The Fluke 124B/NA 2-Channel Industrial ScopeMeter Hand-Held Oscilloscope, 40 MHz, 40 MS/s is the rugged oscilloscope solution for industrial electrical and electro-mechanical equipment troubleshooting and maintenance applications. It is a truly integrated test tool with oscilloscope, multimeter and high-speed recorder in one, easy-to-use instrument. The 124B/NA also integrates with Fluke Connect mobile app and FlukeView for ScopeMeter software to enable further collaboration, data analysis and archiving of critical test information.

The 124B/NA includes innovative functions designed to help technicians troubleshoot faster and get the answers they need to keep their systems up and running. Display waveforms with Connect and View trigger and setup technology and 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 with Auto Reading

Connect-and-View Triggering for Instant, Stable Display

Oscilloscope users know how difficult triggering can be. Using the wrong settings can lead to unstable waveform captures, and sometimes the wrong measurement data. Fluke's 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.


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

Validate System Power

Industrial Equipment Needs Reliable Power Supply

To operate properly, use the dual input to obtain key power measurements. For single phase or 3-phase balanced systems, the dual inputs of the 124B/NA can measure AC+DC RMS voltage on channel A and AC+DC RMS current on channel B.

Harmonic Spectrum

Harmonics Measurements

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.

One Test Tool

One Test Lead to Measure Multiple Electrical Parameters

High frequency waveform, meter, capacitance and resistance measurements as well as continuity checks are all covered by a single set of shielded test leads. No time is wasted finding or swapping leads.

Fluke Connect Mobile App Compatibility

Automated industrial machinery is harder than ever to trouble shoot. It is not enough to just know where you have to test, you also have to know what to look for - and that can be difficult without baseline measurement data or access to subject matter experts. The Fluke Connect Assets wireless system of software and wireless test tools enables technicians to reduce maintenance costs and increase uptime with accurate equipment records and maintenance data that is easy to interpret and share. Compare and contrast test point measurement data and trends so that you can better understand signal characteristics and changes over time. And, by storing maintenance data on the Fluke Cloud you can enable team members to access it from wherever and whenever they need to, so that you can get advice or approvals in the field.

Quickly step through recorded events to identify and troubleshoot intermittent faults Click for larger image

Troubleshoot Intermittent Faults

Use Comprehensive Recorder Modes to Help Find Intermittent Faults

The toughest faults to find are those that happen only once in a while. These intermittent events 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 the 124B/NA will. You can either plot the minimum and maximum peak measurement values or record the waveform trace. And with expandable micro SD 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. You can quickly step from one tagged event to the next, while still having access to the full data set.

Industrial Field Bus

Industrial Bus Health Test Verifies Electrical Signal Quality on Industrial Buses

Bus Health Test analyzes the electrical signals on the industrial bus or network, giving you a clear "Good", "Weak" or "Bad" indication mark for each of the relevant parameters, which is presented next to the actual measurement value. Measured values are compared to standard values, based on the selected bus types (CAN-bus, Profi-bus, Foundation Field, RS-232 and many more), or unique reference values can be set, if different tolerances are required.
