so, is it possible to hack 2d42 to make it 2d72? |

The procedure is described in a few posts back. If you try it just make sure to backup your device before do any change. |

Good morning everyone. I'm Brazilian and I need help from geniuses. I have the 2C42 with the latest firmware that now appears for example in a sinusoid to FREQUENCY, MAX AND MIN. What would this MAX and MIN be? Because when it had the option of peak to peak the values gave different. In a 3db sinusoid I get the RMS value and multiply it by 1.4142 and find the peak value where multiplied by 2 I find the peak-to-peak value. Well these values did not hit before and now with this update. I calibrated the tip x10 and x100 and nothing. Please someone help me? Thank you. FIRMWARE 2019030201 FPGA V04 PCB 000000001 |

Hello crsojr welcome to the forum. I saw your other post on Hantek's forum as well. The values showed by the device are correct. If I understood correctly, you are just mixing the concepts of peak-to-peak and maximum and minimum values. I can understand the confusion because in the earlier versions of the firmware this scope used to show the peak-to-peak measure, in the latest FW Hantek changed it to show the MAX and MIN, that is the maximum (or minimum) amplitude of the signal from zero (ground). This may help you: or http://www.newtoncbraga.com.br/index.php/ideias-dicas-e-informacoes-uteis/177-ideias-praticas/12290-tensao-de-pico-eficaz-e-rms-ip1315 |

Hello Microchip grateful for your response. I understood what you wrote. I expressed myself wrong. What happens is that before the old firmware when it appeared the option pico-pico the value was not correct. Ex. In the sinusoid at 60 Hz in 3 db the peak value is the RMS value x 1.4142. When I put the oscilloscope to measure the peak-to-peak value that should be 2 x peak went wrong. So I updated the firmware of 2C42 where it now shows MIN MAX but it still shows wrong values .. I left 2 videos in google drive one with the tip x10 and another with the tip x100. Please see it. There is a true rms multimeter with sinusoid value where the peak value should be rms * 1.4142. I can not find any parameters for this result on the oscilloscope. Can you help me ? Thank you very much.
