ScopeMeter® 125: All the power of the 120-Series plus Industrial Bus Health Test capabilities and advanced power measurements on top
The compact ScopeMeter 120 Series is the rugged solution for industrial troubleshooting and installation applications. Based on the Fluke 120 series, the 125 has all the capabilities of the 124 ScopeMeter extended with the capability to measure and analyze the signal quality on the common industrial buses.
For more details on the Industrial Bus Test capabilities of the 125, scroll through this section.

Additional features of the Fluke 125
The Fluke 125 is based on the Fluke 124 and includes all the functions and capabilities of that instrument. On top, a Bus Health Test mode allows for an analysis of the signal quality on industrial buses and networks, comparing measured signals to the standards’ signal requirements.
This section presents the Bus Health Test capabilities of the 125 specifically. For the general test capabilities, see the Fluke 124 pages – click here.
Fluke 125 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 has all the functionality of the 124 plus it comes with the following extensions:
- Bus Health mode gives a clear “Good” / “Weak” / “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 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!
|
The 125 also offers advanced power measurements for single phase and balanced 3-phase systems, a Harmonics Mode and more. For further details on these electrical tests, see the description of the Fluke 125 as it is given with the 120-series here.
