why can't i use ni daq to read milli volt signal however labview did on the same daq?

%%get connected devices
d = daq.getDevices
%create session
s = daq.createSession('ni')
%add analog channel s.addAnalogInputChannel('ID',channel num, 'measurement type')
s.addAnalogInputChannel('Dev1',0, 'Voltage')

% set rate of scan 4 scans/second , run for 3 seconds

v= s.Channels(1);
v.TerminalConfig = ' Differential ';
v.Coupling = ' DC';

%start continuous aquisition and plot

h = s.addlistener('DataAvailable', @(src,event) plot(event.TimeStamps, event.Data/1));
s.NotifyWhenDataAvailableExceeds = 200;
%start sample aquisition and plot
%[data,time] = s.startForeground;
%irradiation = data/1
grid on
xlabel('Time (sec)')
ylabel('voltage in v')
