Key Features:
A three-in-one tool
 ScopeMeter 120 Series combines a 40 or 20 MHz dual input digital storage oscilloscope, two true-rms digital multimeters and a dual input TrendPlot recorder all in a compact, battery powered instrument. Leave all other test tools behind because the ScopeMeter 120 Series test tool is the only one you’ll need.
 Connect-and-View™ triggering for an instant, stable display
 Scope users know how difficult triggering can be. Incorrect settings show unstable and sometimes incorrect 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 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.
One test lead measures all
 High frequency waveform, meter, capacitance and resistance measurements as well as continuity checks are all covered by the shielded test leads. No time wasted finding or swapping leads. The included accessories allow hook-up at test objects of every dimension.
Use TrendPlot™ to help find intermittents, fast
 The toughest faults to find are those that happen only once in a while – intermittents. They can be caused by bad connections, dust, dirt, corrosion or simply broken wiring or connectors. Other factors, like line outages and sags or the starting and stopping of a motor, can also cause a machine to stop. You may not be around to see it – your Fluke ScopeMeter will. In this “paperless recorder” mode, you can plot the minimum and maximum peak values and average over time – up to 16 days. The two inputs can plot any combination of volts, amps, temperature, frequency and phase – with time and date stamp – to help lead you to the cause of those faults quickly.
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. (See technical specifications for details on battery life.)
Floating measurements, safety certified
While conventional oscilloscopes can only make measurements referenced to power line ground, the Fluke 120 Series makes floating measurements so there’s no risk of an accidental ground short circuit when making a connection. The Fluke ScopeMeter 120 Series test tools and the included shielded test leads are safety certified for measurements on 600 V CAT III industrial power systems. Using the VPS40 probe, measurements up to 1000 V CAT II are fully supported. Via the optically isolated RS-232 interface, the ScopeMeter 120 can be safely connected to a printer for direct print-out or to a PC for later analysis and documentation using FlukeView® Software.
Additional features of the Fluke 125/S
|
Bus Health mode allows for an analysis of the signal quality on industrial network, comparing measured signals to the standards’ signal requirements.
Fluke 125/S is the ScopeMeter of choice for the maintenance engineer who deals with industrial machinery and the industrial network connecting his machinery the like.
The Fluke 125/S comes with the following extensions:
|
- Bus Health mode gives a clear "Good" / "Bad" indication for the electrical signals on industrial buses and networks, such as CAN-bus, Profi-bus, RS-232 and many more. The Fluke 125/S validates the quality of the electrical signals as soon as any electrical signals are passed along the network. It checks the signal levels and speed, transition times and distortion, and compares these to the appropriate standards to help you find errors like improper cable connections and terminators. It helps you find the source of error in case communication comes to a halt. All the commonly found industrial network types are supported!
- 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.
- The 125/S package comes with Flukeview Software, Interface cable and hard carrying case for the Fluke 125 3copemeter.
