the measurement from the front panel or over the remote interface
using SCPI code or TSP code. For information about setting up remote communications, see Remote
communications interfaces.
For this application, you will:
• Restart the instrument.
• Select the DC voltage function.
• Set the integration rate to 10 power line cycles (PLCs). At 60 Hz line frequency, 10 PLCs provide
an aperture of 166.7 ms.
• Turn on autozero. This enables the instrument to optimize the accuracy of readings by checking
reference measurements.
• Enable a repeating filter with a count of 100. This reduces noise error because the results are
more stable when the measurements are averaged.
• Generate readings from the front panel or the remote interface.
Using the front panel
Restart the instrument and select the function, integration rate, auto zero, and filter settings:
1. Press the POWER button on the front panel to turn on the instrument.
2. On the FUNCTIONS swipe screen, select DCV.
3. On the top half of the Home screen, select Range.
4. Select the 10V range.
5. Swipe to the SETTINGS swipe screen.
6. Select Rate.
7. Set NPLC to 10.
8. Select OK.
9. Select Input Z.
10. Set the input impedance to Auto.
11. Verify that Auto Zero is set to On.
12. Press the MENU key.
13. Under Measure, select Calculations.
14. Select Filter Config.
15. Set the Filter Type to Repeat.
16. Set the Filter Count to 100.
17. Select OK.
18. Set the Filter to On.
19. Press the HOME key.
