Checking for live stock

The Fluke 125B/UK is designed for engineers who need to view real signals directly on the job, not at a bench. With a 40 MHz bandwidth and two isolated channels, it handles control signals, sensor outputs, and power electronics found in production equipment and building systems. Being handheld means it goes straight to the fault location, whether that is inside a control cabinet, on a machine frame, or in a plant room.

Salient Features and Benefits of the Fluke 125B/UK Handheld Digital Oscilloscope

  • Captures waveforms on two independent channels for comparison and timing checks.
  • 40 MHz bandwidth supports most industrial control, drive, and switching signals.
  • Built-in digital multimeter covers voltage, resistance, and continuity for quick checks.
  • ScopeRecord mode allows long recordings to catch intermittent faults that don’t appear instantly.
  • Connect-and-View triggering automatically stabilises the signal without constant manual adjustment.

Built for On-Site Signal Work

The strength of the 125B/UK is that it removes guesswork when signals don’t behave as expected. Instead of relying only on multimeter readings, engineers can actually see what the waveform is doing. It helps confirm whether noise, timing issues, signal dropout, or power-quality problems are causing a fault. The rugged housing, battery operation, and isolated inputs make it safe to use on live systems where bench equipment would be impractical or unsafe.

Application Versatility of the Oscilloscope

  • Troubleshooting variable-speed drives, PLC inputs, and feedback sensors.
  • Checking timing and signal integrity in automation and control systems.
  • Diagnosing unstable signals in power supplies and converters.
  • Maintenance work on machinery.
  • Service and commissioning tasks.
