Please disconnect all signal connections, and perform self-calibration 30 minutes after power on. Author: Lam Time: 2022-1-18 03:20 Edited by Lam at 2022-1-18 04:48
[attach]4828[/attach][attach]4820[/attach]Received new firmware to flash but got worst than before.
I updated FLASH correctly follow the instructions and files sent to me. I check the oscilloscope CH#1 and CH#2. They are worse than before.
That was NOT successful. I have the same error code: 511d6 again when activate Utility->Calibration->Offset (no inputs connected and 30 minutes warm up).
CH1 : zero line is lower than the zero scale by 800mV ( "ZERO" button) and when connected to the test square ware it is reading lower (4V not 5V)
CH2: zero is good but test 5V square wave it is reading very lower by about 50%.
Firmware loaded : 3102
