Dir sir,
For calibration, disconnect any probes or cables from the input connectors.
About the latest software, you can send a mail to support@hantek.com to get.
Please test it on win7, convenient for us to find the reason. Thank you for your cooperation.
Dir sir,
I want to send a software to you. Please give me your email.
Please install the latest software to try.
If not, please change a Win7 computer to try.
By the way, please unplug the probe to do self calibration.
Here is a dropbox link to the video. It shows the entire calibration sequence including moving the probe from the ground to the 2vp-p ref signal once the cal is complete. You will see the square wave on the screen show about 6vp-p. You will also notice at about 2:45 in the video, the application locks up. Unplugging the USB and re-plugging it recovers from the lock up. I have experience this issue ever since I received the unit. It that normal? The application also tends to lock up if I grab the trigger voltage symbol on the right side of the screen and slide it. The software version here is 1.0.8.
At one point the device calibrated correctly on Windows 7 BUT I have not gone back and tried that since upgrading the computer to Win 10. I currently do not have the software installed on a windows 7 machine. I will do some testing tonight and capture some video to send to you. I doubt Windows 10 had anything to do with the calibration issue. I would think that is all contained inside the 3204A.
Sir,
The device can work on Win7 normally?
When you do self calibration, do you input any signal to 4 channels? Please don't input any signal to try.
About the voltage measurement, please give us a short video to study.
