4.9.24 Self Test (J)
The self test command, .~llows you to test I"\I& of the in-
ternal circuitry of the Model i94, including front panel
display segments, RAM, ROM, as well as many A!D con-
verter circuits.
The self test is run by sending the following command over
the bus:
The instrument will then run the test and set the self test
bit in the Ul status word, if a failure ocwrs. A complctc
description of the Ul (error) status word may be found in
paragraph 4.9.15. The values listed in the J byte portion
of the UO word will be returned, as summarized in lable
4-33.
