Fluke 120B Series Industrial ScopeMeter handheld Oscilloscopes

Great Portable Oscilloscope for testing VFD's and power conditions if not on a Delta. This is my first one and don't know how we survived without one. If you are working with Delta transformer I recommend a 190 Series and with only 2 inputs you cannot data you may want. Went with the 125B to save a little cost over the 190 and very happy with it. This has really helped with properly diagnosing VFD issues we were having and recording intermittent issues. I would recommend!

I have used many scopes and meters in the 25+ years of my career and there is no comparison. Fluke makes some of the best products of this type in the world, I would choose no other without compromise.

We bought this scope ( Fluke 125 ) to troubleshoot several Fieldbus trunks. Tool was able to find noise and distortion affecting this site where other tools from different vendors couldn't. It was a nice feeling finding the "smoking gun"

We purchased Fluke 125B scopemeters for use in the electrical labs at the community college where I am a professor, and I found them to be extremely useful when educating students about AC wave forms, AC power (true power (watts), apparent power (VA), reactive power (VAR) and power factor). I also use the meters when teaching about power quality and harmonics. The color display is so much better then the black & white display on the 43B. I have only been using the meters for one semester but so far I have found them to be excellent and durable. The students learn the concepts so much easier when they can see the waveforms for themselves on a meter display, on the projector screen, or on their cell phone using Fluke connect. Our Fluke representative, Curt Geeting, has always been a big help when choosing Fluke products to best suit our needs.

Purchased the 124B few months ago. I mostly use it to measure the voltage waveform of VSD and UPS, which help me to solve the problems quickly and safely. However the device works great, but i found that there is something odd when measuring DC voltage i.e. The voltage value will change while moving the waveform position up and down. Firmware version V1.12.00

We have repeatedly provided information but have problems with the software and still can not resolve it.

We bought it in July 2018 124B. The recording feature should help us find periodic errors. We find that scoped restarts and timestamps do not match the recorded image. We have contacted fluke several times, but it does not seem to be resolved.
