Product overview: Fluke 120B Series Industrial ScopeMeter handheld Oscilloscopes

Simplified testing, more insight

The compact ScopeMeter 120B Series, is the rugged oscilloscope solution for industrial electrical and electro-mechanical equipment troubleshooting and maintenance applications. Its a truly integrated test tool, putting the functions of an oscilloscope, multimeter, and high-speed recorder into one, easy-to-use instrument. The ScopeMeter 120B Series also integrates with Fluke Connect mobile app and FlukeView  for ScopeMeter software to enable further collaboration, data analysis, and archiving of critical test information.

Faster electro-mechanical troubleshooting

Troubleshoot faster and get the answers you need to keep systems up and running. Display waveforms with Connect and View trigger and setup technology. Automatically view related numerical measurements using Fluke IntellaSet technology, all without making manual measurement adjustments. With Recorder Event Detect capabilities, elusive intermittent events are captured and logged for easy viewing and analysis

Connect-and-View triggering for an instant, stable display

Oscilloscope users know how difficult triggering can be. Using the wrong settings can lead to unstable waveform captures, and sometimes, even the wrong measurement data. Flukes unique Connect-and View triggering technology recognizes signal patterns, and automatically sets up the correct triggering to provide a stable, reliable, and repeatable display.

Connect-and-View triggering is designed to work with virtually any signal, including motor drives and control signals— without adjusting parameters, or even touching a button. Signal changes are instantly recognized, and settings are automatically adjusted providing a stable display even when measuring multiple test points in quick succession.

IntellaSet/AutoReading

The Auto Readings function with Fluke IntellaSet technology uses proprietary algorithms to intelligently analyze the measured waveform and automatically display the most appropriate numerical measurements on-screen, so you can get the data you need easier than ever before. For example, when the measured waveform is a line voltage signal, the V rms and Hz readings are automatically displayed, whereas if the measured waveform is a square wave, the V peak-peak and Hz readings are automatically displayed. Using IntellaSet technology in conjunction with Connect and-View automatic triggering you can be sure youre seeing not only the correct waveform, but the appropriate numerical reading as well. All without touching a button.

Harmonics function measures periodic distortions

Harmonics are periodic distortions of voltage, current, or power sine waves. Harmonics in power distribution systems are often caused by non-linear loads such as switched mode dc power supplies and adjustable speed motor drives. Harmonics can cause transformers, conductors, and motors to overheat. In the Harmonics function, the Test Tool measures harmonics to the 51st. Related data such as dc components, THD (Total Harmonic Distortion), and K factor are measured to provide a complete insight into the electrical state of health of your loads.

Comprehensive recorder modes help find intermittent faults

The toughest faults to find are those that happen only once in a while—intermittent events. They can be caused by bad connections, dust, dirt, corrosion or simply broken wiring or connectors. Other factors, like line outages and sags or the starting and stopping of a motor, can also cause intermittent events resulting in equipment shutdowns. When these events happen, you may not be around to see it. But your Fluke ScopeMeter Test Tool will.

You can either plot the minimum and maximum peak measurement values or record the waveform trace. And, with expandable microSD memory, recording sessions can be done for up to 14 days. This recorder is even more powerful with the addition of Recorder Event Detect, which makes detecting and logging intermittent faults easier than ever. Just set a threshold on a meter reading or scope trace and deviations are tagged as unique events. You no longer need to search through masses of data to pinpoint faults and can quickly step from one tagged event to the next, while still having access to the full data set.
