Question about System Power Supplies
Our dc power supply HP 6654A is showing error message E12. we dont have a manual for this hence pls guide us to solve this problem
This indicates a failure during Power-on Self test that there is a fault with the DACS or secondary VDAC/IDAC readback.
If a simple on/off cycle of your power supply doesn't resolve the problem, your supply will require servicing.
