Managed to get my hands on a DP832 and calibrated two channels so far and getting -low mV on those. Tried 3 times and getting same results. Not touching/calibrating the remaining one (CH3) as I need this one to work in case the CH1 & CH2 are ruined. Using a DM3058E as ref/source and the SCPI procedures & table found earlier in this thread. CH1 0V/OFF == -46.3mV after calibration CH2 0V/OFF == -151.1mV after calibration :wtf: CH3 0V/OFF == 0mv (untouched factory calibration) Used to be all 0mV before calibration. Are those two channels' ADCs fried and do I need to get myself another DP832? Easy repair maybe?? Any advice (help!) welcome |

@Mecanix: You may want to have a look here, the peculiar behaviour of the DP832 when calibrating the low end of the voltage range, is dealt with there to some degree. It should be possible to get the offset sorted with this information, yet, as it seems, only by means of an automated calibration. |
