Fluke Digital Multimeters Solutions for every need

DMM selection chartHow to choose the best DMM for your jobChoosing the right digital multi-meter (DMM) requires thinking about what you’ll be using it for. Evaluate your basic measure-ment needs and job requirements and then take a look at special features/functions built into many multimeters. Think about whether you need to do basic measurements, or if you need the more advanced troubleshoot-ing options offered by special features.

Factors to consider:• Your work environment (voltage

level, types of equipment, types of measurements, applications)

• Specialty features/functions (capacitance, frequency, tem-perature, non-contact voltage, low impedance mode, min-max record, data logging, trending)

• Resolution and accuracy (6,000, 20,000, or 50,000 count resolution)

SafetyThe increased occurrence and levels of transient overvoltages in today’s power systems have given rise to more stringent safety standards for electrical measurement equipment. Tran-sients that ride on top of power sources (mains, feeder or branch circuits) can trigger a sequence of events that may lead to serious injury. Test equipment must be designed to protect people work-ing in this high-voltage, high-current environment.

Measurement category

In brief Examples

CAT I Electronic • Protected electronic equipment

• Equipment connected to (source) circuits in which measures are taken to limit transient overvoltages to an appropriately low level

• Any high-voltage, low-energy source derived from a high-winding resistance transformer, such as the high-voltage section of a copier

CAT II Appliances, PCs, and TVs

• Appliance, portable tools, and other household and similar loads

• Outlet and long branch circuits

• Outlets at more than 10 meters (30 feet) from CAT III source

• Outlets at more that 20 meters (60 feet) from CAT IV source

CAT III MC panels, etc. • Equipment in fixed installations, such as switchgear and polyphase motors

• Bus and feeder in industrial plants

• Feeders and short branch circuits, distribution panel devices

• Lighting systems in larger buildings

• Heavy appliance outlets with short connections to service entrance

CAT IV Three-phase at utility connection, any outdoor conductors

• Refers to the “origin of installation,” i.e., where low-voltage connection is made to utility power

• Electricity meters, primary overcurrent protection equipment

• Outside and service entrance, service drop from pole to building, run between meter and panel

• Overhead line to detached building, underground line to well pump
