7.1.1. DSC Self-Test
The Digital Signal Conversion (DSC) Self-Test verifies the signal acquisition and
conversion functions of the BISx module, and tests the entire signal processing chain
inside the BISx module.
It does not test the PIC or the sensor.
The BISx module must be connected to perform DSC self-test; a sensor may be
connected but is not required.
The DSC Self-Test analyzes Noise, High-Pass Blocked, High Pass Normal, and Gain
data from two channels or four channels, depending on the type of system (two-
channel or four-channel). All results are in microvolts.
The DSC Self-Test will return a PASS result if all channels pass the test, and a FAIL
result if one or more channels fails the test. The numerical values for any channel that
passes the DC self-test shall be displayed.
To perform the DSC Self-Test, follow the steps listed below:
1. Click Main Menu>Settings and Maintenance>Maintenance>DSC
Self-Test.
2. Click START.
3. The DSC Self-Test will proceed; an on-screen message will indicate DSC
Self-Test is in progress. The DSC Self-Test cannot be stopped during the

Test PASS or DSC Self-Test Failed at the bottom of the screen. If the
