Measuring voltage is foundational for anyone using a digital multimeter. Learn how to measure AC voltage in this step-by-step article. Working with direct current? Follow the steps in this easy-to …

Find out what dual impedance and voltage detection are and why it's good to have them built into your multimeter. Find out about impedance basics, ghost voltages, non-contact voltage …

To ensure maximum accuracy of a dc voltage measurement, first measure and record the ac voltage. Then measure dc voltage by selecting a dc voltage range (using the RANGE button) …

To measure the AC output voltage at either the drive or the motor terminals: Plug the black test lead into the common jack and the red test lead into the V/W jack.

With a digital multimeter, you can check the line input voltage, but depending on the type of distortion, a voltage reading alone may not reveal whether a problem exists. Noise, distortion, …

Only the first two tools are commonly used, and both can accurately measure standard (pure ac) sinusoidal waveforms. Yet a true-RMS meter is widely preferred because it is the only one that …

Use a multimeter when you need precise voltage, resistance, or low-current measurements, especially when troubleshooting circuits. Learn the differences and similarities between clamp …

Bring on the calculator. You can first measure the ac voltage and then the dc, recording both values. Next, you square both terms and add these squared values together. Finally, you take …
