Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?:

What were the biggest problems encountered?: The power adapter isn't compatible with the local line voltage (here 230V is use, insead of 120V)

Detailed Review:

Package Content:

The scope came in a cardboard box, and inside I found a nice hard case.




Besides the scope itself, the hard case contained the following:

  • 4 double insulated probe
  • Li-ion battery (4800mAh)
  • USB A-B mini cable
  • CD with FlukeView software and user manual
  • Statement of calibration practice
  • Power adapter (country dependent)
  • Hanging strap

Some important feature:

  • 4 electrically isolated floating inputs up to 1kV, it eliminate the risk of accidental ground short circuits and all input is high speed sampled (2.5GS/s) and provide 200MHz bandwidth
  • IP51 dust- and drip-proof rating so you can use it either in a harsh, dirty and hazardous industrial conditions or in your lab
  • Deep memory: 10,000 samples per channel waveform capture so you can zoom in on the details
  • Advanced automatic measurements, power (Vpwm, VA, W, PF) and time (mAs, V/s, w/s)
  • Isolated USB ports for pendrive and PC connectivity




Connect and view feature:

This feature sets the trigger automatically and when the signal is changes, this feature automatically adjusted the trigger again.

Eligible bandwidth

If you work in a noisy envionment such as high power inverters, or with a noisy waveforms the eligible bandwidth is a good feature. You can choose 3 different bandwidth, 20kHz, 20MHz or 200MHz. It can supress the high frequeny noise. The other way to supress the noise is the averaging function. With this function you can average 2, 4, 8, or 64 consecutive acquistions.

Automatic scope measurements

This scope offers a wide range of automatic measurement. You can choose up to four of the following measurement:

  • Vac
  • Vdc
  • Vac+dc
  • Peak to peak
  • Vpwm
  • Aac (with current probes)
  • Adc (with current probes)
  • Aac+dc (with current probes)
  • Power (Power Factor, Watts, VA, VAr)
  • Phase
  • Frequency
  • Rise & fall time
  • Pulse width (positive & negative)
  • Duty cycle (positive & negative)
  • Temperature (with 1mV/°C sensitivity)
  • dB (dBV, dBm)
  • mAs




Spectrum function

You can select either input to the spectrum function, and you can select three type window (Hanning, Hamming or auto), but the user manual recommend the auto windowing function, because it automatically adapt the part of the signal to a complete number of cycles. This reduces the side-lobes.


100 most recent screen

The scope automatically stores the 100 most recent screens and when you press the hold key, the memory contents are frozen. After this, if you use the replay button you can step back through the stored screens.


Zoom function and cursor measurements



You can measure time, frequency, amplitude with te cursor function.

Rise time measurement


If you choose the auto mode the upper and the lower cursor will automatically move to the trace high, and the reading will display the rise time between te 10% and the 100%.



The scope has two USB connector. The first is a USB host connector to connect a USB stick. It only can handles the stick of maximum 2GB. You can use this port to save screens in .bmp format..

The other connector is a mini-USB connector which allowes you to connect the scope direct to the PC. To use this feature you have to install the FlukeView software, the software is allowes make screen shots, and remote control the scope.


Battery capacity

The scope runs approximately 400 minutes with a full charged battery.

  • Hi DAB,


    Thank you for the questions!  At next week I will add this topics to the review. In fact it is very difficult to write a review of this scope because it has a lot of functions, and I have a little time recently to test it.

  • Good review.


    It looks like Fluke as a good bench testing meter.

    Can you download the screens to a computer?

    Also, how rugged do you think the meter would be in a normal bench environment?

    Have you run a test to see how long the meter runs before it needs a recharge?

    How fast is the data acquisition?


    Just a thought,
