It delivers 100 MHz of bandwidth across 4 independent channels with an LCD display, allowing technicians to capture and compare multiple waveforms simultaneously. Vertical deflection ranges from 2 millivolts per division to 100 millivolts per division, supporting a wide range of low-level signal measurements. This instrument is designed for licensed electricians, industrial service technicians, and advanced HVAC controls specialists who require reliable waveform analysis outside the shop.\u003c\/p\u003e\u003cp\u003eThe FLUKE-190-104-III-S fits residential and commercial service applications where technicians need to diagnose variable-frequency drives, motor controls, low-voltage control circuits, and building automation systems. Its 4-channel configuration allows simultaneous monitoring of multiple signal paths, making it well suited for comparing input and output waveforms during commissioning or fault diagnosis on complex control boards and inverter-driven equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100 MHz bandwidth supports high-speed signal capture on industrial and HVAC control circuits\u003c\/li\u003e\n\u003cli\u003e4 independent input channels for simultaneous multi-signal measurement\u003c\/li\u003e\n\u003cli\u003eVertical deflection range of 2 to 100 millivolts per division for low-level signal sensitivity\u003c\/li\u003e\n\u003cli\u003eLCD display for clear waveform visualization in varied lighting conditions\u003c\/li\u003e\n\u003cli\u003ePortable form factor designed for field service use outside a lab or shop environment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a portable field oscilloscope for use by electrical and controls technicians across residential, commercial, and light industrial service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis oscilloscope is installed and operated by qualified electricians or instrumentation technicians. Always de-energize and verify circuits are safe before connecting probes to live control panels or motor drives when measurement conditions allow. Follow NEC guidelines and site-specific lockout\/tagout procedures before attaching to any energized equipment. Refer to the FLUKE user manual for probe category ratings and input voltage limits before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOscilloscope Type\u003c\/strong\u003e: Portable Oscilloscope\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBandwidth\u003c\/strong\u003e: 100 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Vertical Deflection\u003c\/strong\u003e: 100 mV\/div\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Vertical Deflection\u003c\/strong\u003e: 2 mV\/div\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 15.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 19.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLUKE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FLUKE-190-104-III-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLUKE","offers":[{"title":"Default Title","offer_id":51538928271666,"sku":"FLUKE-190-104-III-S","price":8337.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64a6f241e9f31ea38c190640cb92e6b8.jpg?v=1785829945","url":"https:\/\/voomisupply.com\/products\/fluke-fluke-190-104-iii-s-portable-oscilloscope-100mhz-4ch","provider":"Voomi Supply","version":"1.0","type":"link"}
