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

Product Description

The FLUKE FLUKE-190-102-III-S is a portable oscilloscope designed for field and bench diagnostics across electrical, HVAC, and industrial control applications. It delivers a 100 MHz bandwidth across 2 independent channels with an LCD display, giving technicians a clear, real-time view of waveforms in tight or remote work environments. Vertical deflection ranges from 2 millivolts per division to 100 millivolts per division, supporting a wide range of signal amplitudes. The unit weighs 4.8 pounds, making it practical for single-hand carry on service calls. Licensed electricians, HVAC controls technicians, and industrial maintenance professionals are the primary installers and users of this instrument.

This oscilloscope suits residential and light commercial service work where a compact, portable waveform measurement tool is needed. It is well matched for diagnosing variable-frequency drives, ECM motor controls, low-voltage building automation circuits, and general electrical troubleshooting. The 2-channel configuration allows simultaneous comparison of two signals, which is useful when verifying phase relationships or timing between control board outputs and actuator responses.

Key Features

• 100 MHz bandwidth supports accurate capture of fast-switching signals in motor drives and control circuits
• 2 independent input channels for simultaneous dual-signal measurement
• Vertical deflection range of 2 mV/div to 100 mV/div accommodates both low-level and higher-amplitude signals
• LCD display provides clear waveform readout in field conditions
• Portable form factor at 4.8 pounds for single-technician carry

Compatibility

Designed as a general-purpose portable oscilloscope suitable for electrical and electromechanical diagnostic work in residential, commercial, and light industrial settings.

Installation Notes

This instrument is used by licensed electricians, HVAC controls technicians, and industrial maintenance professionals. Before connecting probes to any live circuit, verify the instrument's CAT rating is appropriate for the voltage level being measured and de-energize circuits whenever safe to do so. Follow NFPA 70E arc flash and shock hazard protocols when working on energized equipment. Keep probe grounds isolated from unintended circuit references to prevent measurement errors or equipment damage.
