Hantek6022BL - noise near 0 mV

Sir, Hantek6022 can't measure 0.01mV, it is not so high accuracy.

Hello!

I'm tring to use Hantek6022BL ...

Sir, In fact, the precision of this low cost oscilloscope is really not high.
When you connect your probe to ground, did you connect the grounding clamp of the probe to ground?
The feeler of the probe is exposed to the air, the probe will receive some noise.
Please ensure that the ground is connected correctly.

Hi Amy,

Do you say that the device needs grounding?

Sir, the grounding clamp of the probe needs to be grounded.

Hi Amy,

Dantek 6022BL, soft .v 1.0.6, drivers ODM, OS Win'7'32.

1. The .rfc file is used to be the reference waveform. The ref waveform only loads one channel waveform at a time. So It can't save two channels waveform in .rfc file.
2. The self calibration process is very fast. No error hints indicate the success of calibration.
3. The interpolation is only available when the timebase is less than or equal to 2us.
4. Please upload some pictures to study.
5. This is just a conversion tool. When you use a 10 attenuation probe to measure your signal, you can select x10. The others are the same.
