Rigol DP832 - Firmware list and bugs
EEVblog:
I get about 30uA and 30V AC between output and earth.
I don't see the issue, you'll get this with almost any supply, capacitive coupling between output and mains earth is quite normal.
My BK Precision 1697 is 30V and 110uA
If for some reason this is an issue with your system, mains output reference your supply, that is what the earth terminal is on the front panel for.
SimonD:
Is there anyone who have try this new update ( Version:00.01.02.00 - 2015-03-16 ) of software ?

Works well on DP832 ?
If yes, can anyone post some screenshots ?
Thank you!

Color display is not a big deal but I'm curious if you know something about this ?

FYI: No firmware update needed for that multicolor look. The below display settings should reproduce the above colors...
Brightness: 50%
Contrast: 85%
RGB Lum: 45%
Disp Mode: Waveform
Theme: Orange (Transitions to yellow as above settings are input...)

I've discovered a CH3 OCP firmware related bug. OCP functions as expected on CH1/CH2 and OVP functions as expected on CH1/CH2/CH3.
Particulars for my Rigol DP832 unit:
NOTE: My unit is equipped with TopBoard_V02.20 / BottomBoard_V02.20.
Recreating firmware bug:
CH3 in CC mode set to 100mA. My Fluke 87V confirms output is bang on at 100.1mA. Readback is 2mA low but well within tolerance.
I increase CH3 set current until it exceeds set/enabled OCP limit of 110mA. However, CH3 remains ON. I continue increasing set current to 1A. My Fluke 87V confirms output stops increasing after I pass 110mA on set current and remains at a max of 110.1mA. Readback is again 2mA low but confirms actual output is at the set OCP limit.
I turn CH3 OCP OFF. V/A/W readback remains unchanged and again, my Fluke 87V confirms an actual output of 110.1mA.
I increase CH3 set current by 1mA to 1.001A. My Fluke 87V immediately registers an output current increase to 1.0011A. V/A/W readback immediately updates to correctly reflect the new output level.
I turn CH3 OCP ON. CH3 immediately registers an OCP event, displays a popup warning window and turns CH3 OFF.
I turn CH3 ON. CH3 remains ON regardless of the set current level which exceeds OCP limit. My Fluke 87V confirms an output of 110.1mA. Readback is again 2mA low but confirms actual output is at the set OCP limit.
NOTE: The 110mA CH3 OCP limit I chose to demonstrate this bug at doesn't matter. I've recreated this bug with CH3 OCP limit set to 10mA, 510mA, 1.010A, 1.510A, 2.010A and 2.510A.

I've discovered a ManualCal/Key Lock Password firmware related bug. The factory default password is "2012". If you successfully modify the password, ManualCal recognizes the new password. If you have Key Lock enabled (Utility>>System>>Key Lock) and lock the front panel, the new password is recognized when you unlock the front panel. However, power-cycle the unit and the password reverts back to the factory default "2012".

NOTE: My unit is equipped with TopBoard_V02.20 / BottomBoard_V02.20.
