(D-FF-Test Nr. 0) tests the external control bus for signal lines d0–d7. The signal lines d0–d7 are
switched on and off one after another. The switching statuses can be displayed on the bar graph (adapter
board 30183-102).
Using the keys 8 (Up) or 9 (Down), you can call up D-FF tests 1-11. You will see the following display:

The D-FF signal lines d0-d7 are switched on and off one after another. The signals can be measured at the
D-FF outputs. There is an error if
• there is more than one output status at the same time,
• there is constantly an output signal in spite of switching over,
• there is no output signal in spite of D-FF activation.
