Test procedure
Perform the steps in Table 5-1 to test the shunt bar on a single inflator. The test current for
this measurement cannot exceed 1mA due to the dry circuit hardware limit. See Table 5-2
for an example of a test sequence for dual inflator.
I-source readback
The 7751, 7752, and 7753 modules have source readback capabilities. I-source readback
allows you to verify the test current used for the shunt bar test. Details on I-source read-
back are provided in the last topic in this section.
