  • Automatic measurements
  • A dual-input TrendPlot™ recorder
  • Connect-and-View™ trigger simplicity for hands-off operation
  • Shielded test leads for oscilloscope, voltage, resistance and continuity measurements
  • 10:1 Voltage Probe included with Fluke 124 and 125 for high frequency measurements
  • Up to 7 hours battery operation
  • 600 V CAT III safety certified
  • Optically-isolated interface for PC connection
  • Rugged, compact case
  • Fluke 125 gives bus health and power measurements


In today’s complex systems, a meter measurement just doesn’t give enough detail to determine the cause of a fault. Signal anomalies, dropouts and glitches that might cause a machine to go down, are best displayed with an oscilloscope. The ScopeMeter 120 Series meet today’s need of simultaneously measuring and checking waveforms. The unique Connect-and-View™ triggering automatically displays stable waveforms of virtually any signal. It really is as easy as one-two-three!

ScopeMeter 120 Series combines a 40 or 20 MHz dual input digital storage oscillo-scope, two true-RMS digital multimeters and a dual input TrendPlot™ recorder all in a compact, battery powered instrument. Leave all other test tools behind, the ScopeMeter 120 Series is the only tool you’ll need

Battery powered mobility
Up to seven hours of battery operation frees you from mains outlets for true on-the- move working. The handheld format and the weight of just 1.2 kg, make the instrument easy to carry and to fit comfortably in your hand. The rugged and drip proof case assures long life and reliable operation in the harshest industrial environments.

Floating measurements, safety certified
While conventional oscilloscopes can only make measurements referenced to power line ground, the Fluke 120 Series make floating measurements so there is no risk of an accidental ground short circuit when making a connection. The ScopeMeter 120 Series and the included shielded test leads are safety certified for measurements on 600 V CAT III industrial power systems. And using the VPS40 probe, measurements up to 1000 V CAT II re fully supported! Via the optically isolated RS-232 or USB interface, the ScopeMeter 120 Series can be safely connected to a printer for direct print-out or to a PC for later analysis and documentation using FlukeView software. 

Scope users know how difficult triggering can be. Wrong settings show unstable and sometimes wrong results. Fluke’s unique Connect-and-View recognizes signal patterns, and automatically sets up correct triggering. It provides a stable, reliable and repeatable display of virtually any signal - including motor drive and control signals - without you touching a button. Signal changes are instantly recognized and settings adjusted for a stable display. Benefit from the speed and convenience when measuring a number of test points in quick succession.

Based on the 124, the Fluke 125 offers additional test capabilities for measurements on industrial machinery and industrial buses. 

Furthermore, the 125 offers the following additional capabilities for tests on industrial machinery:

 

  • Power Measurements for single phase and balanced 3-phase systems. The Fluke 125 can directly present you the Total Power (Watts), Apparent Power (VA), Reactive Power (VAR) and the Power Factor (PF), over a wide range of applied frequencies, including those seen with motor drives and inverters. As a result, you are able to easily see the effects on the various power measurements during start-up or under changing operational conditions. A current clamp is included as a standard.
  • Harmonics mode graphically displays harmonics up to the 33rd harmonic to assist in fault-finding, e.g. with large non-linear loads.
  • RPM and Hz reading for use with electrical and combustion engines.
  • Vac pwm for use on motor drive outputs, reading the true output voltage experienced by the motor itself.
  • Low impedance measurements giving a 0.01 ohms resolution for motor windings and the like.

FlukeView® for Windows® helps you get more out of your ScopeMeter by:

  • Documenting - transfer waveforms, screens and measurement data from the ScopeMeter to a PC. Print or import the data into your report.
  • Add user text to individual ScopeMeter settings – providing guidance to the operator when recalling a set-up.
  • Archiving - create a library of waveforms with your comments for easy reference and comparison. Store complete Replay cycles for analysis of waveform changes. Store complete memory content of the ScopeMeter on your PC for back-up purposes.
  • Waveform Compare – store reference waveforms on the PC, or send a reference back to the ScopeMeter for waveform comparison and “Pass/Fail testing.
  • Analysis - use cursors, perform spectrum analysis or export data to other analysis programs. ScopeMeter test tools are connected to a PC via an optically-isolated RS-232 or USB interface cable.
