oscilloscopeThree-dimensional testing for industrial systems »

Inspect input signals, output feedback loops or safety interlocks simultaneously to find a range of problems including:

  • Circuit voltage/current overloading
  • Signal timing measurements and synchronization issues
  • Attenuation/input impedance mismatch
  • Signal fluctuation/drift



Three-phase testing for diagnosing VSD, power inverters, and converters »

  • Test for harmonics, transients and loads at the three-phase power input
  • Troubleshoot dc to ac converters for faulty IGBT gates or filter circuits
  • Test PWM output for reflections and transients or voltage unbalance



Safely measure from mV to kV

Standard probes that cover a wide application range from mV to kV prepare you for anything from micro-electronics to heavy duty medium voltage electrical applications. Independent isolated inputs eliminate the risk of accidental ground short circuits by allowing you to make measurements in mixed circuits with separate ground references.

Take on the Harshest Conditions with the only IP-51-rated Scope on the Market Rugged and shock-proof, all ScopeMeter® portable oscilloscopes are built for harsh environments. Their sealed cases protect them from dust, water vapor, drips, humidity and airborne pollutants, ensuring reliable accurate performance every time you need them.



Meter mode

Built in multimeter to quickly and conveniently perform precise measurements

Built-in digital multimeter 4 channel model with isolated dual input scope and dedicated digital multimeter. Conveniently switch from waveform analysis to precise multimeter measurements using the built in 5000 count digital multimeter. Measurement functions include Vdc, Vac, Vac+dc, resistance, continuity and diode test. Measure current and temperature using suitable shunt, probe or adapter with wide range of scaling factors.



Work a Full Shift on a Single Charge

New high-performance batteries take advantage of Li-ion technology to keep you going strong for up to seven hours. And with the easy-access battery door you can make battery swaps fast.



scopemeter usbCapture and Share Waveforms Easily with New USB connectivity

Two USB ports, electrically isolated from measurement input circuits offer you easy USB connectivity to a PC or USB memory devices. Store unlimited waveform, screen captures or instrument steups to a USB memory device. Connect to a PC USB interface to transfer and archive critical measurement data using FlukeView software for windows.



See a Stable Display Instantly with Connect-and-View&trade Triggering


Connect-and-View™ automatically sets up correct triggering by recognizing signal patterns. Without touching a button, you get a stable, reliable, and repeatable display of virtually any signal including motor drive and control signals. Expedites measuring several test-points in rapid succession.



Record Up to 48 Hours of High-Resolution Waveforms with ScopeRecord™oscilloscope

ScopeRecord memory stores up to 30,000 data points per channel, capturing intermittents and fast glitches. (Two sets of multiple-channel recordings can be stored for later analysis.)

  • Stores events like motion profiles, UPS, power supply, and motor start-ups
  • With the Stop-on-Trigger mode, the ScopeMeter® 190-104 automatically recognizes a power failure and stores the waveform data preceding it
  • With the waveform zoom (up to 100x) you can look at the smallest details, like individual power cycles


Record up to 22 days with TrendPlot™ paperless recorder to find intermittent faultsoscilloscope

Intermittent faults can be caused by bad connections, dust, dirt, corrosion, or simply broken wiring or connectors. Line outages, sags, or starting and stopping a motor can also cause a machine to stop. The TrendPlot function in the Fluke ScopeMeter® test tool helps find those faults by:

  • Plotting minimum and maximum peak values and average over time up to 22 days
  • Plotting any combination of voltages, amps, temperature, frequency and phase for all four inputs, all with time and date stamp to pinpoint faults
