A four-channel digital oscilloscope-multimeter with Connect-and-View™, ScopeRecord™, TrendPlot™ functions. IP51. Bandwidth: 100 MHz. The Fluke-190-104-III-S series is similar to the Fluke-190-104-III model but includes an activation key for FlukeView software for Windows, transforming the demo version of FlukeView-2 into the full version. The series allows troubleshooting and fault diagnosis during operation. Devices combine durability, portability, and high performance similar to benchtop oscilloscopes, facilitating installation, commissioning, and maintenance of industrial equipment, automation systems, and control processes. High sampling rate, resolution, and deep memory enable precise capture and display of waveform details, noise, and interference. Measurements related to synchronization or amplitude can be performed in three-phase or three-axis control systems, or compare multiple test points in a circuit. Features like the paperless TrendPlot™, ScopeRecord™, Connect-and-View™, and the unique 100-screen playback function help quickly diagnose issues, reducing repair costs and downtime. Fully isolated inputs allow measurements in mixed circuits with different ground reference points, reducing the risk of accidental short circuits. Standard oscilloscopes without specialized differential probes and isolation transformers can only measure with the network ground as reference. The Fluke 190 ScopeMeter® III devices are suitable for a wide range of applications from millivolts to kilovolts, from microelectronics to high-voltage equipment.
