Precision laser alignment made easy
The rugged Fluke 831 has an intuitive guided user interface that enables quick and complete shaft alignment without advanced training or complicated programs. And while it’s easy to use, laser alignment with the Fluke 831 is powerful enough for the skilled technician. You can cover more of your machines with all the functionality needed on the plant floor, from thermal growth to user defined tolerances and more.

Reduce costs by avoiding downtime
Misalignment causes at least half of all damage to rotating machinery, studies show. Instead of fixing the problem, teams often just treat the symptoms of misalignment and replace bearings, couplings, and seals because they think alignment takes too long.
Contrary to expectations, laser alignment can be fast and easy. So, every machine that is repaired and overhauled should be aligned – not just a few. Teams that embrace laser alignment can save thousands of dollars per year by avoiding downtime and energy waste and reducing the number of bearings and seals they have to replace.

Key features
• Fast, easy, and precise alignment that adapts to your needs.
• Rugged build and the highest-in-class IP rating.
• Single-laser technology for the fastest, most accurate laser alignment.
• Cloud connection enables real-time collaboration.
• Use up to 8 measurement points to achieve precision alignment on vertical machines.

Applications

- Microelectronics

- Troubleshooting



Measure from mV to kV safely



Independently isolated inputs allow you to make measurements in mixed circuits having different ground references reducing the risk of accidental short circuits. Conventional bench oscilloscopes without special differential probes and isolation transformers can only reference measurements to line power earth ground. ScopeMeter 190 Series III test tools are engineered to cover a wide application range from mV to kV, so you’re ready for anything from microelectronics to heavy duty higher voltage electrical applications. 190 Series III 60 MHz and 100 MHz configurations include VPS421 100:1 probes for higher voltage applications, while the 200 MHz and 500 MHz configurations include VPS410-II 10:1 probes suitable for both microelectronics and higher voltage applications.



IP-51 rated for harsh environments



Rugged and shock-proof, ScopeMeter Test Tools are built for dirty, hazardous environments. With its sealed case, it can endure dust, drips, humidity and airborne pollutants. Every time you reach for ScopeMeter Test Tool you can be confident it will work reliably wherever your work takes you.



USB and Wi-Fi connectivity



The Fluke 190 Series III offers two USB ports, electrically isolated from measurement input circuits allowing you to quickly and easily transfer data to a PC, archive and share waveforms with OEMs, colleagues and support staff, or store waveforms, screen captures and instrument setups onto USB memory devices for later use. Easily transfer saved files via USB stick, direct connection via the USB interface or optional Wi-Fi connectivity. These files can be used for further data handling or in FlukeView-2 Software to study waveforms in greater detail.



Connect-and-View triggering



Connect-and-View triggering provides an instant, stable display without the need for adjusting settings. If you’ve used other scopes, you know how tricky triggering can be. If settings are incorrect, results can be unstable or incorrect. 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. It’s especially fast and convenient when you’re measuring a number of test points in rapid succession.



Built-in digital multimeter



Conveniently switch from waveform analysis to precise multimeter measurements using the built in 5000 count digital multimeter on two channel 190 Series III models. 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.



TrendPlot paperless recorder— records up to 11 days to help you find intermittent faults



The toughest faults to find are those that happen only once in a while. These intermittent events can be caused by bad connections, dust, dirt, corrosion, or simply broken wiring or connectors. Line outages, dips, swells and interruptions, or the starting and stopping of a motor can also cause a machine to stop. You may not be around when it happens, but the 190 Series III ScopeMeter Test Tool will be.

- Plot minimum and maximum peak values and average over time

- Plot any combination of up to four readings including voltages, amps, temperature, frequency and phase for all inputs, all with time and date stamp to pinpoint faults
