| Rigol DP712 failed for no obvious reason |
| (1/1) |
| AndersJ:
The power supply suddenly failed while delivering 24V at 100mA. It displays "Analog board failed in self-inspection". Any ideas? Sorry about the image size and orientation. I am unable to shrink it, or rotate it. Maybe I am too stupid to own a Rigol. |

Hello I also have a DP711 with the same error, the text comes up immediately when switched on. Have checked what I can check, +14V, -15V, Rectifier, OP Amplifiers etc.. One might suspect "CHIPSEA" CS1232 (Analog to Digital Converter) Can these have a "service menu" where you can go in and see and test functions manually? |
