The 189 was the first Fluke handheld DMM that offered two ways to measure AC volts. In the Vac function, the measurement was essentially the same as most Fluke DMMs, but the 189 also allows you to measure ac volts while in the Vdc function.
The latest technology available combines a digital multimeter with a thermal imager and adds wireless capabilities so measurements can be taken from a safe distance, saved and even stored in secure data centers for later analysis.

The most popular reason for paralleling conductors is to provide higher ampacity than a single conductor can provide. "In a typical building design, the largest conductors are usually 500 kcmil or 600 kcmil". "And many electrical contractors will actually object to 600 kcmil. If ampacity above 400 A is necessary, using parallel conductors is the only reasonable solution.
Astronomers from the University of New South Wales (UNSW) in Australia have been working in Antarctica's interior since 1996. In collaboration with astronomers from France, Italy and the United States, they're seeking the perfect location for the next generation of deep-space telescopes.
Find out what the hidden dangers of making voltage and current measurements with a tester that does not have the fuse protection that was designed into the tester - dangers than can cause serious burns, and possibly even death.
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 detection and the absence or presence of voltage testing.
The application note explains what kind of logging these meters can perform, how to use the recording feature, and the information that can be provided to you. This note also discusses how FlukeView Forms PC software is used to increase the power of the Recording feature.
Read success stories from ONSITE PC Assitance owner Robert Johns. Working on mostly low voltage equipment for home offices and small-to-medium business, Johns uses the Fluke 116 to measure for low voltage, auto-ranging and min/max temperature.
Expert Chuck Newcombe compares digital multimeters of yesterday with today's DMMs with true-rms ac measurement capability. Get the facts about the subtle points you should know when making rms measurements.
Making sure that equipment delivers peak performance at all times requires ongoing troubleshooting on the part of maintenance technicians. Depending on the size and scope of the facility, operations will change over and produce many different products and packages in varying size runs.
Founded in 1997, LIFETECH S.R.O. develops, designs and distributes equipment for water and air treatment and purification. The company also services its equipment, as well as equipment made by other manufacturers. Lifetech has about twenty employees overall, with five in the Development Department.
HSI Security Systems installs, maintains and monitors electronic life-safety systems throughout Northwest Oregon and Southwest Washington. We're an electrical contractor that specializes in low voltage systems and rudimentary electrical controls.
In the world of handheld digital multimeters, maintenance professionals are being deluged with new models, new manufacturers, new functionality, claims about ruggedness, claims about water- and dust-resistance - the list goes on and on.
In 1949, a bright engineer named John Fluke devised an alternative to the cumbersome and difficult analog meters he worked with and sold his invention to GE.In 1955 he and his team came up with the idea for the differential voltmeter as a means to solve a production problem - to improve production efficiency.
