Fluke Digital Multimeter - DMM Verification Concepts and Uncertainty Types

©Fluke Calibration 2011 Basics Of Measurement Uncertainty for DMM Calibration 22
First – lets look at the concept
Our initial look –
• Consider verifying a
precision digital multimeter
• With a hypothetical study
of verifying the DMM’s
measurement performance
at 100 millivolts DC
• Let’s briefly look at what
measurement uncertainty
could be in this case
