Note
: If the ports on your PC are not labeled and you don’t know the COM port you are using
for your ADC1000-USB, you may have to resort to trial and error. If you choose the
wrong serial port number, you will not see a dynamic trace responding to light near the
bottom of the displayed graph. Instead, you will see a straight line at 0 counts.
