After updating from v0024k to v0024o, a message appeared about resetting to default and the need for calibration. When you press the button, there is a calibration error. After requesting 300 mV, always switches to 0.5X, even if set to 1X. Reducing the calibration voltage from 300mV to 150mV does not solve the problem.

Thank you so much for such a great job. You are a genius and a miracle worker. You turn from a simple oscilloscope into a pro. Or maybe these oscilloscope files will help you. If only we could take ready-made preset settings from there. For example, injectors, ignition and so on. And to embed them in this oscilloscope, in general, would be super. I attached the files.https://drive.google.com/file/d/1FF634-UiKT6iGMONAH68AHNmDZ_gfGDl/view?usp=sharing

upload picture, video, or text. no apk thank you

You are a good tester. Fixed? Test it

tokar · « **Reply #2153 on:** March 26, 2024, 01:59:51 pm »

Yes, calibration was successful. Thank you.

I tried to show in detail how the oscilloscope for diagnostics from the Launcher works. If it were possible to embed even a little bit into this oscilloscope, it would be just a cannon.

Hello, I would like to know if I calibrated the oscilloscope correctly, the calibration was with batteries and alternating resist, and I think the temperature does not show correctly, thanks in advance for the answer!

tokar · « **Reply #2156 on:** March 28, 2024, 12:14:18 pm »

If a clock module is installed, then turn it on in the menu, and then it will show the normal temperature.

Manual, this topic page 82.

Hi, yes would be nice to make some presets, like for current clamp hantek cc65 / cc650, etc .
many people use this scope like second on field for automotive use..

Just bought this scope and install last 24x version, and is great, just waiting for power source 0-30v to calibrate ,,
seams that without calibration wont work, as should.

Why this scope don't have at least on one side grid with voltage, for easier signal orientation ?

Do You have some donation account, about this scope development ?

Hello, Temperature sensor does not work on firmware 0.024p

tokar · « **Reply #2160 on:** March 29, 2024, 09:30:59 am »

Works.

gadak · « **Reply #2161 on:** March 29, 2024, 05:38:39 pm »

Why doesn't it work on my oscilloscope? 0.024l was working!

tokar · « **Reply #2162 on:** March 29, 2024, 06:01:59 pm »

Read messages 2156, 2157 on this page (87).

Could you please advise me why when I press autoset offset on the calibration screen it shows a value of 486 on both channels? And the voltage goes from actual 15 volts to 14.6 volts

Atlan · « **Reply #2164 on:** March 30, 2024, 02:26:42 pm »

Picture and video

I didn't have time to deal with the exact numbers. I will come back to it when I have more time.

If a DC signal is measured and there is an offset, the offset is shifted on the AD converter. The value for the displacement is not linear with the value of the AD converter. This pad requires a recalculation of the value.

The obtained value from the AD converter in AC mode is recalculated to the display size on the screen, further calculated to display the measured values, and calculated for the trigger value to match what is on the display.

in DC mode it is more complicated. Based on the DC shift, the values for the trigger, the measured values, the size of the displayed value and the size of the signal shift relative to the center of the AD converter are adjusted.

Transfer of inputs calibration data to sector 708. If they are not damaged, calibration will not be required. It can be called from the menu as before. I don't have time to try if it works, we'll find out when someone new tries to install the firmware.

Hello everyone. Atlan, my big thanks for the great firmware!
But I have small issue.
I got v0.024p and successfully calibrated using car batteries and 5 kOhm potentiometer.
Unfortunately, the channels show the different values, the second one is ok but the first one less by 0.15-0.3V dependent on a value.
I tried to swap the probes but with no effect, the same.
Can it be fixed or is this my oscilloscope's specific?
Thank you.

ADC comp 0 - very suspicious

try to calibrate again and use the 0.024q version

gadak · « **Reply #2168 on:** March 30, 2024, 08:02:55 pm »

On the video I have provided the situation after the first calibration, offset is zero, also the actual voltage corresponds to the actual, but after pressing autoset, the reading decreases by 0.316 and on the calibration page appears offset 0.316. There is also a problem with pressing on the touchscreen when entering the calibration parameters window

Unfortunately, the same.

ADc is not equal zero now but there is the same effect: the 1st channel's readings is less by 0.2V than the 2nd one's.

v0024p. You are not alone. On my device the situation is the same.

v0.024r Stores the position of the horizontal trigger. Adjusted coefficients for offset.

Are you testing it?

Atlan · « **Reply #2172 on:** April 01, 2024, 01:38:11 pm »

Averaging mode v0.024s
I don't know why it's good, but someone wanted it.

facekim · « **Reply #2173 on:** April 01, 2024, 04:15:21 pm »

This is a good idea....I use the osciloscope for automotive too

Atlan · « **Reply #2174 on:** April 01, 2024, 04:45:05 pm »

Beta version, modified AUTOSETUP, needs to be tested, works from 300mV even at 3Mhz
