Fluke 124B OffersCompact and rugged, this oscilloscope is ideal for industrial electrical and electro-mechanical equipment troubleshooting and maintenance applications. Features innovative functions that help technicians troubleshoot faster for quicker results and to keep their systems running smoothly. Additionally, triggering displays waveforms without having to adjust amplitude, timebase, and trigger settings.
Features
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 the wrong measurement data. This instrument's unique Connect-andView 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 displays the most appropriate numerical measurements on the 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 Connect-and-View automatic triggering you can be sure you're seeing not only the correct waveform but the appropriate numerical reading as well. All without touching a button.
Industrial equipment needs a 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 Industrial ScopeMeter 120B Series can measure AC+DC RMS voltage on channel A and AC+DC RMS current on channel B. This oscilloscope can then calculate; frequency, phase angle, active power (kW), reactive power (VA or var), power factor (PF), or displacement power factor (DPF) and can also calculate the power values for a 3-phase system where all phases have equal voltage and currents. This applies to both balanced systems and resistive loads.
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 troubleshoot. It's not enough to just know where you have to test, you also have to know what to look for and that can be hard without baseline measurement data or access to subject matter experts. This 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 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 you can get advice or approvals in the field and get your systems up and running faster than ever before.
Use the comprehensive recorder modes to help find intermittent faults with ease
The toughest faults to find are those that happen only once in a while-intermittent event. 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 them. 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 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, and can quickly step from one tagged event to the next, while still having access to the full data set.
