If anyone with a 3045X wants to test the 3055 in his DMM, I can easily prepare an .ADS. BUT, no responsibility for my side. |

I've done some bash correction to correctly use XML calibration file. Now the value displayed is correct and the result is very interresting. I'm investigate to display digits with a little lower font size. With the input shorted to the ground : |

--- Quote ---How to test the sdm-mod ? (only with the latest 1.01.01.19 firmware) Step 1 Plug a formatted FAT32 USB Key (I use 4GB) into the SDM3055 Step 2 Connect to telnet (username:root, password:ding123) Step 3 Backup all Siglent data into the USB key : "cp -R /usr/bin/siglent /usr/bin/siglent/usr/mass_storage/U-disk0/" After copying, unplug the USB key Step 4 Plug the USB key into your computer Copy "sdm-mod.app" into the "/siglent" of the USB key Unplug the USB key Step 5 Plug the USB key into the SDM3055 and go to telnet Stop the current sdm.app application : use "ps" to list all application PID and kill the "./sdm.app" PID. Generally it's the PID 550, you could kill it with command "kill 550" Step 6 Prepare and run the mod "mkdir /usr/bin/siglent/usr/mod" "cd /usr/bin/siglent/usr/mod" "cp -R /usr/bin/siglent/usr/mass_storage/U-disk0/siglent/ /usr/bin/siglent/usr/mod/" "cd siglent" "./sdm-mod.app" Step 7 To stop sdm-mod.app, just press "Control C". Restart the device to return to normal operation. Step 8 To remove the mod folder "rm -r /usr/bin/siglent/usr/mod" --- End quote --- --- Code: ---sdm-mod.app 20190812 v01 SHA1 : 85ceab5b27570de364ab127d0c67a7deb17903ab SHA256 : d26b360d6db9a89b058b4d44a2116c546b492e402df37fa1d491276a415fd5d0 Features - Add 2 digits (7 1/2 digits) Drawback - On some menu the sign and/or the last digit is not display correctly --- End code --- |
