Regarding scaling raw data

[andyjung12]

For this preprocessing code :

% ensure the signal is calibrated to microvolts if(max(chan_data_eeg) <= 10) disp('Signal calibrated!'); chan_data_eeg = chan_data_eeg * 1000; end

It says that the signal is calibrated to microvolts, but the signals are multiplied by 1000. Shouldn't the signals be multiplied by 1,000,000, since the signals are in volt scale?
