PASS / FAIL:
In autotest and individual measurements the status of measurement (PASS / FAIL) is given on pin 2 of EXT / DOOR IN connector.
If the measurement result is inside the range of limit then pin 2 is HI level. If the measurement is out of limit range then pin 2 is LO
level.
pin 2 – HI level:
- the next program step of the autotest will be executed
pin 2 – LO level:
- press START key to restart measurement
- press Skip key - program will continue with the next step
- press Exit key to stop program execution and return to
AUTOTEST menu
External:
Pin 3 of DOOR IN input is supported by Autotest program command ‘ Wait for external input’.
Generally the user can define four different kind of pause between too sequent measurements.
1.
Predefined time pause - common equal pause between measurements (it can be set from 1 s to 5 s in sequence editor:
Program name / Pause).
2.
Time pause – it has to be inserted as a ‘Pause’ command as the last command in the *.SQC program. In this case the total
pause between two sequent measurements is predefined time pause + Time of ‘Pause’ command.
3.
Message - it has to be inserted as a ‘Message’ command in the*.SQC program. The instrument waits for the user reaction
(connect test leads to tested object and press START).
4.
Wait for external input – this command waits for change from HI to LO on pin 3 of DOOR / IN input (see figure below.)

Application example – unpredictable pause time for the same action (manual action is part of preparation for another mea-
surement).
Next test:
Pin 4 indicates the end of execution of each measurement (change from LO to HI). Immediately after the start of another
measurement it changes from HI to LO state.
