A faster sample rate and higher bandwidth mean greater accuracy and clarity. The scope will capture and display unknown waveform shapes, amplitudes, and any disturbances. To display at least the fifth harmonic component of a signal, a good rule of thumb is to select a scope with a bandwidth of at least five times the maximum clock rate of the device being tested. The faster the sample interval, the more accurate and detailed the scope will display a signal edge (dV/dt) and peaks of any reflections or transients.

Three-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 according to IEC60529

Rugged and shock-proof, the portable oscilloscope is built for harsh environments. The sealed cases protect them from dust, water vapor, drips, humidity and airborne pollutants, ensuring reliable and accurate performance every time you need them.

Work a full shift on a single charge

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.

Capture and share waveforms easily with 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 waveforms, screen captures or instrument setups 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™ 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™

ScopeRecord memory stores up to 30,000 data points per channel, capturing intermittents and fast glitches.

• Stores events like motion profiles, UPS power up signals, power supply AC and DC signals, and motor start-ups
• With the Stop-on-Trigger mode, it automatically recognizes a power failure and stores the waveform data preceding it
• With the waveform zoom you can look at the smallest details like individual power cycles

Record up to 22 days with Trendplot™ paperless recorder to find intermittent faults

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 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

Applications

• Plant maintenance
• Microelectronics
• Power electronics
• Industrial

Using Fluke Thermal Imaging to Troubleshoot Motors & Drives

Infrared cameras, also called thermal imagers, are useful for troubleshooting motor problems as well as for monitoring motor condition for preventative maintenance in power generation, manufacturing and commercial plants. Thermal images of motors reveal their operating condition as indicated by surface temperature. Such condition monitoring is important as a way to avert many unexpected motor malfunctions in systems that are critical to manufacturing. The onset of motor failures can often be detected by a variety of techniques, including vibration, ultrasound and thermal imaging.

In this article, we cover why use thermal imaging and what to scan, as well as some notes on what to look for, including shaft misalignment.
