Fluke FLUKE-190-202-III-S Portable Oscilloscope 200 Mhz

Product Description

The FLUKE FLUKE-190-202-III-S is a portable, dual-channel oscilloscope designed for field and bench diagnostics across electrical, HVAC, and industrial control applications. Operating at a 200 MHz bandwidth with two input channels and a built-in LCD display, it gives technicians real-time waveform visibility in tight service environments where a benchtop unit is impractical. Vertical deflection ranges from 2 mV/div to 100 mV/div, supporting a wide range of signal amplitudes from low-level control circuits to higher-voltage drive signals. Weighing 4.8 pounds, the unit is compact enough for one-person carry without sacrificing measurement capability.

This oscilloscope is suited for licensed electricians, HVAC controls technicians, and industrial maintenance professionals working on variable frequency drives, motor control circuits, building automation systems, and low-voltage wiring. Its portable form factor makes it practical for on-site troubleshooting where desktop instruments cannot be brought to the equipment. The dual-channel configuration allows side-by-side waveform comparison, which is useful for diagnosing phase relationships, signal timing, and control board output verification.

Key Features

• 200 MHz bandwidth supports fast signal capture on motor drives and control circuits
• 2 independent input channels allow simultaneous waveform comparison
• Vertical deflection range of 2 mV/div to 100 mV/div covers low-level and higher-amplitude signals
• Built-in LCD display provides on-site waveform readout without external monitors
• Portable design at 4.8 pounds suits field service and mobile diagnostics

Installation Notes

Installation and operation of this oscilloscope should be performed by a qualified electrician or instrumentation technician familiar with voltage measurement safety practices. Always de-energize and lock out circuits before attaching or removing probes where possible, and verify probe voltage ratings before connecting to any circuit. Follow applicable NFPA 70E arc flash safety guidelines when working near energized equipment. Consult the manufacturer documentation for probe calibration and input channel configuration before first use.
