13.1.9 To check Analog Interface A
With this diagnostic step the analog inputs of Interface A can be checked for their function-
ality. For this test the testbox with article number 1.767.0010 is required.
1.
Prepare instrument for diagnostic test (see chap. 13.1.2).
2.
<Analog interf.>
Ä On the screen there appears a window with the choice of selecting between analog interface A or B.
3.
With the cursor key, mark the letter A to select analog interface A.
4.
<ENTER>
5.
Connect Simulator to Titroprocessor accord. to Fig. 2.
6.
