Hi, is there already a zero calibration for the probes in R6.
My 3205 always displayed -2,5mv. In R5 I can zero it, but did not find this option in R6.

Hello Fred,
You can use the 'Axis Scaling' > 'Offset' feature to zero the probe offset.
Please refer to section 7.2.1 Advanced Options Menu in the User Guide (http://www.picotech.com/document/pdf/psw6-en.pdf).
Regards

Hi John,
Changing the offset will also change the Y values, that is no calibration. When I short the probe the reading is still -2.5mV, i need to use that value as zero.
Also in the FFT screen there is a peak in bin 0 (DC value) when the input is not calibrated. Measuring small signals "At Peak" will select the bin 0 (0 Hz) (Maybe that bin need to be skip in selecting the Peak bin, or a new range between ruler 1 and 2).

Fred,
You are correct about the differences in the offset effect between PS5 and PS6, and though it is intended to eventually incorporate the majority of PS5 features into PS6, it is not possible for me to define the order of implementation or timescales involved.

Hi John,
Ok, I understand that not every thing is present in the new release now.
I'm new on this list but are you maintaining a problem and change list for this new software release. Can I keep on posting my request for the software in this list?
The new software PS6 is in my point of view so much better than the old one, I hope there will be many new releases with new features in it.
Thanks,
Fred |

Hi,
I still have some problem's with the zero calibration of my 3205 scoop. The unit read a DC average of -2.2mV with a closed probe.
There is still no correction in the R6 software (in R5 it is there) and is it very enoiing when using the spectrum display. There is always a strong signal at 0Hz (bin 0) of -18dBV.
Is there a possibility to add the zero correction or to calibrate the hardware?
Thanks,
Fred Krom |

Hi i think you refer to what was in PicoScope 5 as offset null. This feature is something that we are thinking of implementing and may be on our to do list.
Kind regards. |

Hi ziko,
The offset null is what I mean, Yes.

That is very vague!
