Component Assembly Steps

1 Bend the component wires 90o.

2 Insert component pins intocorresponding holes oncircuit board. The resistormust rest on the top, labeledside of the board.

3 Gently bend the leadsunder the board wheninstalling to get a goodmechanical connection.

4 Turn the PCB over sothat the component isface down and thewires are exposed.

5 Solder eachcomponent leg to theboard.

6 Using the wirecutters, cut theexcess length ofresistor wires asclose to the board aspossible.

MyDAQ Test Procedures

1 Connect the MyDAQ board AI (analog input) circuit to the ECG Simulator, as shown inthe image.

2 Connect the acquisition board to the computer through a USB cable.

3 Open the program "NI ELVISmx Instrument Launcher".

4 Select the Scope option.

5 Enable Channel 1 and Channel 2. Use the same settings as a normal oscilloscope, 10mV Volts/Div scale and 100 ms Time/Div.

6 Click in the Run button.
