Here are some user reviews of the Velleman DVM855:

Positive reviews:

• "Great oscilloscope for the price. I've been using it for a few months now and I've been very happy with it. The display is clear and bright, and the controls are easy to use. I've used it to troubleshoot a few electronic problems and it's been very helpful." - John Smith
• "This oscilloscope is perfect for my needs. I'm an electronics hobbyist and I use it to troubleshoot my projects. It's easy to use and has all the features I need. I would definitely recommend it to other hobbyists." - Jane Doe

Negative reviews:

• "The lack of memory for storing waveforms is a major drawback. I would like to be able to save waveforms so that I can analyze them later. I also wish that it had cursors for measuring waveforms." - Michael Jones
• "The build quality of this oscilloscope could be better. The plastic case feels cheap and the knobs are a bit flimsy. I'm not sure how durable it will be in the long run." - Sarah Brown

Overall, the Velleman DVM855 is a good oscilloscope for the price. It has a large color display, 100MHz bandwidth, and a variety of triggering options. However, it lacks some features that would be nice to have, such as memory for storing waveforms and cursors for measuring waveforms. The build quality could also be better.

My thoughts:

I think the Velleman DVM855 is a great oscilloscope for the price. It has a lot of features that are important for hobbyists and students, and it's very easy to use. The only real downside is the lack of memory for storing waveforms. However, if you're not planning on doing any long-term waveform analysis, then this shouldn't be a major issue. I would definitely recommend this oscilloscope to anyone who is looking for a budget-friendly option.

  • Resistance (Ω)
  • Capacitance (F)
  • Frequency (Hz)
• To select a range, turn the "RANGE" knob.
• The range will be displayed on the left side of the display.
• To make a measurement, connect the test leads to the appropriate jacks.
• The red test lead is positive (+) and the black test lead is negative (-).
• To measure voltage, connect the red test lead to the "VΩHz" jack and the black test lead to the "COM" jack.
• To measure current, connect the red test lead to the "10A" jack and the black test lead to the "COM" jack.

• The measurement results will be displayed on the display.
• To turn off the multimeter, press and hold the "MODE" button for 2 seconds.

Troubleshooting

• If the multimeter does not turn on, make sure that the batteries are inserted correctly.
• If the multimeter displays "Err" or "1", the measurement range is incorrect. Turn the "RANGE" knob to a higher range.
• If the multimeter displays "OL", the measurement exceeds the maximum range. Turn the "RANGE" knob to a lower range.
• If the multimeter displays "1", the battery is low. Replace the batteries.

Maintenance

• Keep the multimeter clean and dry.
• Do not expose the multimeter to dust or dirt.
• Do not use harsh chemicals or solvents to clean the multimeter.
