Digital Multimeter Tutorial
Digital Multimeter Tutorial Learning Center
A digital multimeter (DMM) is an electrical measurement instrument that can be used to troubleshoot a wide range of electrical problems. A typical digital multimeter will have the ability to measure volts, ohms, and amperes.
The digital multimeter tutorials found here will provide you with some fundamental information to select a digital multimeter and how to get the most out of your Tektronix / Keithley digital multimeter, including how to make accurate resistance measurements and how to easily calculate measurement statistics.

Answers to the most common DMM questions, including: How do I make my DMM measure faster? What is the difference between sensitivity, resolution & accuracy?
|10 Steps to Digital Multimeter Selection|
Digital multimeters seem common, but specialized versions perform tests you might not imagine, thereby improving productivity and lowering costs. Read the 10 steps for selecting a DMM.
|Tips and Techniques for Efficient DC Testing and Current-Voltage Characterization|
This e-guide explores some of the most common DC current vs. voltage (I-V) tests being performed today, the seemingly inherent complications posed by each, and how new techniques can help to not only overcome these challenges but enhance efficiency and productivity.
|How to Make Simple and Accurate Resistance Measurements|
Using two wires to measure resistance is convenient, but causes measurement error. Learn how you can enable four-wire resistance measurements with just two leads.
|How to Accurately Measure Nanoamperes|
Accurately measuring low-level leakage currents in the nanoampere range is a challenge for most digital multimeters. Learn tips on measuring standby current and how to accurately measure nanoamperes.
|How to Use Measurement Statistics and Histograms|
Measuring the output voltage of a power supply is a common measurement on a digital multimeter. However, taking that measurement and understanding how stable the output of the power supply requires time-consuming and often complex measurement statistics. Learn how you can simplify calculations of measurement statistics when analyzing your device.
|Datalogging with TrendPlot™|
Troubleshooting elusive problems requires logging large quantities of data or tracking measurement trends over time. Learn how the unique capabilities of TrendPlot™ on the Tektronix DMM4050 and DMM4040 can be used to simply address this.
