Fluke FLUKE-190-102-III Portable Oscilloscope 100 Mhz

Product Description

The FLUKE FLUKE-190-102-III is a portable, two-channel oscilloscope built for field diagnostics and bench troubleshooting across electrical, HVAC, and industrial control applications. Operating at a 100 MHz bandwidth, it delivers reliable waveform capture on live circuits, motor drives, control boards, and low-voltage systems. The color LCD display provides clear signal visualization in varying light conditions. Vertical deflection ranges from 2 mV/div to 100 mV/div, giving technicians the resolution needed to inspect both low-level signal noise and larger voltage swings without switching instruments.

This oscilloscope is suited for licensed electricians, HVAC controls technicians, and industrial service professionals who need a portable, rugged diagnostic tool in the field. Typical use cases include verifying waveform integrity on variable frequency drives, inspecting control signal outputs on building automation systems, testing motor run capacitor circuits, and diagnosing intermittent faults on low-voltage control wiring. Its compact form factor makes it practical for panel work and equipment rooms where bench space is limited.

Key Features

• 100 MHz bandwidth supports accurate capture of fast-switching signals on motor drives and control boards
• Two independent input channels allow simultaneous comparison of reference and test signals
• Vertical deflection range of 2 mV/div to 100 mV/div accommodates both fine signal detail and larger waveforms
• LCD display provides clear waveform readout in field and shop environments
• Portable form factor sized for field service and panel diagnostics

Compatibility

Designed as a general-purpose portable oscilloscope suitable for use across electrical, HVAC controls, industrial automation, and low-voltage signal testing applications.

Installation Notes

This instrument is intended for use by qualified electricians and instrumentation technicians familiar with safe measurement practices on live circuits. Always verify probe ratings are appropriate for the voltage levels being measured before connecting to a circuit. Follow NFPA 70E arc flash safety requirements when working inside energized electrical panels. Power down equipment under test when connecting or disconnecting probes wherever safe de-energization is feasible.
