| 34401A problems on 4w resistance readings |
| << < (3/3) |
| masterx81:
This morning i've powered it on, immediately tested the front and rear connectors and... it works! No settle time, precise reading I've heared that electrolytics can change they behaviour if leaved without tension for long times, maybe this is the case? I can't explain this behaviour :-// |
| JohanH:
Mine had erratic behavior in 4W mode, front input, due to cracked solder on input resistors (the large 2512 resistors near the terminal). Front panel was cracked and terminal latch was missing entirely. This caused bending of the PCB every time someone inserted leads into the front terminal jacks. Soldering the resistors again helped (and of course fixing the cracked front panel and getting a new terminal latch to secure everything together). |

Obviously the failure of the T.O. vanished, so this case can be closed. |
