Measurements using Multimeter Measuring voltage: Testing for proper supply voltage is usually the first step when troubleshooting a circuit. Plug the black test probe into the COM input jack. Plug the red test probe into the V input jack. If the DMM has manual ranging only, select the highest range so as not to overload the input.

Touch the probe tips to the circuit across a load or power source in parallel to the circuit. View the reading, being sure to note the unit of measurement. Below are the steps on how to make resistance measurements. Turn off power to the circuit. Connect the probe tips across the component or portion of the circuit for which you want to determine resistance. This means opening the circuit and using the DMM test leads to complete the circuit.

Below are the steps on how to make current measurements using digital multimeter. Cut or unsolder the circuit, creating a place where the meter probes can be inserted. Plug the red test probe into the amp or milliamp input jack, depending on the expected value of the reading.

Connect the probe tips to the circuit across the break so that all current will flow through the DMM a series connection. Turn the circuit power back on. Average-sensing works for a perfect sinewave. Average-sensing meters typically measure RMS high for voltage and low for current where there is waveform distortion.

True-rms meter or clamp accurately measures both distorted waveforms and sine waves. What is Crest Factor? For current measurement, the higher the CF, the greater the waveform distortion.

CF spec is important for current clamp, since current distortion is typically higher than voltage distortion. Why Choose Fluke Multimeter? Fluke designs its DMMs to the latest, most demanding safety standards. Fluke offers many DMMs with different combinations of features like Touch Hold, analog bar graphs, and enhanced resolution.

Accessories for high current and temperature measurements are available to extend the capabilities of fluke multimeter. Sharing is caring:.
