Use the answers to choose the most suitable model from the table below.
| How precise and accurate do your measurements need to be? * | |
| 5½ to 8½ digits | The higher the digits of resolution, the more precise your measurements will be. |
| What types of measurements do you need to make? | |
| See below | General purpose DMMs provide many measurement types. Higher performance DMMs provide greater accuracy and speed. |
| How fast do you need to make measurements? | |
| Readings/sec | Speed indicates how fast the instrument can take measurements. The 34465A, 34470A, & DM34461A provide up to 50,000 readings/sec. |
* Precision = resolution x repeatability
Accuracy = deviation between measured and true value
