Hi, I have this code in matlab, function VEB_Callback(hObject, eventdata, handles) global VE; ljud_LoadDriver; % Loads LabJack UD Function Library ljud_Constants; % Loads LabJack UD constant file [Error ljHandle] = ljud_OpenLabJack(LJ_dtU6,LJ_ctUSB,'1',1); % Returns ljHandle for open LabJack Error_Message(Error) % Check for and display any Errors if(Error==0) set(handles.ONOFF,'Value',1) end [Error VE] = ljud_eGet(ljHandle,LJ_ioGET_AIN_DIFF,2,0,3) Error_Message(Error) % Check for and display any Errors set(handles.VE,'String',1000*VE) It works with a button "VEB" and a textbox "VE" When there is not a load and I push de Button the reading is erratics. Always change even short time between a reading and other. What is the DAC reading. Is that normal. could this afeccts my reading. Thanks,

Are you saying you get unpredictable readings from floating analog inputs? That is normal:
