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

Product Description

The FLUKE FLUKE-190-502-III is a portable oscilloscope designed for field and bench diagnostics across industrial, electrical, and HVAC applications. It delivers a 500 MHz bandwidth across 2 independent channels, giving technicians the signal resolution needed to analyze waveforms in motor drives, control circuits, and power distribution systems. The LCD display provides clear waveform visualization in a compact, hand-carried form factor. Vertical deflection ranges from 2 mV per division to 100 mV per division, supporting a broad range of signal amplitudes. Licensed electricians, industrial technicians, and advanced service professionals rely on this class of instrument for live circuit analysis and fault diagnostics.

The FLUKE-190-502-III is suited for residential and commercial electrical service work, industrial automation troubleshooting, HVAC variable-frequency drive diagnostics, and control board signal verification. Its portable design makes it appropriate for use in the field where bench-top instruments are not practical. Technicians working on motor controls, inverters, programmable logic controllers, and low-voltage signal circuits will find the dual-channel configuration useful for comparing input and output waveforms simultaneously.

Installation Notes

This instrument is intended for use by qualified electricians, instrumentation technicians, and licensed trade professionals familiar with live circuit measurement safety practices. Always verify that probe ratings match the voltage category of the circuit under test before connecting. De-energize and lock out circuits where possible before attaching leads, unless live measurement is specifically required by the diagnostic procedure. Follow applicable NFPA 70E arc flash and electrical safety standards when working on energized industrial equipment.
