Diagnostic Tests
2-18
SYSTEM
Tests the integrity of the core processing system and checks
the Lithium backup battery.
Data Card
The Data Card test writes a small file to the data card, reads it back
and checks it, then erases that file. If no Data Card is present, the
test result will be Not Tested.
CODEC
The processor turns on the CODEC (coding/decoding) chip (used
for voice prompts), and gets an acknowledgement that it's ready to
receive data. It does not give the CODEC data to process.
IRDA
Tests the infrared communications port. If no active infrared device
is within range, the test result will be Not Tested.
Timebase
The Timebase test compares the Real Time clock to the System
clock to check for discrepancies. It does not test the SpO
or the Biphasic clock.
DEFIB
The Defib test charges the defibrillator capacitor and then disarms it.
It does not deliver the energy outside the unit. The pads cable and
test load must be connected for the test to run; otherwise the test
result will be Not Tested.
FE
The Front End (FE) test checks that the main processor is
communicating with the Digital Signal Processor (DSP), and that
the DSP is communicating with both ECG front ends (pads and
leads). It does not test the quality of the ECG measurement.
SP02 (if SpO
option installed)
2
This tests that communication with the SpO
does this by reading the software revision back from the PCA.
It does not test the quality of the SpO
Pacer (if Pacing option installed)
The Pacer test has the Pacer deliver current into the test box, and
measures that the current delivered was what was expected. The
pads cable and test load must be connected for the test to run;
otherwise the test result will be Not Tested.
