Fluke FLUKE-190-204-III-S Portable Oscilloscope 200mhz 4CH

Product Description

The FLUKE FLUKE-190-204-III-S is a portable oscilloscope designed for field diagnostics and hands-on electrical troubleshooting by licensed electricians, industrial technicians, and service professionals. Operating at a bandwidth of 200 MHz across 4 independent channels, it captures complex waveforms simultaneously from multiple circuit points. Vertical deflection ranges from 2 mV/div to 100 mV/div, giving technicians fine resolution for low-level signals alongside the dynamic range needed for higher-amplitude readings. An integrated LCD provides clear waveform display in a handheld, battery-compatible form factor suited for work in the field or on the bench.

This oscilloscope is suited for industrial, commercial, and residential electrical diagnostics where portability is required. Typical applications include variable frequency drive troubleshooting, motor drive analysis, power quality checks, and control signal verification in HVAC, building automation, and industrial equipment. With 4 channels, it supports simultaneous comparison of input and output signals, trigger analysis, and phase relationship checks without the need to swap probes between test points.

Key Features

• 200 MHz bandwidth supports capture of high-frequency transients and fast-switching signals
• 4 independent channels enable simultaneous multi-point waveform capture
• Vertical deflection range of 2 mV/div to 100 mV/div for broad signal amplitude coverage
• LCD display provides clear waveform visualization in variable lighting conditions
• Portable form factor supports field use outside a fixed bench environment

Compatibility

Designed as a portable handheld oscilloscope for use with standard oscilloscope probes and accessories compatible with the FLUKE ScopeMeter 190 series platform.

Installation Notes

This instrument is installed and operated by qualified electricians or instrumentation technicians. Always de-energize and isolate the circuit under test before attaching or removing probes where safe to do so, and verify probe CAT ratings match the measurement environment before use. Follow applicable NFPA 70E arc flash and electrical safety procedures when working on energized systems. Store the unit in its protective case when not in use to prevent damage to the display and probe connectors.
