Fluke ScopeMeter 190-204/S III Oscilloscope

The Fluke 190-204/S represents a portable oscilloscope engineered for field service professionals. As the first four-channel portable scope rated CAT III 1000V/CAT IV 600V, this instrument combines 200 MHz bandwidth with real-time sampling rates up to 2.5 GS/s and 200 ps resolution. The device features deep memory capacity of 10,000 samples per channel, enabling detailed waveform examination, and maintains an IP-51 rating for dust, drip, humidity, and temperature resistance.

The instrument enables three-dimensional industrial system testing by simultaneously inspecting input signals, output feedback loops, and safety interlocks. Applications include three-phase power testing for VSD inverters, harmonics analysis, and transient detection. Independent isolated inputs prevent accidental ground shorts in mixed circuits with separate ground references.

Built-in digital multimeter functionality provides VDC, VAC, resistance, continuity, and diode measurements through the 5000-count meter. Extended battery life using Li-ion technology supports approximately seven hours of operation. USB connectivity allows waveform storage and PC data transfer via FlukeView software. Features include Connect-and-View automatic triggering, ScopeRecord memory for up to 48 hours of high-resolution capture, and TrendPlot function for tracking intermittent faults over 22 days.
