Unit Diagnosis / Calibration
2
2 - 2 SpaceStation, 1.0 gb
The unit check, calibration and trouble shooting are subdivided
into numbered working steps (Unit Test Step UTS, Calibration Step
CS, Trouble Shooting TS) and are based on each other.
Beginning with UTS 1 the operation described here has to be ex-
ecuted. The consequences of the steps performed are listed in the
“Function“ column. If the result corresponds to the consequence,
the working step must be carried out to which reference is made
in the column “If yes”. If the result does not correspond with the
function described, the working step in column “If no” is to be ex-
ecuted.
One example is given in Abb.: 2 - 1 .
Steps for which additional information is required are described
hereafter in detail.
