Fluke ScopeMeter 190 204 III Portable Oscilloscopes

The Fluke ScopeMeter 190-204-III Portable Oscilloscopes is versatile, handheld instruments designed for troubleshooting and maintaining electronic systems. Here are some key features and specifications:

Handy high-performance oscilloscopes for harsh environments

The Fluke 190 Series III ScopeMeter® is designed for use anywhere and for almost any troubleshooting task. They provide a high level of safety in the CAT III 1000 V/CAT IV 600 V measurement classes and combine ruggedness and handling with the high performance of a benchtop oscilloscope. This means you can easily master the installation, operation and maintenance of industrial machinery, automation and process control as well as power conversion electronics – from DC to 500 MHz.

Two- and four-channel models are available as well as different sampling rates and bandwidths. Fast sampling rate up to 5.0 GS/s, resolution up to 200 ps and large memory for 10,000 sample points per channel enable highly accurate acquisition and detailed display of waveforms, noise and other signals. Make measurements involving timing or amplitude on three-phase systems or three-axis drives, or simply compare multiple measurement points in the circuit under test. Features like TrendPlot™ recording, ScopeRecord™ mode, Connect and View™ activation, and unique 100-screen playback help you quickly diagnose problems to minimize repair costs and downtime . Thanks to these features, the oscilloscope can be used simply and flexibly, especially for diagnosing the most difficult problems, such as complex signal patterns, inductive noise, event signal interruption, fluctuation or deviation.

Automatic capture of the last 100 screen contents
In oscilloscope mode, the instrument ALWAYS saves the last 100 screens – without prior setup by the user. If an anomaly occurs, the entire event history can be displayed on the screen as often as desired using the REPLAY button. The measuring device can be set up to detect glitches or intermittent anomalies and then detects up to 100 predefined events in “babysitter mode”.
ReplayManual or continuous repetition. Displays the 100 recorded screen contents as a “live” animation, or manually controlled. Each screen has a date and time marker.
Playback memoryTen sets of 100 screens each can be saved internally for later analysis. Save additional sets directly to external flash memory drive on USB host port.

Signal shape comparison and pass/fail check
Waveform comparisonAllows storage and display of a reference waveform for visual comparison with newly acquired waveforms. The reference is derived from a captured waveform and can be edited in the oscilloscope.
Pass/fail testIn waveform comparison mode, the oscilloscope can be set to save only matching (“good”) or only non-matching (“bad”) waveforms to the playback memory bank for further analysis.
