Fluke Digital MultimetersSolutions for every need
How to choose the bestDMM for your jobChoosing the right digital multimeter (DMM) requires thinkingabout what you’ll be using it for.Evaluate your basic measurement needs and job requirementsand then take a look at specialfeatures/functions built intomany multimeters. Think aboutwhether you need to do basicmeasurements, or if you needthe more advanced troubleshooting options offered by specialfeatures.CAT ICAT IICAT IIIServiceEntranceCAT IVMeterServiceEntranceFactors to consider:Underground Service Your work environment (voltagelevel, types of equipment, typesof measurements, applications) Specialty features/functions(capacitance, frequency, temperature, non-contact voltage,low impedance mode, min-maxrecord, data logging, trending) Resolution and accuracy(6,000, 20,000, or 50,000count resolution)SafetyThe increased occurrence andlevels of transient overvoltagesin today’s power systems havegiven rise to more stringentsafety standards for electricalmeasurement equipment. Transients that ride on top of powersources (mains, feeder or branchcircuits) can trigger a sequenceof events that may lead to seriousinjury.
