Remove Resistance, Current, and Frequency Measurement Errors in DMMs

Introduction When you make measurements with a digital multimeter (DMM), common errors will occur. This white paper covers the types of measurement errors for resistance, DC and AC currents, including frequency and period. You will learn how to eliminate potential measurement errors to achieve the highest accuracy with a DMM. Key factors causing resistance measurement errors with a DMM: <ul> <li>Long leads create a voltage drop across the leads. </li> <li>Lower DMM resistance range generates higher test current, which may affect sensitive DUT with a large temperature coefficient. </li> <li>Large resistance range changes require proper measurement settling delays. </li> <li>Current leakages on test leads and fixtures affect high resistance measurements.</li> </ul>

Eliminate Measurement Errors and Achieve the Greatest Accuracy Using a DMM

When making measurements with a digital multimeter (DMM), common errors such as signal interference, external noise, and internal current leakage will cause measurement errors. Understanding the root cause of these errors will help you eliminate and achieve the greatest accuracy possible using a benchtop multimeter. This white paper helps you to uncover several sources of system cabling and DC voltage measurement errors, such as: • Radio frequency interference • Thermal EMF errors • Noise caused by magnetic fields • Noise caused by ground loops • Common mode rejection • Noise caused by injected current • Loading errors due to input resistance • Loading errors due to input bias current It also covers ways to overcome the above errors to get the accuracy you need.
