5
/PASS
The output is LOW when the test result is PASS, at this time
/HIGH, /LOW, /ARC_FAIL, /GFI_FAIL and /SHORT_FAIL
signal will not have output (all are HIGH).
6
/HIGH
Test result is HIGH FAIL, the output is LOW.
7
/LOW
Test result is LOW FAIL, the output is LOW.
19
/SHORT_F
AIL
Test result is SHORT_FAIL, the output is LOW.
20
/ARC_FAI
L
Test result is ARC_FAIL, the output is LOW.
21
/GFI_FAIL
Test result is GFI_FAIL, the output is LOW.
15,18
NC
Output
Reserved, not used yet.
1
/PA
Output
When the test is started, this signal is LOW, after each PA mode,
the relationship between the /PA signal and the COM terminal is
changed to HIGH or LOW once.
14
/SYSTEM
ERROR
Output
Internal system error signal output pin, when the output is LOW,
it indicates that the system generates an internal error.
16
/EOT
Output
When this signal is HIGH, it means the test is in process; when
this signal is LOW, it means the test is finished or in standby.
17
/EOS
Output
When this signal is HIGH, the test step (STEP) is currently is in
process; When this signal is LOW, it means that the current test
step (STEP) has ended without entering the next step or all test
steps have ended.
