Operating at 500 MHz of bandwidth, it delivers the signal resolution required for complex troubleshooting tasks where a benchtop unit is not practical. The LCD display provides clear waveform visualization in variable lighting conditions. With vertical deflection sensitivity ranging from 2 mV\/div to 100 mV\/div, technicians can capture both low-level signals and higher-amplitude waveforms without switching instruments. This unit is built for licensed electricians, instrumentation techs, and industrial service professionals who require a rugged, portable measurement platform.\u003c\/p\u003e\u003cp\u003eThe FLUKE-190-504-III-S is suited for residential and commercial electrical systems, motor drive diagnostics, power quality analysis, and control circuit verification. It is particularly applicable in environments where four simultaneous signal channels are needed to compare waveforms, verify phase relationships, or diagnose variable frequency drive outputs. The portable form factor makes it practical for both in-panel work and equipment-side diagnostics without requiring a fixed test station.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e500 MHz bandwidth supports high-frequency signal capture for demanding diagnostic tasks\u003c\/li\u003e\n\u003cli\u003eFour independent input channels allow simultaneous multi-signal comparison\u003c\/li\u003e\n\u003cli\u003eVertical deflection range of 2 mV\/div to 100 mV\/div provides broad measurement sensitivity\u003c\/li\u003e\n\u003cli\u003eLCD display delivers clear waveform readout in variable ambient lighting\u003c\/li\u003e\n\u003cli\u003ePortable design suited for field service and on-site electrical diagnostics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a portable oscilloscope for general-purpose electrical and electronic signal diagnostics across industrial, commercial, and trade service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is intended for use by qualified electrical and instrumentation technicians familiar with oscilloscope operation and measurement safety. De-energize or isolate circuits where possible before connecting probes, and follow all applicable NEC and facility lockout\/tagout procedures. Verify probe ratings are appropriate for the voltage levels being measured before making contact. Do not exceed the input voltage rating of the instrument or its probes.\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: 500 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\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-190-504-III-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLUKE","offers":[{"title":"Default Title","offer_id":51538990760242,"sku":"FLUKE-190-504-III-S","price":10550.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7018765b6bf8d31e70a14995791ff21_663f3e4f-353d-4f49-a00a-aedcdc10bb81.jpg?v=1785832017","url":"https:\/\/voomisupply.com\/products\/fluke-fluke-190-504-iii-s-portable-oscilloscope-500-mhz","provider":"Voomi Supply","version":"1.0","type":"link"}
