Fluke 120B Series ScopeMeter® Industrial Handheld Oscillometers

Simplified testing for deeper, faster electromechanical troubleshootingThe ScopeMeter® 120B Series is a compact, ruggedized oscilloscope for industrial electrical and electromechanical equipment troubleshooting and maintenance applications. An easy-to-use test tool that combines an oscilloscope, multimeter, and high-speed recorder, the ScopeMeter 120B Series is also compatible with the Fluke Connect® mobile app and FlukeView®, which enables in-depth collaboration, data analysis, and archiving of critical test information through ScopeMeter software.

Connect-and-View™ Triggering for Instantaneous, Stable Displays

Oscilloscope users know how difficult triggering can be. Using the wrong settings can result in unstable waveform capture and sometimes even incorrect measurement data. Fluke's unique Connect-and-View™ triggering technology recognizes signal characteristics and automatically sets the correct trigger to provide a stable, reliable, and repeatable display.Connect-and-View™ triggering is specifically designed to work with virtually any signal, including motorized drive and control signals-without the need for parameter adjustments or even the touch of a button. Signal changes are immediately recognized and settings are automatically adjusted to provide a stable display, even for fast, continuous measurements of multiple test points.

IntellaSet™/Automatic Readout

With Fluke IntellaSet™ technology's Auto-Read feature, a dedicated algorithm intelligently analyzes the measurement waveform and automatically displays the appropriate measurement value on the screen, making it easier than ever to get the data you need. For example, when the measurement waveform is a line voltage signal, the Vrms and Hz readings are automatically displayed, but if the measurement waveform is a square wave, the V peak-to-peak and Hz readings are automatically displayed. With IntellaSet™ technology and Connect-and-View™ automatic triggering, you not only get the right waveform, you get the right reading. There's no need to touch a button.

With Fluke Connect-and-View™ and IntellaSet™ technology, you can quickly access the data you need.

Industrial equipment requires a reliable power supply for proper operation, and the dual inputs enable critical power measurements to be obtained.

For single-phase or three-phase balanced systems, the dual inputs of the industrial ScopeMeter® 120B Series are capable of measuring ac+dc rms voltage on channel A and ac+dc rms current on channel B. The Fluke 125B will then calculate; frequency, active power (kW), reactive power (VA or var), or displacement power factor (PF). The Fluke 125B then performs calculations; frequency, phase angle, active power (kW), reactive power (VA or var), power factor (PF) or displacement power factor (DPF), as well as calculating the power value of a three-phase system when all phases have the same voltage and current. This can be applied to balanced systems and resistive loads.

Easy access to critical power characteristics to verify system power.

Harmonic Measurement

Harmonics are periodic distortions of voltage, current or power sinusoids. Harmonics in distribution systems are usually caused by nonlinear loads such as switched 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 up to the 51st fundamental. Measurements can also be made on DC components, THD (Total Harmonic Distortion) and K-factor, giving a complete picture of the electrical state of healthy loads.

Harmonic spectrum overview with cursor measures the percentage of distortion relative to the fundamental.

Easily Diagnose Intermittent Faults with Comprehensive Recording Mode

Hard-to-find faults are those that occur occasionally - intermittent events. These intermittent failures can be caused by improper connections, dust, dirt, corrosion, broken wires, or broken connectors. Other factors such as line breaks, arc droop, or motor startup and shutdown can also trigger intermittent events that can cause the unit to shut down. When these things happen, you may not be able to detect them right in the field. But these failures are easy to spot with the Fluke ScopeMeter® test tool. You can plot the minimum and maximum values of peak measurements or record waveform traces. Meanwhile, up to 14 days of operation can be recorded on an expandable micro SD memory card. The recorder is also equipped with Recorder Event Detect, making it even more powerful and easier than ever to detect and record intermittent faults. Simply set a queue for meter readings or oscilloscope traces to mark deviations as unique events. You can easily identify faults without having to retrieve large amounts of data and quickly move from one flagged event to the next, while still having access to the complete data set.

Quickly display recorded events so that intermittent faults can be identified and resolved.

Industrial BusHealth Test determines the quality of electrical signals in industrial buses.

BusHealth Test analyzes the electrical signals of an industrial bus or network and gives a clear indication of "good", "weak" or "bad" for all relevant parameters. This is displayed next to the actual measured values. Depending on the selected bus type (CAN-bus, Profi-bus, Foundation fieldbus, RS-232, etc.), the measured values are compared with standard values or, if different tolerances are required, unique reference values can be set. The Fluke 125B verifies the quality of electrical signals as they pass through the network, without having to look at the data content. In addition, the 125B checks signal level and speed, transition times, and distortion, and compares these to appropriate standards to help you detect errors such as improper line connections, poor contacts, grounding errors, or incorrect terminators.

Quickly understand the analog characteristics of the physical layer of industrial fieldbus signals.

Multiple electrical parameters can be measured with one test lead

High-frequency waveform, meter, capacitance, and resistance measurements can be accomplished with only one set of shielded test leads, along with on-off checks. No need to waste time searching for or replacing leads.

In addition to displaying waveforms, a single test tool can measure volts, ohms, amps, or capacitance.

FlukeView® ScopeMeter® Software for Windows

Use the ScopeMeter 120B with FlukeView® software for even more functionality:

• Save a color screenshot of your device to a PC
• Attach screenshots to your reports and documents
• Capture waveform data with the ScopeMeter test tool and save it to your PC
• Create and archive waveform references for easy comparison
• Copy waveform data into a spreadsheet for your detailed analysis.
• Parameter measurement using the cursor
• Adds user comments to instrument settings and sends them to the device for operator reference and use as operating instructions

Note: Some features are limited to specific ScopeMeter Test Tool models.

- Fluke Connect Mobile App Compatibility

Troubleshooting automated industrial machinery is more difficult than ever. It's not enough to know where to test, you also need to know what to look for - which can be especially difficult without baseline measurements or access to experts in the field. Fluke Connect® Assets wireless software systems and wireless test tools help technicians dramatically reduce maintenance costs and increase equipment uptime by delivering accurate equipment records and maintenance data that's easy to interpret and share. Increase equipment uptime. By comparing and contrasting test point measurements and trends, you can get a more complete picture of signal characteristics and changes over time. And by storing maintenance data in the Fluke Cloud™, your team members can access it when and where they need it, so you can get recommendations or approvals in the field and get systems back up and running faster than ever before.
