Fluke FLUKE-190-502-III-S Portable Oscilloscope 500 Mhz

Product Description

The FLUKE FLUKE-190-502-III-S is a portable oscilloscope built for field and bench diagnostics by electricians, industrial technicians, and test engineers. It delivers 500 MHz of bandwidth across 2 input channels, making it capable of capturing fast transients and complex waveforms in electrical, HVAC control, and industrial drive systems. The LCD display provides clear waveform visualization in a variety of lighting conditions. Vertical deflection ranges from 2 mV/div to 100 mV/div, covering low-level signal work through higher-amplitude measurements. At 4.8 pounds, the unit is portable enough for panel-side and equipment-room use without sacrificing measurement performance.

This oscilloscope is suited for residential and commercial electrical troubleshooting, industrial equipment diagnostics, and verification of control signals in building automation, variable frequency drives, and power conversion systems. The 2-channel configuration allows simultaneous comparison of two signals, which is useful for phase relationship checks, trigger isolation, and input-versus-output analysis on inverters and motor drives. It is a practical tool for licensed electricians and instrumentation technicians working in the field or on the service bench.

Key Features

• 500 MHz bandwidth supports capture of fast transients and high-frequency signal content
• 2 input channels enable simultaneous dual-signal measurement and comparison
• Vertical deflection range of 2 mV/div to 100 mV/div for broad signal amplitude coverage
• LCD display provides clear waveform readout in field and shop environments
• Portable form factor at 4.8 pounds supports field service use

Compatibility

Designed as a portable handheld oscilloscope for general electrical and industrial diagnostic applications where 500 MHz bandwidth and dual-channel input are required.

Installation Notes

This instrument is operated by licensed electricians and qualified instrumentation technicians. Always de-energize or isolate circuits to the extent permitted by the measurement task before connecting probes, and confirm the voltage category rating of probes and leads before use on energized equipment. Follow NFPA 70E arc flash and shock hazard requirements when working on live panels. Store the unit in its protective case when not in use to prevent probe and connector damage.
