Understanding the Subtleties of Specifying
and Applying a 6½
-digit
Low cost, high precision DMMs are increasingly popular
choices for electrical measurement applications, but
they require additional system configuration considerations to
apply them properly in order to realize higher accuracies.
This seminar covers precision test and measurement applications for an emerging class of low cost (<$1000 USD) 6½-digit digital multimeters. Learn how to assemble a testing error budget for various applications for electronic devices and products and then how to select and use an appropriate DMM to satisfy your testing needs. Examples include simple test programming to support automatic acquisition and evaluation of measurement data, as well as basic front panel operation of Keithley’s newest 6½-digit DMM, the Model 2100.
Intended Audience
This seminar is recommended for development and test engineers and scientists who need to make high precision electrical measurements using widely available, highly accurate 6½-digit DMMs. Those who want to gain a better understanding of the subtleties of specifying and applying such meters will learn some basic tools and methods for assembling an error budget, as well as tips on selecting a DMM for basic test applications.
What you will learn:
- How to establish a measurement accuracy budget for an application
- How to account for central and parasitic sources of error
- How to match your accuracy requirements with the appropriate DMM
- How to calculate system test uncertainties and errors
