FLUKE 190-104-III/S ScopeMeter test tool
The Fluke 190-104-III/S is a portable ScopeMeter for troubleshooting and measurements in electrical and automation systems. It combines an oscilloscope with a digital multimeter, allowing users to view signal waveforms and perform standard electrical measurements with the same instrument.
This type of equipment is typically used when a fault cannot simply be identified by a voltage or current reading. In such cases, it is useful to be able to track a signal over time, compare multiple measurement points, and quickly gain an overview when a machine, frequency converter, or control system is not behaving as expected.
With four channels, multiple signals can be viewed simultaneously, and the isolated inputs enable measurements in circuits with different ground references. This is an important feature in industrial systems, where both control signals and higher voltages are often present. The instrument is safety-rated for CAT III 1000 V and CAT IV 600 V, making it suitable for demanding field measurement work.
ScopeRecord and TrendPlot make it easier to capture intermittent faults. In practice, this means the instrument can record over time, allowing users to go back and see what happened just before the problem occurred. This is particularly relevant for sporadic outages, noise, downtime, and other faults that are difficult to catch the moment you are at the facility.
There is also a built-in multimeter function, allowing users to quickly switch between waveform analysis and more traditional measurements without changing tools. This saves time during systematic troubleshooting.
