Analog Input Test
The Analog Input Test monitors the voltage of the DC input of the ANA/TTL connector.
To conduct this test, select Analog Input Test and follow the on-screen instructions to
connect a DC power supply to the DC input pins of the ANA/TTL connector. The test
will check the voltage of the DC input and display the results on the screen.
DCOut Loopback Test
The DCOut Loopback Test monitors the connection of the DC Outputs to the DC Inputs.
To conduct the test, select DCOut Loopback Test and follow the on-screen instructions
to connect the DC outputs to the analog input pins on the ANA/TTL connector. The
test then sends all possible values out of the DC Outputs and confirms that the same
values are received by the Analog Inputs. Refer to
page 79
When the test is complete, Passed or Failed will be displayed on the screen, depending
on the results.
ECGOut/QRSTrigger Loopback Test
The ECGOut/QRSTriggger Loopback Test monitors the connection of the ECG Outputs
and TTL Trigger Outputs to the DC Inputs.
To conduct the test, select ECGOut/QRSTrigger Loopback Test and follow the
on-screen instructions to connect the ECG outputs and QRS trigger outputs to the
analog input pins on the ANA/TTL connector. The test then sends all possible values
out of the ECG outputs and a square wave out of the QRS trigger output and confirms
that the same values are received by the Analog Inputs. Refer to
Connectors" on page 79
When the test is complete, Passed or Failed will be displayed on the screen, depending
on the results.
